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!

Examples¶

Create a link to page with uid 2:

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

Output:

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

Just display the URL:

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

Output:

/somepage

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

useCacheHash¶

Property
useCacheHash
Data type
boolean
Description

If set, the additionalParams list is exploded and calculated into a hash string appended to the URL, like “&cHash=ae83fd7s87”. When the caching mechanism sees this value, it calculates the same value on the server based on incoming values in HTTP_GET_VARS, excluding id, type, no_cache, ftu, cHash, MP values. If the incoming cHash value matches the calculated value, the page may be cached based on this.

The $GLOBALS['TYPO3_CONF_VARS']['SYS']['encryptionKey'] is included in the hash in order to make it unique for the server and non-predictable.

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
'&print=1'
'&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:

.additionalParams.data = register:SWORD_PARAMS

Note: This is only active for internal links.

addQueryString¶

Property
addQueryString
Data type
boolean
Description

Add the QUERY_STRING to the start of the link. Notice that this does not check for any duplicate parameters! This is not a problem: Only the last parameter of the same name will be applied.

.method

If set to GET or POST, then the parsed query arguments (GET or POST data) will be used. This setting is useful, if you use URL processing extensions like Real URL, which translate part of the path into query arguments.

It’s also possible to get both, POST and GET data, on setting this to

“POST,GET” or “GET,POST”. The last method in this sequence takes precedence and overwrites the parts that are also present for the first method.

.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 subsubsequently taken from the cache no matter what parameters are given. Additionally the security risk of cache poisoning has to be considered.

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
  1. 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):

    parameter = t3://page?uid=51
    
  2. A full example. A link to page 51 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”:

    parameter = t3://page?uid=51 _blank specialLink "Very important information"
    
  3. which is converted to a link like this:

    <a href="?id=51" target="_blank" class="specialLink" title="Very important information">
    
  4. 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:

    parameter = https://example.com/ - specialLink
    
  5. A mailto link with a title attribute (but no target and no class):

    parameter = mailto:info@example.org - - "Send a mail to main TYPO3 contact"
    

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.

Resource reference
  1. 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.

  2. 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:

    typolink.parameter = 51 400x300
    

    Open page 51 in a popup window measuring 400 by 300 pixels. Do not make the window resizable and show the location bar:

    typolink.parameter = 51 400x300:resizable=0,location=1
    
  3. 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).

  4. 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:

    typolink.parameter.data = parameters : allParams
    

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:

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:

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!

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:

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 which is easy to understand.

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
  • file
  • folder
  • email
  • url
  • record

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):

The uid of a page record.

t3://page?uid=13

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
        useCacheHash = 1
    }
}

Using link handlers¶

A feature allows you to register a link handler for a keyword you define. For example, you can link to a page with id 34 with “<link 34>” in a typical bodytext field which converts <link> tags with “->typolink”. But what if you have an extension, “pressrelease”, and wanted to link to a press release item displayed by a plugin on some page you don’t remember? With this feature it’s possible to create the logic for this in that extension.

So, in a link field (the “parameter” value for ->typolink) you could enter “pressrelease:123”:

Screenshot of the "link" field in the TYPO3 Backend.

Some TypoScript will usually transfer this value to the “parameter” attribute of the ->typolink call. When “pressrelease:123” enters ->typolink as the “parameter” it will be checked if “pressrelease” is a keyword with which a link handler is associated and if so, that handler is allowed to create the link.

Registering the handler for keyword “pressrelease” is done like this:

$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_content.php']
  ['typolinkLinkHandler']['pressrelease'] =
  'EXT:pressrelease/class.linkHandler.php:&tx_linkHandler';

The class file pressrelease/class.linkHandler.php contains the class tx_linkHandler which could look like this:

class tx_linkHandler {
   function main($linktxt, $conf, $linkHandlerKeyword,
      $linkHandlerValue, $link_param, &$pObj) {
      $lconf = array();
      $lconf['useCacheHash'] = 1;
      $lconf['parameter'] = 34;
      $lconf['additionalParams'] = '&tx_pressrelease[showUid]=' .
         rawurlencode($linkHandlerValue);
      return $pObj->typoLink($linktxt, $lconf);
   }
}

In this function, the value part after the keyword is set as the value of a GET parameter, &tx_pressrelease[showUid] and the “parameter” value of a new ->typolink call is set to “34” which assumes that on page ID 34 a plugin is put that will display pressrelease 123 when called with &tx_pressrelease[showUid]=123. In addition you can see the “useCacheHash” attribute for the typolink function used in order to produce a cached display.

The link that results from this operation will look like this:

<a href="index.php?id=34&amp;
  tx_pressrelease[showUid]=123%3A456&amp;cHash=c0551fead6" >

The link would be encoded with RealURL and respect config.linkVars as long as ->typolink is used to generate the final URL.
