This is a complete reference of all available Fluid
view helpers in the TYPO3 Core.
Fluid is a PHP template engine and is the de facto standard for any
HTML-based output in the TYPO3 CMS. However, it is not dependent on
TYPO3 and can be used in any PHP project. See the Fluid standalone
documentation.
Note: This documentation was generated
from the PHP source code of TYPO3.
In the AssetCollector, the "identifier" attribute is used as a unique identifier. Thus, if assets are added multiple
times using the same identifier, the asset will only be served once (the last added overrides previous assets).
Some available attributes are defaults but do not make sense for this ViewHelper. Relevant attributes specific
for this ViewHelper are: as, crossorigin, disabled, href, hreflang, importance, integrity, media, referrerpolicy,
sizes, type, nonce.
Using the "inline" argument, the file content of the referenced file is added as inline style.
Asset.module ViewHelper <f:asset.module>
ViewHelper to add JavaScript modules to the TYPO3 AssetCollector.
In the AssetCollector, the "identifier" attribute is used as a unique identifier. Thus, if modules are added multiple
times using the same module identifier, the asset will only be served once.
In the AssetCollector, the "identifier" attribute is used as a unique identifier. Thus, if assets are added multiple

Some available attributes are defaults but do not make sense for this ViewHelper. Relevant attributes specific
for this ViewHelper are: async, crossorigin, defer, integrity, nomodule, nonce, referrerpolicy, src, type.
Using the "inline" argument, the file content of the referenced file is added as inline script.
Asset.styleAttr ViewHelper <f:asset.styleAttr>
ViewHelper for inline style attributes that need CSP hash coverage via style-src-attr.
When csp is true (default), the style value is hashed and registered with the HashCollection so that the CSP header includes the corresponding sha256-... hash.

The public constants in
InfoboxViewHelper
for defining the state/severity of an infobox have been deprecated. Use
the enum
\TYPO3\CMS\Core\Type\ContextualFeedbackSeverity instead.
The Infobox provides different context-sensitive states that
can be used to provide an additional visual feedback to the
user to underline the meaning of the information.
The state property allows enums of type
\TYPO3\CMS\Core\Type\ContextualFeedbackSeverity
and integer values between -2 and +2 for backward compatibility.
A demonstration of all possible states
ContextualFeedbackSeverity::NOTICE (-2)
Notices (Default)
ContextualFeedbackSeverity::INFO (-1)
Information
ContextualFeedbackSeverity::OK (0)
Positive feedback
ContextualFeedbackSeverity::WARNING (1)
Warnings
ContextualFeedbackSeverity::ERROR (2)
Error
It is considered best practice to use the states from
\TYPO3\CMS\Core\Type\ContextualFeedbackSeverity enum together with the
Constant ViewHelper <f:constant>:
<?php// BeforeuseTYPO3\CMS\Fluid\ViewHelpers\Be\InfoboxViewHelper;
$state = InfoboxViewHelper::STATE_ERROR;
// After - Recommended: Use the enum directlyuseTYPO3\CMS\Core\Type\ContextualFeedbackSeverity;
$state = ContextualFeedbackSeverity::ERROR;
// Alternative: Use the integer value when explicitly needed
$stateValue = ContextualFeedbackSeverity::ERROR->value;

Inserting this ViewHelper at any point in the template,
including inside conditions which do not get rendered,
will forcibly disable the caching/compiling of the full
template file to a PHP class.
Use this if for whatever reason your platform is unable
to create or load PHP classes (for example on read-only
file systems or when using an incompatible default cache
backend).
Passes through anything you place inside the ViewHelper,
so can safely be used as container tag, as self-closing
or with inline syntax - all with the same result.
Examples
Self-closing
<f:cache.disable />
Copied!
Inline mode
{f:cache.disable()}
Copied!
Container tag
<f:cache.disable>
Some output or Fluid code
</f:cache.disable>

Additional output is also not compilable because of the ViewHelper
Used around chunks of template code where you want the
output of said template code to be compiled to a static
string (rather than a collection of compiled nodes, as
is the usual behavior).
The effect is that none of the child ViewHelpers or nodes
used inside this tag will be evaluated when rendering the
template once it is compiled. It will essentially replace
all logic inside the tag with a plain string output.
Works by turning the compile method into a method that
renders the child nodes and returns the resulting content
directly as a string variable.
You can use this with great effect to further optimise the
performance of your templates: in use cases where chunks of
template code depend on static variables (like thoese in
{settings} for example) and those variables never change,
and the template uses no other dynamic variables, forcing
the template to compile that chunk to a static string can
save a lot of operations when rendering the compiled template.
NB: NOT TO BE USED FOR CACHING ANYTHING OTHER THAN STRING-
COMPATIBLE OUTPUT!
USE WITH CARE! WILL PRESERVE EVERYTHING RENDERED, INCLUDING
POTENTIALLY SENSITIVE DATA CONTAINED IN OUTPUT!
Examples
Usage and effect
<f:if condition="{var}">Is always evaluated also when compiled</f:if>
<f:cache.static>
<f:if condition="{othervar}">
Will only be evaluated once and this output will be
cached as a static string with no logic attached.
The compiled template will not contain neither the
condition ViewHelperNodes or the variable accessor
that are used inside this node.
</f:if>
</f:cache.static>
Copied!
This is also evaluated when compiled (static node is closed):
<f:if condition="{var}">Also evaluated; is outside static node</f:if>
since TYPO3 v14.2, will be removed in TYPO3 v15.0.

Form ViewHelper <f:form>
ViewHelper to generate a <form> tag and prepare context for further <f:form> ViewHelpers within that form. Tailored for Extbase plugins, uses Extbase Request.
The Extbase Controller action displaying the form then creates the Domain object
and passes it to the view. In the Fluid template above we use argument
object
to pass any data the object might already contain to the ViewHelper.
By using the argument "property" on the form input elements the properties of
the model are automatically bound to the input elements.
<?phpdeclare(strict_types=1);
namespaceMyVendor\MyExtension\Controller;
usePsr\Http\Message\ResponseInterface;
useT3docs\BlogExample\Domain\Model\Comment;
useT3docs\BlogExample\Domain\Repository\CommentRepository;
useTYPO3\CMS\Extbase\Annotation\IgnoreValidation;
useTYPO3\CMS\Extbase\Mvc\Controller\ActionController;
classCommentControllerextendsActionController{
publicfunction__construct(
protected readonly CommentRepository $commentRepository,
){}
#[IgnoreValidation(['argumentName' => 'newComment'])]publicfunctioncommentFormAction(?Comment $newComment = null): ResponseInterface{
if ($newComment === null) {
$newComment = new Comment();
$newComment->setDate(new \DateTime());
}
// The assigned object will be used in argument object$this->view->assign('newComment', $newComment);
return$this->htmlResponse();
}
publicfunctioncreateAction(
// This parameter must have the same name as argument `objectName` of f:form
Comment $comment,
): ResponseInterface{
$this->commentRepository->add($comment);
$this->addFlashMessage('Comment was saved');
return$this->redirect('show');
}
}
Copied!
If the model is not valid (see Validation)
Extbase will automatically refer the request back to the referring action
(here commentFormAction()). By passing the object with the non-validated object
to the view again, the user can see their faulty inputs and correct them instead
of seeing an empty form.
Security in Fluid forms
Fluid automatically adds several hidden field to forms:
__referrer[] with an array of items @extension, @controller,
@action, arguments and @request. This holds information about
where the form has been created, so that in case of errors,
redirection to the originating Extbase controller and action
(and extension) is possible.
__trustedProperties (string) holds information about all used properties
of all Extbase domain models that have been utilized within the
related <f:form> context. This is used to ensure only properties
will be evaluated for persistence that have an editable form field
associated with them.
To prevent tampering with this vital data, the important fields
(__referrer[arguments], __referrer[@request], __trustedProperties)
are signed with the private TYPO3 encryption key using an HMAC
hash.
If form fields are added or removed via attacks, Extbase detects the
mismatch and blocks further processing.
Form fields can be grouped in an array for efficient processing. An
internal Extbase processing action maps the received data to a model,
where (optional and configurable) validation occurs.
Only valid data is passed on to the action and stored in
the database.
They cannot be used in Fluid Components in TYPO3 13.4.
In Components
(introduced with Fluid 4.3) a new rendering context is created for
each Fluid component. Therefore form fields loose the connection
to their parent form and cannot be used.
It is however possible to pass a form field to a slot:
This ViewHelper allows you to pass arbitrary arguments not defined below
directly to the HTML tag created. This includes custom data- arguments.

A Fluid form with multiple buttons of different types
The <f:form.button> ViewHelper supports the type attribute, allowing you to
render buttons of type submit, reset, or button. This is useful when you
want to offer multiple actions within the same form, each with a distinct
purpose and custom styling or icons.
Unlike <f:form.submit>, you can include inline HTML (e.g. icons, spans) in each button.
<?phpnamespaceVendor\MyExtension\Controller;
useMyVendor\MyExtension\Domain\Model\Comment;
usePsr\Http\Message\ResponseInterface;
useTYPO3\CMS\Extbase\Mvc\Controller\ActionController;
classCommentControllerextendsActionController{
publicfunctionsubmitAction(Comment $comment, string $action): ResponseInterface{
switch ($action) {
case'save':
// Save logic here$this->addFlashMessage('Comment saved!');
return$this->redirect('edit');
case'preview':
// Assign preview-related data and render the same view$this->view->assign('preview', true);
$this->view->assign('comment', $comment);
return$this->htmlResponse();
default:
$this->addFlashMessage('Unknown action');
return$this->redirect('edit');
}
}
}
Copied!
Note
The reset button does not submit the form and is not processed by the controller.
It resets all form fields to their initial values using standard HTML behavior
(<button type="reset">). Therefore, there is no need to handle it in the controller.
Note
When using multiple buttons, you can assign different name and value attributes
to detect which button was clicked in the controller.
A button with additional HTML5 attributes
The <f:form.button> ViewHelper allows you to pass through standard HTML5
button attributes such as disabled, formmethod, and formnovalidate.
This is useful when you need more control over how the button behaves in relation to
form submission and validation.
You can use these attributes with any button type (submit, reset, or button) and
they will be passed through to the rendered <button> tag.
A button with accessibility attributes
The <f:form.button> ViewHelper supports accessibility attributes like aria-label,
aria-disabled, or aria-describedby.
These attributes are passed directly to the rendered <button> tag, allowing you to make your forms
more accessible for assistive technologies such as screen readers.
For convenience, you can also use the
aria
attribute and pass an array to it.
Fluid will automatically generate the corresponding aria-* attributes
based on the key-value pairs in the array.
<htmlxmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers"data-namespace-typo3-fluid="true"><f:formaction="submit"controller="Comment"object="{comment}"objectName="comment"method="post"><labelfor="tx-comment-content">Message:</label><f:form.textareaproperty="content"id="tx-comment-content"rows="6"cols="50" /><pid="commentHint"class="form-text">

Form.checkbox ViewHelper <f:form.checkbox>
ViewHelper which renders a simple checkbox <input type="checkbox">.
A single checkbox is usually mapped to a boolean property or controller
argument.
However due to how checkboxes work in HTML a non-checked checkbox does not
appear in the request sent by the form submission. Therefore properties and arguments
need to default to false. They will then be set to true if the checkbox
was checked.
While the value
does not play a role when you are working with a checkbox, the argument must still
be supplied.
Single optional checkbox tied to an action argument
Checkboxes in HTML work a little different from other input fields in that
multiple or none at all can be checked.
Fluid outputs a normal HTML <input type="checkbox" ...>
and some of the pitfalls also apply here. Especially a check box that is not
sends no argument to the request.
<?phpdeclare(strict_types=1);
namespaceMyVendor\MyExtension\Controller;
usePsr\Http\Message\ResponseInterface;
useTYPO3\CMS\Extbase\Mvc\Controller\ActionController;
classNewsletterControllerextendsActionController{
publicfunctionorderNewsletterAction(
// If the checkbox is not checked, no argument is provided.
// Default to false
bool $orderNewsletter = false,
): ResponseInterface{
if ($orderNewsletter) {
// TODO: Newsletter ordering
}
return$this->htmlResponse();
}
}
Copied!
Note
If a checkbox is not checked it sends NO argument as opposed to a text input
with no text entered. Therefore in the Extbase action you must supply
a default for the argument if non-checked fields should be allowed.
The checkbox should already by checked / preselected
If the property in the domain model is true when the form is displayed, the
checkbox is preselected.
Multiple checkboxes for the same property
Unlike other input elements, multiple checkboxes can be used for the same
property or action argument.
In this case they share the same name
or property binding property
but have distinct values.
If you are working with action arguments, multiple
must be set.
Multiple checkboxes mapped to an array in a controller action
Multiple checkboxes are usually mapped to an array. It would however be possible, for example,
to map them to an integer using binaries or such.
Therefore when working with multiple checkboxes and arrays, you have to tell
Extbase how to map the data from the request to your controller action in an
initialize action.
<?phpdeclare(strict_types=1);
namespaceMyVendor\MyExtension\Controller;
usePsr\Http\Message\ResponseInterface;
useTYPO3\CMS\Extbase\Mvc\Controller\ActionController;
useTYPO3\CMS\Extbase\Property\TypeConverter\ArrayConverter;
classNewsletterControllerextendsActionController{
publicfunctionorderNewsletterAction(
// This argument is mapped in initializeOrderNewsletterAction()
array $orderNewsletters = [],
): ResponseInterface{
if ($orderNewsletters !== []) {
// TODO: Newsletter ordering
}
return$this->htmlResponse();
}
publicfunctioninitializeOrderNewsletterAction(){
if ($this->request->hasArgument('orderNewsletters')) {
$this->arguments['orderNewsletters']
->getPropertyMappingConfiguration()
->setTypeConverterOption(
ArrayConverter::class,
ArrayConverter::CONFIGURATION_DELIMITER,
',',
);
}
}
}
Copied!
Note
See class
\TYPO3\CMS\Extbase\Property\TypeConverter\ArrayConverter
for details on mapping arrays.
Property mapping of multiple checkboxes
When working with multiple checkboxes mapped to the property of an Extbase model
or data object, the same
property
is used for all checkboxes to be mapped to that property.
Note
An example is still missing. You can help by providing an example.
Click the "report issue" button above and hand in your examples.
Multiple checkboxes for multiple independent properties
When multiple checkboxes should be used independently they must have unique
name
properties to map to multiple action arguments or unique
property
values to bind to multiple properties.
Mandatory checkboxes - require a checkbox to be set
On the browser side you can use the HTML 5 "required" Attribute.
As the <f:form.checkbox> ViewHelper allows arbitrary arguments, using
the required property is possible even though it is not listed.
<f:flashMessages/><f:formaction="orderNewsletter"method="post"object="user"objectName="user"><div><f:form.checkboxproperty="consentGiven"id="consentGiven"value="yes"required="required"/><labelfor="consentGiven">I have accepted the terms and conditions</label></div><div><f:form.submitvalue="Submit" /></div></f:form>
Copied!
Then the controller action can then look like this:
If the server side validation on the model fails, the request is forwarded to
the originating request with an error message.

Tip
In a <f:form> with the method
set to post, the content of hidden fields is sent in the POST body.
This is ideal for data that should not be visible in the URL or is too
large to include in the query string.
Use case: Creating a comment for a specific blog post
You have:
A Comment domain model that relates to a BlogPost
A BlogPost detail page that includes a comment form
The property blogPost is set automatically and not selectable by the user
Use a hidden field to bind a new object (like a Comment) to its parent
(like a BlogPost). This keeps the relation intact without exposing
it in the user interface.
In this example, the blogPost property is set via a hidden input and
automatically mapped back to a domain object using Extbase's property
mapping.

Form.password ViewHelper <f:form.password>
ViewHelper which renders a simple password text box <input type="password">.
Password fields should never be prefilled with sensitive data.
Always use secure handling on the server side to hash and verify passwords.
Never persist or display passwords as plain text. See also
Excursion: Validation and hashing of password fields.
Excursion: Validation and hashing of password fields
A password should be validated against the
Password policy
and must always be hashed before saving. Never save a plain text
password to the database.

The example above shows validation inlined in an action of the controller for brevity.
For re-usability and better architecture following best practices, you can create a custom

Form.radio ViewHelper <f:form.radio>
ViewHelper which renders a simple radio button <input type="radio">.
When using multiple related radio buttons, wrap them
in a <fieldset> with a <legend>, which helps screen readers understand
the purpose of the group and improves overall accessibility. It also gives
your form better semantic structure.
<f:formaction="orderNewsletter"method="post"><fieldset><legend>Would you like to order the newsletter?</legend><f:form.radioname="orderNewsletter"id="orderNewsletterYes"value="1"/><labelfor="orderNewsletter">Yes</label><br><f:form.radioname="orderNewsletter"id="orderNewsletterNo"value="0"checked="1"/><labelfor="orderNewsletterNo">No</label><br></fieldset><f:form.submitvalue="Submit"/></f:form>
You could ask the same question with a
Single optional checkbox.
The main difference is, when you have a preselected radio button, the radio
button group cannot be disabled again, therefore the parameter is always
supplied to the action.
Property mapping - Radio buttons bound to a model
The radio buttons from this example look the same as those from the previous
example, however an object of type User is now provided as parameter for
the Extbase action.
<f:formaction="orderNewsletter"method="post"object="user"objectName="user"><fieldset><legend>Would you like to order the newsletter?</legend><f:form.radioproperty="orderNewsletter"id="orderNewsletterYes"value="1"/><labelfor="orderNewsletter">Yes</label><br><f:form.radioname="orderNewsletter"id="orderNewsletterNo"value="0"checked="1"/><labelfor="orderNewsletterNo">No</label><br></fieldset><f:form.submitvalue="Submit"/></f:form>
Radio buttons with options from an array or query result
The form radio ViewHelper does not supply an argument that creates it from
an array as you might have seen for the form select ViewHelper
(Select field for selecting (persisted) models).
You can however just use the For ViewHelper <f:for>
to iterate your items and display them one by one. If you use the objects uid
for the key, the radio button can be matched to the model in use.
The Fluid template can be left unchanged even though we are dealing with a
different data source:
<?phpdeclare(strict_types=1);
namespaceMyVendor\MyExtension\Domain\Model;
useTYPO3\CMS\Extbase\DomainObject\AbstractEntity;
classPaymentMethodextendsAbstractEntityimplements \Stringable{
protected string $title;
protected string $paymentIdentifier;
// Getters and setters// If the model implement the __toString() method// The result of that method is displayed in the select formpublicfunction__toString(): string{
return$this->title;
}
}
Copied!
In the controller we can get all payment methods from the
Repository
now and pass it to the view as variable:
The integrator can choose to use a radio button or select element without
that the backend has to be changed.
Multiple radio button groups
Only one radio button per group can be checked at a time. Each group has the
same name
or property.
Tip
Each group of related radio buttons should be wrapped in its own
<fieldset> with a <legend> to describe the purpose of the group.
This ensures that screen readers and other assistive technologies can
correctly interpret the relationship between the options. It also improves
the semantic structure and visual clarity of your form.

Form.select ViewHelper <f:form.select>
ViewHelper which renders a <select> dropdown list for use within a form.

namespaceMyVendor\MyExtension\Domain\Model;
useTYPO3\CMS\Extbase\DomainObject\AbstractEntity;
classPaymentMethodextendsAbstractEntityimplements \Stringable{
protected string $title;

// Getters and setters// If the model implement the __toString() method// The result of that method is displayed in the select formpublicfunction__toString(): string{
return$this->title;
}
}
Copied!
In the controller we can get all payment methods from the
Repository
now and pass it to the view as variable:
When the form gets submitted, the UID of the chosen model appears in the request
data. Extbase will then map that uid back to the model for you.
The ViewHelper will then use the model's UID as data submitted in the form and
the result of method
__toString() as display text.
Note
You can pass any array or
\Traversable object to
the options
argument. This includes the result of findBy() methods on
Extbase repositories,
QueryResultInterface and objects
stored as relation in another object as
ObjectStorage .
optionLabelField: Define another property of the model for the option label
If the model to be displayed has no
__toString() method or you want to
display the content of a different field, use option
optionLabelField
The options
may contain an array or anything else Traversable including
optionValueField: Define another property of the model as value
If you are dealing with non-persisted models or Data-Transfer-Objects (DTO) there is
no valid identifier that could be used to automatically map the user's selection
in your controller. In this case, you must provide the name of the field to
be used to identify the object:
The <f:form.select.option> ViewHelper can be used to create a completely
<f:form.select.option>
<option> tags in a way compatible with the
HMAC generation.
To do so, leave out the options argument and use child ViewHelpers:
In HTML, the
<select> element always selects the first option, if nothing
else is selected. If the field is mandatory and the user should be forced to
make a selection or if an empty value should be possible, you need an empty
option as first option. You can use the argument
prependOptionLabel
to set a label for this object. The value of the option will be an empty string.
If you need another value, for example 0 because you are expecting an integer,
you can use
prependOptionValue.
<f:form.selectoptions="{user.availablePaymentOptions}"property="preferredPayment"prependOptionLabel="Ask me every time!"prependOptionValue="ask"
/>
<f:form.selectoptions="{user.availablePaymentOptions}"property="preferredPayment"optionsAfterContent="true"required="1"
><f:form.select.optionvalue="">Please Chose *</f:form.select.option><f:form.select.optionvalue="ask">Ask me every time!</f:form.select.option></f:form.select>
Copied!
It is possible to put the additional options last and combine the two:
<f:form.selectoptions="{user.availablePaymentOptions}"property="preferredPayment"prependOptionLabel="Please Chose *"required="1"
><f:form.select.optionvalue="ask">Ask me every time!</f:form.select.option></f:form.select>

Form.textarea ViewHelper <f:form.textarea>
ViewHelper which renders a <textarea> large text input area inside a form.
The value of the text area needs to be set via the value attribute, as with all other f:form ViewHelpers.
This example shows how to bind a textarea to an Extbase controller action
argument.
This approach is appropriate when you want to handle input directly in a
controller action, without relying on a domain model or Data Transfer Object (DTO).
Property binding: A text area bound to a model property
Using the property
argument, a text field can be bound to the property of an
Extbase model.
For this, the surrounding form must also define the
object
property. As the textarea ViewHelper may provide texts longer than 255 chars,
the TCA for the field should be of type Text areas & RTE.
This ensures that the auto-generated database field will also be of type
TEXT,
which is suitable for longer content.”

Form.textfield ViewHelper <f:form.textfield>
ViewHelper which renders a text field <input type="text">.
User input often requires validation. For text fields, some common cases include:
The name should not be empty
The email address must be a valid email address and it is required.
The link to the user's homepage must be a valid URL if it is entered at all.
Using arbitrary arguments
As the Form.textfield ViewHelper allows arbitrary arguments, you can use any
additional argument that you would also use on an HTML input element, including
HTML 5 arguments like required
and autocomplete.
ARIA arguments for improved accessibility
You have the choice of defining each aria-*
attribute separately as you would do in HTML, or by passing them as an array to
the Fluid argument aria.
Data arguments for JavaScript validation etc
Same goes with data-* attributes.
They can also be set with the Fluid argument
data
as an array. data-* attributes are commonly used with JavaScript libraries
for frontend validation like Parsley.
Server side validation
Warning
Never rely on frontend validation alone! It might not work in all browsers.

The Extbase controller
action commentFormAction() uses the IgnoreValidation
argument to disable the validation. Whenever the validation fails in the
createAction() the request will be forwarded back to this action. The
model still contains the non-valid data so that the user can edit it.

ViewHelper to render a string which can contain HTML markup by passing it to a TYPO3 parseFunc. This can sanitize unwanted HTML tags and attributes, and keep wanted HTML syntax and take care of link substitution and other parsing. Either specify a path to the TypoScript setting or set the parseFunc options directly. By default, lib.parseFunc_RTE is used to parse the string.
Note: The ViewHelper must not be used in backend context, as it triggers frontend logic. Instead, use <f:sanitize.html> within backend context to secure a given HTML string or <f:transform.html> to parse links in HTML.
Depending on the TCA definition of the rendered field nl2br is then
automatically applied for multi line text areas.
If you use TypoScript properties such as
field or
dataWrap,
you should pass structured data
(Data transfer object (DTO)
or named array) as data. This ensures that field references like
{FIELD:title} are resolved correctly.

With a custom parsing function defined in TypoScript:
HTML ignores line breaks within text. To display text while preserving line
breaks, you must convert newline characters such as \n or \r\n into
HTML line break elements

The <f:format.nl2br> ViewHelper uses PHP's
nl2br() function
to insert HTML line breaks.
The following arguments are available for the format.trim ViewHelper:

ViewHelper to generate a list of image URLs and their corresponding srcset descriptors to be used in a srcset attribute of an or tag.
Responsive images can either be defined based on absolute widths or relative pixel densities.
Width descriptors use the "w" unit, which refers to the width of the image file (not to be confused with "px", which refers to so-called CSS pixels in the HTML document). The srcset attribute in combination with the sizes attribute provide hints to the browser which one of the provided image files should be used. The browser is free to consider other factors, such as network speed, user preferences, or client-side caching status.
Density descriptors use the "x" unit and target client devices based on the pixel density of their screens. "1x" will be loaded for low-density devices, while "2x", "3x"... target higher densities, also referred to as "High DPI" or "Retina".
According to the HTML standard, "w" and "x" units cannot be mixed. Instead, browsers will usually consider the pixel density, even if "w" units are used. In practice, "x" is only relevant for fixed-width images across device sizes (e. g. an icon that always has the same visual size). In all other cases, "w" should be preferred.
The following arguments are available for the image.srcset ViewHelper:
absolute

The Page ViewHelpers provide access to page-level functionality in frontend
Fluid templates. They are used to control aspects of the rendered HTML
document that belong to the page itself rather than to individual content
elements.
Typical use cases include:
setting the document title
defining SEO and social media meta tags
injecting additional markup into the HTML <head> section
The Page ViewHelpers are designed to be used together and integrate with
TYPO3’s frontend rendering and MetaTagManager systems.
For detailed information about each ViewHelper and its arguments, refer to
the individual reference pages:
The following example shows how multiple Page ViewHelpers can be combined
in a PAGEVIEW
layout to manage common page-level concerns such as the document title,
SEO-related meta tags, OpenGraph and Twitter / X meta data, as well as
favicon and other <head> assets.
This approach is typically used in site packages and custom frontend
rendering setups where page title, meta data, and head markup are defined
centrally in a layout.
The <f:page.footerData> ViewHelper allows injecting arbitrary content right
before the closing
</body> tag of a rendered page.
The ViewHelper internally uses the PageRenderer API
and is useful when ViewHelpers like
<f:asset.css> or
<f:asset.script>
do not support all required attributes or use cases
(for example tracking code or inline JavaScript).
Warning
The ViewHelper outputs given content as is. Possible user supplied input for
the ViewHelpers must manually be escaped in order to prevent a
Cross-site scripting (XSS)
vulnerability.
<f:page.footerData><script>var _paq = window._paq = window._paq || [];
_paq.push(['trackPageView']);
_paq.push(['enableLinkTracking']);
(function() {
var u = "https://your-matomo-domain.example.com/";
_paq.push(['setTrackerUrl', u + 'matomo.php']);
_paq.push(['setSiteId', '1']);
var d = document, g = d.createElement('script'), s = d.getElementsByTagName('script')[0];
g.async = true; g.src = u + 'matomo.js'; s.parentNode.insertBefore(g, s);
})();
</script></f:page.footerData>

Page.headerData ViewHelper <f:page.headerData>
New in version 14.0
The <f:page.headerData> ViewHelper allows injecting arbitrary content into
the HTML
<head> of a rendered page.
The ViewHelper internally uses the PageRenderer API
and is useful when ViewHelpers like
<f:asset.css> or
<f:asset.script>
do not support all required attributes or use cases
(for example dns-prefetch, preconnect, tracking scripts, or inline
JavaScript).
Warning
The ViewHelper outputs given content as is. Possible user supplied input for
the ViewHelpers must manually be escaped in order to prevent a
Cross-site scripting (XSS)
vulnerability.
The Fluid ViewHelper
<f:page.meta> allows meta tags to be defined
directly within Fluid templates by leveraging TYPO3's MetaTagManager API.
This allows frontend rendering logic—such as Extbase plugins, Fluid-based
content elements, or site package templates—to control meta tags (for
example descriptions, OpenGraph data, and social media cards) directly in
Fluid templates, without requiring custom PHP logic.
Meta tags can be defined and managed directly in Fluid templates, reducing
or eliminating the need for additional TypoScript configuration in many
common scenarios.
Using the <f:page.meta> ViewHelper
The following examples demonstrate common use cases for the
<f:page.meta> ViewHelper in frontend Fluid templates. They show how
meta tags can be defined, extended, and replaced directly in Fluid while
integrating with TYPO3's MetaTagManager system.
Set meta tags in a detail view template
Meta tags can be defined directly in a Fluid template, for example in a
detail view that renders a single domain object.
Existing meta tags with the same property can be replaced explicitly when
required.
<f:page.metaproperty="description"replace="true">
Override any existing description
</f:page.meta>
Copied!
All examples shown above integrate with TYPO3's MetaTagManager system and
respect configured meta tag managers, priorities, and rendering rules.
This enables a template-centric approach to managing SEO-relevant meta
data that reflects the rendered content accurately.
Arguments of the <f:page.meta> ViewHelper
Allows arbitrary arguments
This ViewHelper allows you to pass arbitrary arguments not defined below
directly to the HTML tag created. This includes custom data- arguments.

Page.title ViewHelper <f:page.title>
New in version 14.0
The ViewHelper allows setting the page title directly from Fluid templates.
This is especially useful for Extbase plugins that need to set a page title
in their detail views without having to implement their own custom page title provider.
Intercepting the rendering of content areas via an event
Developers can intercept the rendering of content areas in Fluid templates using
\TYPO3\CMS\Fluid\Event\ModifyRenderedContentAreaEvent to modify output.
Arguments of the <f:render.contentArea> ViewHelper
contentArea
contentArea
Type
TYPO3\CMS\Core\Page\ContentArea
A content area from the page-content processor
recordAs
recordAs
Type
string
Name of the variable to store the current record in, if you want to use it in the before/after content.
Render.record ViewHelper <f:render.record>
New in version 14.2
Instead of using the
<f:cObject> ViewHelper to render database records,
use the new
<f:render.record> ViewHelper.
This ViewHelper renders a record object via its TypoScript definition. The
most common use case is rendering a content element that is available as a
record object in a Fluid template.
By default, the ViewHelper renders the record as-is. However, event listeners
can listen to the
\TYPO3\CMS\Fluid\Event\ModifyRenderedRecordEvent
to modify the output.
If you want to render a database record that has different
types, you can
use a TypoScript Content object array (COA)
to configure rendering for special types:
tx_myextension_domain_model_product = COA
tx_myextension_domain_model_product {
key {
field = my_type
}
default = FLUIDTEMPLATE
default {
templateName >
templateName.ifEmpty.cObject = TEXT
templateName.ifEmpty.cObject {
field = record_type
required = 1
case = uppercamelcase
}
# for record_type = 'mainProduct' the template file my_extension/Resources/Private/Templates/Product/MainProduct.html will be used
templateRootPaths.10 = EXT:my_extension/Resources/Private/Templates/Product/
layoutRootPaths.10 = EXT:my_extension/Resources/Private/Layouts/
partialRootPaths.10 = EXT:my_extension/Resources/Private/Partials/
dataProcessing.1421884800 = record-transformation
}
mySpecialType.templateRootPaths.20 = EXT:my_extension/Resources/Private/Templates/ProductSpecial/
}

\TYPO3\CMS\Fluid\Event\ModifyRenderedRecordEvent , developers can
intercept the rendering of individual records in Fluid templates to modify the
output.

Render.text ViewHelper <f:render.text>
New in version 14.2
This ViewHelper should be used whenever text fields from records are
displayed in HTML output. It can replace
{record.my_inputfield} for
input fields, as well as
<f:format.nl2br>{record.my_textarea}</f:format.nl2br>
and
<f:format.html>{record.my_richtext}</f:format.html>
ViewHelper to render content based on records and fields from a TCA schema. Handles the processing of both simple and rich text fields. By default, accessing a missing field raises an error. Set optional to true to return null instead.
Can also handle extbase models, you still need to provide the field name, not the property name.
The
<f:render.text> ViewHelper renders text-based fields from a record
according to their TCA configuration, automatically applying the correct formatting
(for example plain text, line breaks, or rich text).
It provides a unified way to render text fields and avoids manual formatting
logic in templates.
Use this ViewHelper when rendering fields defined in TCA.
Do not use it for:
Non-TCA properties
Computed or virtual model properties
The ViewHelper is record-aware: it receives the full record and the field name,
and renders the field based on its TCA configuration.
The record argument accepts:
RecordInterface
PageInformation
DomainObjectInterface
This includes records, ContentBlockData objects, page information objects,
and Extbase models.
The
field argument always refers to the database/TCA column name of the
underlying record, even if your Extbase model maps that column to a differently
named property.
Note that Extbase models need to contain all columns that should be rendered
and the record type column (if configured in TCA) for this to work correctly.
For example, an Extbase model that represents tt_content must map both bodytext
and ctype to be able to use
<f:render.text record="{contentModel}" field="bodytext" />.
For model properties that are not directly mapped to database / TCA fields,
use ViewHelpers like
<f:format.html>{myModel.mySpecialRichText}</f:format.html>
if formatting is required, or output them directly:
{record.mySpecialText} if no formatting is needed.
Arguments of the <f:render.text> ViewHelper

Security.nonce ViewHelper <f:security.nonce>
Changed in version 14.1, 13.4.23
CSP nonce sources set via the {f:security.nonce()} ViewHelper are no
longer incorrectly considered negligible. The newly introduced directive
and scope arguments allow TYPO3 to correctly assign that nonce to the
appropriate CSP directive, whereas previously the nonce could be silently
discarded due to missing context.
The {f:security.nonce()} ViewHelper generates a CSP
(Content Security Policy)
nonce and registers it for inclusion in the CSP header.
The optional arguments directive and scope can be used to explicitly
declare how the generated nonce should be applied to the Content Security
Policy. This avoids ambiguity and allows TYPO3 to assign the nonce to the
correct CSP directive.
Inline script (default scope)
Inline scripts require the nonce to be registered for the
script-src CSP directive. The inline scope is the default and may be
omitted.
Inline script with explicit directive
<scriptnonce="{f:security.nonce(directive: 'script-src')}">const test = true;
</script>
Copied!
External script (static scope)
When a nonce is applied to an external script, the static scope should
be used. This allows TYPO3 to correctly associate the nonce with a static
script element.

Uri.external ViewHelper <f:uri.external>
ViewHelper for creating URIs to external targets, enforcing a specific scheme (https by default). The specified URI is passed through without further resolving or transformation.
ViewHelper to resize, crop or convert a given image (if required) and return the URL to this processed file.
This ViewHelper should only be used for images within FAL storages, or where graphical operations shall be performed.
Note that when the contents of a non-FAL image are changed, an image may not show updated processed contents unless either the FAL record is updated/removed, or the temporary processed images are cleared.
Also note that image operations (cropping, scaling, converting) on non-FAL files may be changed in future TYPO3 versions, since those operations are coupled with FAL metadata. Each non-FAL image operation creates a "fake" FAL record, which may lead to problems.
For extension resource files, use <f:uri.resource> instead.
External URLs are not processed and just returned as is.

If you use the parameter only, then target, class and title will be discarded.
Declares new variables which are aliases of other variables.
Takes a "map"-Parameter which is an associative array which defines the shorthand mapping.
The variables are only declared inside the <f:alias>...</f:alias> tag. After the
closing tag, all declared variables are removed again.
Using this ViewHelper can be a sign of weak architecture. If you end up
using it extensively you might want to fine-tune your "view model" (the
data you assign to the view).
Examples
Single alias
<f:alias map="{x: 'foo'}">{x}</f:alias>
Copied!
Output:
foo
Copied!
Multiple mappings
<f:alias map="{x: foo.bar.baz, y: foo.bar.baz.name}">
{x.name} or {y}
</f:alias>
The following arguments are available for the alias ViewHelper:
map
map
Type
array
Required
1
Array that specifies which variables should be mapped to which alias
Argument ViewHelper <f:argument>
f:argument allows to define requirements and type constraints to variables that
are provided to templates and partials. This can be very helpful to document how
a template or partial is supposed to be used and which input variables are required.
These requirements are enforced during rendering of the template or partial:
If an argument is defined with this ViewHelper which isn't marked as optional,
an exception will be thrown if that variable isn't present during rendering.
If a variable doesn't match the specified type and can't be converted automatically,
an exception will be thrown as well.
Note that f:argument ViewHelpers must be used at the root level of the
template, and can't be nested into other ViewHelpers. Also, the usage of variables
in any of its arguments is not possible (e. g. you can't define an argument name
by using a variable).
Rendering of specific sections will not validate argument constraints. They
will only be evaluated if the template or partial is rendered directly.
<!-- All arguments supplied --><f:renderpartial="MyPartial"arguments="{title: 'My title', tags: {0: 'tag1', 1: 'tag2'}, user: 'me'}" /><!-- "user" will fall back to default value --><f:renderpartial="MyPartial"arguments="{title: 'My title', tags: {0: 'tag1', 1: 'tag2'}}" /><!-- "tags" will be "null", "user" will fall back to default value --><f:renderpartial="MyPartial"arguments="{title: 'My title'}" />
Copied!
The following render calls will result in an exception:
<!-- required "title" has not been supplied --><f:renderpartial="MyPartial" /><!-- "user" has been supplied as array, not as string --><f:renderpartial="MyPartial"arguments="{title: 'My title', user: {firstName: 'Jane', lastName: 'Doe'}}" />

Union Types
Changed in version Fluid 5.0
Union types are supported for component arguments.
An argument can allow multiple multiple types. In that case, the component's implementation
needs to make sure that all possible variants are considered. This should be used sparingly
since it can complicate the component's implementation code considerably.
the data to be used for rendering the cObject. Can be an object, array or string. If this argument is not set, child nodes will be used
table

Default
''
the table name associated with "data" argument. Typically tt_content or one of your custom tables. This argument should be set if rendering a FILES cObject where file references are used, or if the data argument is a database record.

Type
string
Required

Examples for the CObject ViewHelper <f:cObject>
The cObject ViewHelper can be used to render any TypoScript content object, for
example on stored in the lib
top-level object:
When passing an object with {data}, the properties of the object are
accessible with
.field in TypoScript. If only a single value is
passed or the currentValueKey is specified,
.current = 1
can be used in the TypoScript.
Use data from a TypoScript ContentObject
As an example of a more advanced use case, the cObject viewhelper can pass
content data from a Fluid template to a content object defined in TypoScript. The
following example demonstrates this with a user counter. The user counter is in
a blog post (the blog post has a count of how many times it has been viewed.)
Add the Viewhelper to your Fluid template. This can be done in 3 different
ways. The basic tag syntax:
Then, add TypoScript (to your TypoScript template) to process this data. In our
example below, the
stdWrap attribute
current
works like a switch: if set to 1, it contains the value that was passed to the
TypoScript object from the Fluid template:
Up till now, we have only been passing a single value to the TypoScript object.
However, it is also possible to pass multiple values, useful for selecting which value to
use or concatenating values, or you can pass objects (here the post object):
lib.myCounter = COA
lib.myCounter {
10 = TEXT10.field = title
20 = TEXT20.field = viewCount
wrap = (<strong>|</strong>)
}
Copied!
This TypoScript snippet outputs the title of the blog and the number of page visits in parentheses.
Using current to pass values
It is also possible to use the
current switch here.
If you set the property
currentValueKey
in the cObject ViewHelper, the value will be available in
the TypoScript template as
current. That is especially useful
when you want to emphasize that the value is very
important for the TypoScript template. For example, the
number of visits is significant in our view
counter:
Then, in the TypoScript template, use
field aswell as
current to output the value of the view count. The following
TypoScript snippet outputs the same information as above:
Variable {contentElement.mainType} already contains the correct TypoScript path
to the TypoScript top-level object tt_content.
The table storing the content elements is also called tt_content, so we can use
the same variable here. Variable contentElement will already contain the
Record object
containing the data needed to render the content element with the
CObject ViewHelper.
Comment ViewHelper <f:comment>
This ViewHelper prevents rendering of any content inside the tag.
Contents of the comment will not be parsed thus it can be used to
comment out invalid Fluid syntax or non-existent ViewHelpers during
development.
Using this ViewHelper won't have a notable effect on performance,
especially once the template is parsed. However, it can lead to reduced
readability. You can use layouts and partials to split a large template
into smaller parts. Using self-descriptive names for the partials can
make comments redundant.
Examples
Commenting out fluid code

Get class constant
You can display any public class constant from a class within TYPO3,
for example constants from
\TYPO3\CMS\Core\Information\Typo3Information :
Join the <f:link.externaluri="{f:constant(name: '\TYPO3\CMS\Core\Information\Typo3Information::URL_COMMUNITY')}">
TYPO3 Community
</f:link.external>!

Using enum cases in Fluid
Cases of enums are objects and not strings or integers. They cannot be directly
output in the template. You can however save them into a variable and
then use their value. For example you can use values of the enum cases in
\TYPO3\CMS\Core\Resource\FileType to compare them with a value of your
object:
<f:variablename="imageType"><f:constantname="\TYPO3\CMS\Core\Resource\FileType::IMAGE"/></f:variable>
The image case has the value {imageType.value} and name {imageType.name}:
<f:ifcondition="{myFile.type} === {imageType.value}">
This file is an image!

Fragment ViewHelper <f:fragment>
f:fragment is the counterpart of the <f:slot> ViewHelper.
It allows to provide multiple HTML fragments to a component, which defines
the matching named slots. f:fragment is used directly inside a component
tag, nesting into other ViewHelpers is not possible.
<my:textMediatitle="My title"><f:fragmentname="media"><imgsrc="path/to/image.jpg"alt="..." /></f:fragment><f:fragmentname="content"><p>My first paragraph</p><p>My second paragraph</p></f:fragment></my:textMedia>

If ViewHelper <f:if>
This ViewHelper implements an if/else condition.
Fluid Boolean Rules / Conditions:
A condition is evaluated as a boolean value, so you can use any
boolean argument, like a variable.
Alternatively, you can use a full boolean expression.
The entered expression is evaluated as a PHP expression. You can
combine multiple expressions via
&& (logical AND) and
|| (logical OR).
An expression can also be prepended with the
! ("not") character,
which will negate that expression.
Have a look into the Fluid section of the "TYPO3 Explained" Documentation
for more details about complex conditions.
Boolean expressions have the following form:
is true variant: {variable}:
<f:if condition="{foo}">
Will be shown if foo is truthy.
</f:if>
Copied!
or is false variant: !{variable}:
<f:if condition="!{foo}">
Will be shown if foo is falsy.
</f:if>
Copied!
or comparisons with expressions:
XX Comparator YY
Copied!
Comparator is one of:
==, !=, <, <=, >, >= and
%
The
% operator (modulo) converts the result of the operation to
boolean.
XX and YY can be one of:
Number
String
Object Accessor (object.property)
Array
a ViewHelper
<f:if condition="{rank} > 100">
Will be shown if rank is > 100
</f:if>
<f:if condition="{rank} % 2">
Will be shown if rank % 2 != 0.
</f:if>
<f:if condition="{rank} == {k:bar()}">
Checks if rank is equal to the result of the ViewHelper "k:bar"
</f:if>
<f:if condition="{object.property} == 'stringToCompare'">
Will result in true if {object.property}'s represented value
equals 'stringToCompare'.
</f:if>

Image ViewHelper <f:image>
ViewHelper to resize, crop or convert a given image (if required) and render the corresponding HTML <img> tag showing the processed image.
Note that image operations (cropping, scaling, converting) on non-FAL files (i.e. extension resources) may be changed in future TYPO3 versions, since those operations are coupled with FAL metadata. Each non-FAL image operation creates a "fake" FAL record, which may lead to problems.
Argument src - displaying images from extension assets
Images used for design purposes and not content purposes are commonly shipped
in an extension. These images cannot be edited by backend users. They can be
displayed using the <f:image> ViewHelper using the
src
argument and EXT: syntax:
In the extension the assets must be stored under Resources/Public/ or
a subfolder of this folder.
If you installed the extension via Composer before it had a folder of that
exact name, reinstall it so that the symlinks in folder public/_assets
are correctly created for you.
Note
Avoid using image operations such as the arguments
width or
crop
with images included from an extensions' assets. Each
non-FAL image operation creates a "fake" FAL record, which may lead to problems.
Argument image - display images from the folder fileadmin / from FAL
For example, if you want to display an image that is attached to a content
element, the content element typically stores a reference count of attached images in
its media field. Intermediate tables are then used to attach the actual image
to the content elements. This allows backend users to move or rename files,
without the files connection being lost in the content element.
This allows integrators to globally define which output format TYPO3 should
use when converting images, for example, to prefer WebP output for JPEG and
GIF sources by default.
The FAL will scale the image and
convert it to a web format if necessary (for example from a pdf to a png).
The <f:image> ViewHelper generates a HTML <img> tag with the correct paths, etc.
Images from Extbase models in Fluid
In Extbase models you can use fields of type
\TYPO3\CMS\Extbase\Persistence\ObjectStorage with
the TCA type File.
When you are looping through the object storage, each element will be of type
\TYPO3\CMS\Extbase\Domain\Model\FileReference . They can be used with the
image
argument:
If you have the UID of the sys_file_reference table (preferred) you have to set
treatIdAsReference
to true and pass the UID of the file reference to the
src
argument.
If only the UID of the sys_file table is available, you can pass this value to
the src
argument of the ViewHelper and treatIdAsReference can be kept as the default value (false).
In this case no data from the file reference, such as default cropping or overrides for alt text and
description, will be available.
<f:imagesrc="{reference.uid}"treatIdAsReference="1"height="250"/><f:imagesrc="{file.uid}"height="250"alt="My image description"/><!-- File with uid 42 --><f:imagesrc="42"treatIdAsReference="1"class="something"height="250"/>
Copied!
Displaying an image using its typolink string
If the file is configured as a typolink, for example from a TCA field of type
Link, you can use
the typolink string, starting with t3://file, as
src:
<f:imagesrc="{file.link}"height="250"/><!-- File with uid 928 --><f:imagesrc="t3://file?uid=928"height="250"/>

Embedding SVG files with the base64 attribute
When the base64
argument is set to true, the resulting image tag will contain the source of the image in a base64
encoded form.
This can be particularly useful inside
FluidEmail
or to prevent unnecessary HTTP calls.

Inline ViewHelper <f:inline>
Inline Fluid rendering ViewHelper
Renders Fluid code stored in a variable, which you normally would
have to render before assigning it to the view. Instead you can
do the following (note, extremely simplified use case):
$view->assign('variable', 'value of my variable');
$view->assign('code', 'My variable: {variable}');
Copied!
And in the template:
{code -> f:inline()}
Copied!
Which outputs:
My variable: value of my variable
Copied!
You can use this to pass smaller and dynamic pieces of Fluid code
to templates, as an alternative to creating new partial templates.
The following arguments are available for the inline ViewHelper:
code

Fluid code to be rendered as if it were part of the template rendering it. Can be passed as inline argument or tag content
Join ViewHelper <f:join>
The JoinViewHelper combines elements from an array into a single string.
You can specify both a general separator and a special one for the last
element, which serves as the delimiter between the elements.
The following arguments are available for the max ViewHelper:
value

Media ViewHelper <f:media>
ViewHelper to render a given media file (audio/video/images) with the correct HTML tag.
It utilizes the RendererRegistry to determine the correct Renderer class. When no renderer can be resolved, it will fall back to use the default ImageViewHelper for regular images.
This ViewHelper allows you to pass arbitrary arguments not defined below directly
to the HTML tag created. This includes custom
data- arguments.

During rendering the content of file
packages/my_site_package/Resources/Private/PageView/Partials/Footer.html
will be rendered with all variables that are also available in the main template.
It is possible to render a partial within a partial or layout as well. For
example the footer partial could look like this:
When the argument partial
contains a slash / the partial will be searched in a subfolder. The partial
from the above example will therefore be expected in file
packages/my_site_package/Resources/Private/PageView/Partials/Navigation/FooterMenu.html.
Configuring the path in which to save the partials
Partials used to display pages with the TypoScript object
PAGEVIEW are
always found in folder Partials within the path that has been defined in
property paths.[priority].
Partials used to display content elements or pages using the TypoScript
object FLUIDTEMPLATE
are searched in the paths defined in property
partialRootPaths.
If the section is rendered from within a layout file the section can be defined
in the template using the layout. Since usually several templates use the same
layout, it can be helpful to mark the render tag as

It is also possible to provide a default value to be displayed if the section
was not found in the template. You can use the content of the tag or the argument
default.

Replace ViewHelper <f:replace>
The ReplaceViewHelper replaces one or multiple strings with other
strings. This ViewHelper mimicks PHP's
str_replace() function.
However, it's also possible to provide replace pairs as associative array
via the "replace" argument.
The following arguments are available for the shuffle ViewHelper:
value

Type

Slot ViewHelper <f:slot>
f:slot allows a template that is called as a component to access and render
the child content of the calling component tag. This makes nesting of components
possible.
Most importantly, the f:slot ViewHelper makes sure that the right level of
HTML escaping happens automatically, in line with the escaping in other parts of
Fluid: If HTML is used directly, it is not escaped. However, if a variable is
used within the child content that contains a HTML string, that HTML is escaped
because it might be from an unknown source.
In combination with the <f:fragment> ViewHelper,
multiple slots can be used in one component.
If a slot is defined, this ViewHelper will always attempt to return a string,
regardless of the original type of the content. If a slot is not defined, the
ViewHelper will return null.
<my:texttitle="My title"><p>My first paragraph</p><p>My second paragraph</p></my:text>
Copied!
it will result in the following output:
<divclass="textComponent"><h2>My title</h2><divclass="textComponent__content"><p>My first paragraph</p><p>My second paragraph</p></div></div>
Copied!
Escaping Example
If the same component is called like this:
<f:variablename="htmlString"><p>My first paragraph</p><p>My second paragraph</p></f:variable><my:texttitle="My title">{htmlString}</my:text>
Copied!
it would result in escaped HTML:
<divclass="textComponent"><h2>My title</h2><divclass="textComponent__content"><p>My first paragraph</p><p>My second paragraph</p></div></div>
Copied!
If you want to avoid escaping in this use case, you need to use f:format.raw on
the variable when it's passed to the component. Please be aware that depending on
the source of the input, this might have security implications!
Component Nesting Example
Nesting of multiple components is possible. The following template Paragraphs.html:
<p>My first paragraph</p><p>My second paragraph</p>
Copied!
can be called as a component and nested into the text component described above:
<my:textMediatitle="My title"><f:fragmentname="media"><imgsrc="path/to/image.jpg"alt="..." /></f:fragment><f:fragmentname="content"><p>My first paragraph</p><p>My second paragraph</p></f:fragment></my:textMedia>
Copied!
it will result in the following output:
<divclass="textMediaComponent"><h2>My title</h2><divclass="textMediaComponent__media"><imgsrc="path/to/image.jpg"alt="..." /></div><divclass="textMediaComponent__content"><p>My first paragraph</p><p>My second paragraph</p></div></div>
The SplitViewHelper splits a string by the specified separator, which
results in an array. The number of values in the resulting array can
be limited with the limit parameter, which results in an array where
the last item contains the remaining unsplit string.
This ViewHelper mimicks PHP's
explode() function.
The following examples store the result in a variable because an array cannot
be outputted directly in a template.
The following arguments are available for the split ViewHelper:
limit
limit
Type
int
Default
9223372036854775807
If limit is positive, a maximum of $limit items will be returned. If limit is negative, all items except for the last $limit items will be returned. 0 will be treated as 1.

StartsWith ViewHelper <f:startsWith>
StartsWith ViewHelper checks if the subject string starts with a specified string.
This ViewHelper implements an if/else condition.
Examples
Render the body if "myString" starts with "Hello"
<f:variable name="myString" value="Hello, World!" />
<f:startsWith search="Hello" subject="{myString}">This will be rendered if variable "myString" starts with "Hello"</f:startsWith>

Switch ViewHelper <f:switch>
Switch ViewHelper which can be used to render content depending on a value or expression.
Implements what a basic PHP switch() does.
An optional default case can be specified which is rendered if none of the
case conditions matches.
Using this ViewHelper can be a sign of weak architecture. If you end up using it extensively
you might want to consider restructuring your controllers/actions and/or use partials and sections.
E.g. the above example could be achieved with
<f:render partial="title.{person.gender}" />
and the partials "title.male.html", "title.female.html", ...
Depending on the scenario this can be easier to extend and possibly contains less duplication.
ViewHelper to provide a translation for language keys ("locallang"/"LLL"). By default, the files are loaded from the folder Resources/Private/Language/.
The translate ViewHelper supports translation domains,
a short and convenient way to reference language labels without
requiring LLL: paths or extension names.
Translation domain syntax is the recommended and future-proof way
to reference translations.
The older LLL: and extension arguments are still valid for
backward compatibility.
All existing syntax remains fully supported, ensuring backward
compatibility. The new syntax can be adopted incrementally within a
project, and both old and new forms can coexist in the same template.
Using translation domains
The translation domain syntax is the recommended way to
reference labels. It allows concise and clear label identifiers, without using
LLL: paths and extension names.
There are two equivalent ways to use domains:
Provide the domain as a separate argument and only reference the identifier
(recommended):
Alternatively, you can use id instead of key to produce the same output.
If both id and key are set, id takes precedence.
If the translate ViewHelper is used with only the language key, the template
must be rendered in an Extbase request, usually from an Extbase
controller action. The default language file must be located in the same
extension as the Extbase controller and must be saved in
Resources/Private/Language/locallang.xlf.
Short key and extension name
If the ViewHelper is called from outside Extbase, the extension name or the
full LLL: key reference must be passed as arguments.

Warning
When allowing HTML tags in translations, ensure all translators are
educated about Cross-site scripting (XSS).
Displaying translated labels with placeholders
<f:translatedomain="my_extension.domainmodel"key="title"arguments="{0: '{myVariable}'}"

Copied!
The placeholder %s is used to insert dynamic values, passed as the parameter
arguments
to the translate ViewHelper. If %s appears multiple times, it references
subsequent array entries in order.
To avoid dependency on order, use indexed placeholders like %1$s. This
explicitly refers to the first value and ensures that it is treated as a string
($s). This method is based on PHP’s
vsprintf function,
which allows for more flexible and readable formatting.
Inline notation with arguments and default value
Like all the other ViewHelpers, the translate ViewHelper can be used with
Inline syntax.
The translation ViewHelper determines the target language based on the current
frontend or backend request.
If you are rendering your template from a console/CLI context, for example,
when you Send emails with FluidEmail,
use the argument languageKey
to specify the desired language for the ViewHelper:
Salutation in Danish:
<f:translatedomain="my_extension.messages"key="salutation"languageKey="da"
/>
Salutation in English:
<f:translatedomain="my_extension.messages"key="salutation"languageKey="default"
/>
