typolink

Wraps the incoming value in a link with an HTML 'a' tag.

If you do not want to have the HTML 'a' tag around the link, then you must set the property by returnLast = url or $lconf['returnLast'] = 'url'.

Important

If this is used from parseFunc the $cObj->parameters array is loaded with the lowercased link-parameters!

Properties

extTarget

Property: extTarget
Data type: target / stdWrap
Description: Target used for external links
Default: _top

fileTarget

Property: fileTarget
Data type: target / stdWrap
Description: Target used for file links

language

Property

language

Data type

integer

Description

Language uid for link target

Omitting the parameter language will use the current language.

Example

page.10 = TEXT
page.10.value = Link to the page with the ID 23 in the current language
page.10.typolink.parameter = 23
page.20 = TEXT
page.20.value = Link to the page with the ID 23 in the language 3
page.20.typolink.parameter = 23
page.20.typolink.language = 3

target

Property: target
Data type: target / stdWrap
Description: Target used for internal links

no_cache

Property: no_cache
Data type: boolean / stdWrap
Description: Adds &no_cache=1 to the link

additionalParams

Property

additionalParams

Data type

string / stdWrap

Description

This is parameters that are added to the end of the URL. This must be code ready to insert after the last parameter.

Example

EXT:site_package/Configuration/TypoScript/setup.typoscript

page.10.typolink.additionalParams = '&print=1'
page.20.typolink.additionalParams = '&sword_list[]=word1&sword_list[]=word2'

Applications

This is very useful – for example – when linking to pages from a search result. The search words are stored in the register-key SWORD_PARAMS and can be insert directly like this:

EXT:site_package/Configuration/TypoScript/setup.typoscript

page.20.typolink.additionalParams.data = register:SWORD_PARAMS

Note

This is only active for internal links.

addQueryString

Property

addQueryString

Data type

boolean

Description

Add the current query string to the start of the link.

Note

This option does not check for any duplicate parameters! This is not a problem: Only the last parameter of the same name will be applied.

.exclude: List of query arguments to exclude from the link. Typical examples are 'L' or 'cHash'.

Attention

This property should not be used for cached contents without a valid cHash. Otherwise the page is cached for the first set of parameters and subsequently taken from the cache no matter what parameters are given. Additionally the security risk of cache poisoning has to be considered.

Example

# Pass all GET parameters to the link
typolink.addQueryString = 1

# Remove parameter "gclid" from query string
typolink.addQueryString.exclude = gclid

wrap

Property: wrap
Data type: wrap / stdWrap
Description: Wraps the links.

ATagBeforeWrap

Property: ATagBeforeWrap
Data type: boolean
Description: If set, the link is first wrapped with wrap and then the <A>-tag.
Default: 0

parameter

Property

parameter

Data type

string / stdWrap

Description

This is the main data that is used for creating the link. It can be the id of a page, the URL of some external page, an email address or a reference to a file on the server. On top of this there can be additional information for specifying a target, a class and a title. Below are a few examples followed by full explanations.

Examples

Most simple. Will create a link to page 51 (if this is not default language, the correct target language will be resolved from the parameter):

EXT:site_package/Configuration/TypoScript/setup.typoscript
```
page.10.typolink.parameter = t3://page?uid=51
```
Copied!
A full example. A link to the current page that will open in a new window. The link will have a class attribute with value "specialLink" and a title attribute reading "Very important information":

EXT:site_package/Configuration/TypoScript/setup.typoscript
```
page.10.typolink.parameter = t3://page?uid=current _blank specialLink "Very important information"
```
Copied!
which is converted to a link like this:

Example output
```
<a href="?id=51" target="_blank" class="specialLink" title="Very important information">
```
Copied!
An external link with a class attribute. Note the dash (-) that replaces the second value (the target). This makes it possible to define a class (third value) without having to define a target:

EXT:site_package/Configuration/TypoScript/setup.typoscript
```
page.10.typolink.parameter = https://example.com/ - specialLink
```
Copied!
A mailto link with a title attribute (but no target and no class):

EXT:site_package/Configuration/TypoScript/setup.typoscript
```
page.10.typolink.parameter = mailto:info@example.org - - "Send a mail to main TYPO3 contact"
```
Copied!

As you can see from the examples, each significant part of the parameter string is separated by a space. Values that can themselves contain spaces must be enclosed in double quotes. Each of these values are described in more detail below.

Link targets that are external or contain _blank will be added rel="noreferrer" automatically.

Resource reference

The link

The first value is the destination of the link. It may start with:
- t3://: internal TYPO3 resource references. See Resource references for an in depth explanation on the syntax of these references.
- http(s)://: regular external links
- mailto:info@example.org: regular mailto links
It's also possible to direct the typolink to use a custom function (a "link handler") to build the link. This is described in more detail below.
Target or popup settings

Targets are normally as described above (extTarget, fileTarget, target). But it is possible to override them by explicitly defining a target in the parameter property. It's possible to use a dash (-) to skip this value when one wants to define a third or fourth value, but no target.

Instead of a target, this second value can be used to define the parameters of a JavaScript popup window into which the link will be opened (using window.open). The height and width of the window can be defined, as well as additional parameters to be passed to the JavaScript function. Also see property "Jswindow".
Examples
Open page 51 in a popup window measuring 400 by 300 pixels:

EXT:site_package/Configuration/TypoScript/setup.typoscript
```
typolink.parameter = 51 400x300
```
Copied!
Open page 51 in a popup window measuring 400 by 300 pixels. Do not make the window resizable and show the location bar:

EXT:site_package/Configuration/TypoScript/setup.typoscript
```
typolink.parameter = 51 400x300:resizable=0,location=1
```
Copied!
Class

The third value can be used to define a class name for the link tag. This class is inserted in the tag before any other value from the "ATagParams" property. Beware of conflicting class attributes. It's possible to use a dash (-) to skip this value when one wants to define a fourth value, but no class (see examples above).
Title

The standard way of defining the title attribute of the link would be to use the title property or even the ATagParams property. However it can also be set in this fourth value, in which case it will override the other settings. Note that the title should be wrapped in double quotes (") if it contains blanks.

Attention: When used from parseFunc, the value should not be defined explicitly, but imported like this:

EXT:site_package/Configuration/TypoScript/setup.typoscript
```
typolink.parameter.data = parameters : allParams
```
Copied!

forceAbsoluteUrl

Property

forceAbsoluteUrl

Data type

boolean

Description

Forces links to internal pages to be absolute, thus having a proper URL scheme and domain prepended.

Additional sub-property:

.scheme

Defines the URL scheme to be used (https or http). http is the default value. Example:

EXT:site_package/Configuration/TypoScript/setup.typoscript

typolink {
   parameter = 13
   forceAbsoluteUrl = 1
   forceAbsoluteUrl.scheme = https
}

Default

0

title

Property: title
Data type: string / stdWrap
Description: Sets the title parameter of the A-tag.

JSwindow_params

Property

JSwindow_params

Data type

string

Description

Preset values for opening the window. This example lists almost all possible attributes:

EXT:site_package/Configuration/TypoScript/setup.typoscript

page.10.typolink.JSwindow_params = status=1,menubar=1,scrollbars=1,resizable=1,location=1,directories=1,toolbar=1

returnLast

Property

returnLast

Data type

string

Description

If set to "url", then it will return the URL of the link ($this->lastTypoLinkUrl).

If set to target, it will return the target of the link.

So, in these two cases you will not get the value wrapped but the URL or target value returned!

New in version 11.4

If set to result, it will return the json_encoded output of the internal LinkResult object.
{
    "href": "/my-page",
    "target": null,
    "class": null,
    "title": null,
    "linkText": "My page",
    "additionalAttributes": []
}
Copied!

section

Property

section

Data type

string / stdWrap

Description

If this value is present, it's prepended with a "#" and placed after any internal URL to another page in TYPO3.

This is used create a link, which jumps from one page directly the section on another page.

ATagParams

Property

ATagParams

Data type

<A>-params / stdWrap

Description

Additional parameters

Example

EXT:site_package/Configuration/TypoScript/setup.typoscript

page.10.typolink.ATagParams = class="board"

linkAccessRestrictedPages

Property: linkAccessRestrictedPages
Data type: boolean
Description: If set, typolinks pointing to access restricted pages will still link to the page even though the page cannot be accessed.

userFunc

Property

userFunc

Data type

function name

Description

This passes the link-data compiled by the typolink function to a user- defined function for final manipulation.

The $content variable passed to the user-function (first parameter) is an array with the keys "TYPE", "TAG", "url", "targetParams" and "aTagParams".

TYPE is an indication of link-kind: mailto, url, file, page

TAG is the full <A>-tag as generated and ready from the typolink function.

The actual tag value is constructed like this:

$contents = '<a href="' . $finalTagParts['url'] . '"'
            . $finalTagParts['targetParams']
            . $finalTagParts['aTagParams'] . '>';

The userfunction must return an <A>-tag.

Resource references

TYPO3 supports a modern and future-proof way of referencing resources using an extensible and expressive syntax.

In order to understand the syntax, we will guide you through using a simple page link.

t3://page?uid=13&campaignCode=ABC123

The syntax consists of three main parts, much like parts on an URL:

Syntax Namespace (t3://)

The namespace is set to t3:// to ensure the LinkService should be called to parse the URL. This value is fixed and mandatory.

Resource handler key (page)

The resource handler key is a list of available handlers that TYPO3 can work with. At the time of writing these handlers are:

'page' (see \TYPO3\CMS\Core\LinkHandling\PageLinkHandler )
'file' (see \TYPO3\CMS\Core\LinkHandling\FileLinkHandler )
'folder' (see \TYPO3\CMS\Core\LinkHandling\FolderLinkHandler )
'url' (see \TYPO3\CMS\Core\LinkHandling\UrlLinkHandler )
'email' (see \TYPO3\CMS\Core\LinkHandling\EmailLinkHandler )
'record' (see \TYPO3\CMS\Core\LinkHandling\RecordLinkHandler )
'telephone' (see \TYPO3\CMS\Core\LinkHandling\TelephoneLinkHandler )

More keys can be added via $GLOBALS['TYPO3_CONF_VARS']['SYS']['linkHandler'] in an associative array where the key is the handler key and the value is a class implementing the LinkHandlerInterface.

Resource parameters (?uid=13&campaignCode=ABC123)

These are the specific identification parameters that are used by any handler. Note that these may carry additional parameters in order to configure the behavior of any handler.

Handler syntax

page

The page identifier is a compound string based on several optional settings.

uid (int|string):

The uid of a page record, or "current" to reference the current page.

t3://page?uid=13

t3://page?uid=current

alias (string):

The alias of a page record (as an alternative to the UID).

t3://page?alias=myfunkyalias

type (int) (optional):

t3://page?uid=13&type=3 will reference page 13 in type 3.

parameters (string) (optional, prefixed with &):

t3://page?uid=1313&my=param&will=get&added=here

fragment (string) (optional, prefixed with #):

t3://page?alias=myfunkyalias#c123

t3://page?uid=13&type=3#c123

t3://page?uid=13&type=3&my=param&will=get&added=here#c123

file

uid (int):

The UID of a file within the FAL database table sys_file.

t3://file?uid=13

identifier (string):

The identifier of a file using combined <storage>:<path> reference or a direct reference to one file like fileadmin/path/myfile.jpg.

t3://file?identifier=1:/path/myfile.jpg

t3://file?identifier=fileadmin/path/myfile.jpg

folder

identifier (string):

The identifier of a given folder.

t3://folder?identifier=fileadmin

storage (string) (optional):

The FAL storage to the given folder.

t3://folder?storage=1&identifier=myfolder

email

email (string):

Mail address to be used, prefixed with mailto:

t3://email?email=mailto:user@example.org

url

url (string):

URL to be used, if no scheme is used http:// is prefixed automatically. Query parameters have to be URL-encoded.

t3://url?url=example.org

t3://url?url=https://example.org

t3://url?url=https://example.org%26parameter=value

record

Aspects identifier and uid are mandatory for this link handler.

identifier (string):

The (individual) identifier of the link building configuration to be used.

uid (int):

The UID of the referenced record to be linked.

Example

The following reference relates to record tx_myextension_content:123. Tablename is retrieved from Page TSconfig settings, actual link generation is defined in TypoScript configuration for identifier my_content.

t3://record?identifier=my_content&uid=123

Page TSconfig definition for identifier my_content

TCEMAIN.linkHandler.my_content {
    handler = TYPO3\CMS\Recordlist\LinkHandler\RecordLinkHandler
    label = LLL:EXT:my_extension/Resources/Private/Language/locallang.xlf:link.customTab
    configuration {
        table = tx_myextension_content
    }
    scanBefore = page
}

Frontend TypoScript definition for identifier my_content

config.recordLinks.my_content {
    // Do not force link generation when the record is hidden
    forceLink = 0

    typolink {
        // pages.uid to be used to render result (basically it contains the rendering plugin)
        parameter = 234
        // field values of tx_myextension_content record with uid 123
        additionalParams.data = field:uid
        additionalParams.wrap = &tx_myextension[uid]= | &tx_myextension[action]=show
    }
}

Examples

Create a link to page with uid 2:

EXT:site_package/Configuration/TypoScript/setup.typoscript

page.20 = TEXT
page.20.value = anchor text
page.20.typolink.parameter = 2

Output:

Example output

<a href="/somepage">anchor text</a>

Just display the URL:

EXT:site_package/Configuration/TypoScript/setup.typoscript

page.30 = TEXT
page.30.typolink.parameter = 2
page.30.typolink.returnLast = url

Output:

Example output

/somepage
