typolink¶

Property

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 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
'&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 empty, the URL will be build with just the TYPO3 internal params like id,
type, M. If there are further params in URL (f.e. tx_news_pi1 for news) you should
set this value to GET to add all GET parameters.

Changed in version 10.0: With version 10.0 a breaking change was introduced. Setting
addQueryString.method to any value but GET will
trigger a E_USER_WARNING. Any POST-parameters will be ignored. Maintaining
functionality - if required at all - has to be done using domain specific
logic in according controllers or middleware implementations.

.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.

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):
parameter = t3://page?uid=51

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”:
parameter = t3://page?uid=current _blank specialLink "Very important information"

which is converted to a link like this:
<a href="?id=51" target="_blank" class="specialLink" title="Very important information">

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

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.
Link targets that are external or contain _blank will be added rel="noopener 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:
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

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:
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’ (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
    }
}
