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.
Arguments of the <f:asset.css> 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.

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 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: 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.

It is considered best practice to use the states from
\TYPO3\CMS\Fluid\ViewHelpers\Be\InfoboxViewHelper
together with the
Constant ViewHelper <f:constant>:
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.
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!
ViewHelper to insert variables which only apply during
cache warmup and only apply if no other variables are
specified for the warmup process.
If a chunk of template code is impossible to compile
without additional variables, for example when rendering
sections or partials using dynamic names, you can use this
ViewHelper around that chunk and specify a set of variables
which will be assigned only while compiling the template
and only when this is done as part of cache warmup. The
template chunk can then be compiled using those default
variables.
This does not imply that only those variable values will
be used by the compiled template. It only means that
DEFAULT values of vital variables will be present during
compiling.
If you find yourself completely unable to properly warm up
a specific template file even with use of this ViewHelper,
then you can consider using
f:cache.disable ViewHelper
to prevent the template compiler from even attempting to
compile it.
USE WITH CARE! SOME EDGE CASES OF FOR EXAMPLE VIEWHELPERS
WHICH REQUIRE SPECIAL VARIABLE TYPES MAY NOT BE SUPPORTED
HERE DUE TO THE RUDIMENTARY NATURE OF VARIABLES YOU DEFINE.
Examples
Usage and effect
<f:cache.warmup variables="{foo: bar}">
Template code depending on {foo} variable which is not
assigned when warming up Fluid's caches. {foo} is only
assigned if the variable does not already exist and the
assignment only happens if Fluid is in warmup mode.
</f:cache.warmup>

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,
',',
);
}
}
}

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>

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.

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"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>

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"

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.

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.
If you use TypoScript properties such as
field
or
dataWrap
,
you should pass the current record as data. This ensures that field references like
{FIELD:title} are resolved correctly.
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
<br />
.
The <f:format.nl2br> ViewHelper uses PHP's
nl2br() function
to insert HTML line breaks.
Optionally, the stripped characters can also be specified using the characters parameter. Simply list all characters that you want to be stripped. With .. you can specify a range of characters.

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.image ViewHelper <f:uri.image>
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.
This can be particularly useful inside FluidEmail or to prevent unneeded HTTP calls.

Alias ViewHelper <f:alias>
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).
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.

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:
lib.someLibObject = TEXT
lib.someLibObject.value = Hello World!
Copied!
Displaying content elements provided by the page-content data processor
When using the page-content data processor
to display the content elements of a
PAGEVIEW,
the CObject ViewHelper can be used to display the actual content elements:
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 already contains the
Record object
containing the data needed to render the content element with the
CObject ViewHelper.
Use data from a plugin in TypoScript
By using the data property you can forward data provided by the controller
to the TypoScript object doing the actual rendering:
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:
lib.myCounter = COA
lib.myCounter {
10 = TEXT10.field = title
20 = TEXT20.current = 1
wrap = (<strong>|</strong>)
}
Copied!
Using
current
makes the TypoScript easier to read and the logic
easier to understand.
In summary, the cObject ViewHelper is a powerful option to embed TypoScript
expressions in Fluid templates.
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.

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>!
Copied!
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!
</f:if>
Copied!

Debug ViewHelper <f:debug>
ViewHelper to generate an HTML readable dump of variables or objects. The output can be navigated like a nested tree. The output will be put at the beginning of the HTML response, unless the inline attribute is set, so that the output will be placed at the specific place where it is placed inside a Fluid template.
If you want to display the flash messages in any place outside of the controller
you can use the identifier extbase.flashmessages.<pluginNamespace>, for example:
The name of the variable to store iteration information (index, cycle, total, isFirst, isLast, isEven, isOdd)

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.
Grouped loop ViewHelper.
Loops through the specified values.
The groupBy argument also supports property paths.
Using this ViewHelper can be a sign of weak architecture. If you end up

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.
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.
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.
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.
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.

Merge ViewHelper <f:merge>
The MergeViewHelper merges two arrays into one, optionally recursively.
It works similar to the PHP functions array_merge() and array_merge_recursive(),
depending on the value of the "recursive" argument.
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
optional.
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.
<f:layoutname="PageLayout"/><f:sectionname="Header"><header>My Special header</header></f:section><f:sectionname="Breadcrumb"><f:renderpartial="Navigation/Breadcrumb"arguments="{_all}"></f:section><f:sectionname="Main"><main>Main content of Template 1</main></f:section>

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.
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.
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.
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.
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/. Placeholder substitution (like PHP's sprintf()) can be evaluated when provided as arguments attribute.
Alternatively, you can use id instead of key, producing 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 within 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 the file
Resources/Private/Language/locallang.xlf.
Short key and extension name
When the ViewHelper is called from outside Extbase, it is mandatory to either
pass the extension name or use the full LLL: reference for the key.

The entry in the .xlf language file must be surrounded by <![CDATA[...]]>.
Warning
When allowing HTML tags in translations, ensure all translators are
educated about Cross-site scripting (XSS).
<f:translatekey="LLL:EXT:my_extension/Resources/Private/Language/locallang.xlf:domain_model.title"arguments="{0: '{myVariable}'}"
/>
Or with several numbered placeholders:
<f:translatekey="LLL:EXT:my_extension/Resources/Private/Language/locallang.xlf:domain_model.title"arguments="{1: '{myVariable}', 2: 'Some String'}"
/>
<?xml version="1.0" encoding="UTF-8" ?><xliffversion="1.2"xmlns="urn:oasis:names:tc:xliff:document:1.2"><filesource-language="en"datatype="plaintext"original="EXT:my_extension/Resources/Private/Language/locallang.xlf"date="2020-10-18T18:20:51Z"product-name="my_extension"

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 <https://www.php.net/manual/en/function.vsprintf.php>,
which allows for more flexible and readable formatting.
Inline notation with arguments and default value
Like all other ViewHelpers, the translate ViewHelper can be used with the
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:translatekey="LLL:EXT:my_extension/Resources/Private/Language/my_locallang.xlf:salutation"languageKey="da"
/>
Salutation in English:
<f:translatekey="LLL:EXT:my_extension/Resources/Private/Language/my_locallang.xlf:salutation"languageKey="default"
/>

Use this ViewHelper to provide a link to the official documentation. The ViewHelper will
use the permalink identifier to generate a permalink to the documentation which is
a redirect to the actual URI.
The identifier must be given as a string. Be aware that very specific short links into
the documentation may change over time.
The link will always lead to the documentation of the corresponding TYPO3 version. This
means in a v12 installation, using foo-bar as identifier will link to 'foo-bar@12.4',
while in v13 the link will be 'foo-bar@13.4'.

Contributions to this manual are made by editing the ViewHelper's page in
the TYPO3CMS-Reference-ViewHelper repository —
the usual Edit on GitHub workflow works as it does in every other official
TYPO3 manual. Use the Edit on GitHub button on the page you want
to change.
Which parts of a page are generated
Every ViewHelper page mixes two kinds of content:
Generated
The description, flags such as deprecated or internal, and the table
of arguments all come from the ViewHelper's PHP class. The
typo3:viewhelper
directive reads them from
Documentation/Global.json and the other JSON files each time the
manual is rendered. The Fluid ViewHelper Documentation Generator
keeps those files current, running once a day. A change to a doc-comment
or to an argument therefore appears on the page without anyone editing
it.
Written by hand
Everything else: the explanations, the examples and the structure of the
page. This is what you contribute.
Pages are only ever added, never rewritten:
A ViewHelper that has no page yet gets one from the generator — once.
An existing page is never overwritten, so hand-written text is safe.
When a ViewHelper is removed from the TYPO3 Core, its page is left
behind and has to be deleted by hand.
Hand-written documentation is preferred
Extended examples belong on the page in this manual, not in the PHP
doc-comment. A doc-comment should stay a short description of what the
ViewHelper does. Longer explanations, several usage examples and their
rendered output are easier to read and to maintain in the manual, where they
can use the full reST markup, tabs and literal includes.
Recommended page structure
See Documentation/Global/Form/Checkbox.rst for a page that follows
this structure:
A
:navigation-title:
and an anchor, followed by the page title.
The
typo3:viewhelper
directive showing the description and flags:
Editing the PHP doc-comment is the right fix when the short description
itself is wrong or missing, since that text is shown on the page and in
IDEs. The ViewHelper classes live at
Such a change reaches this manual with the next run of the generator, which
happens once a day. See
Fluid ViewHelper reference generation
for how the whole process fits together.
You can use the common directives of the
reST markup language supported by the TYPO3 documentation rendering
toolchain.
