LinkBrowser API


Each tab rendered in the link browser has an associated link handler, responsible for rendering the tab and for creating and editing of links belonging to this tab.

Here is an example for a custom link handler in the link browser:

A custom link browser to link to GitHub issues

In most use cases, you can use one of the link handlers provided by the Core. For an example, see Tutorial: Custom record link browser.

If no link handler is available to deal with your link type, you can create a custom link handler. See Tutorial: Create a custom link browser.

Tab registration

LinkBrowser tabs are registered in page TSconfig like this:

TCEMAIN.linkHandler.<tabIdentifier> {
    handler = TYPO3\CMS\Recordlist\LinkHandler\FileLinkHandler
    label = LLL:EXT:recordlist/Resources/Private/Language/locallang_browse_links.xlf:file
    displayAfter = page
    scanAfter = page
    configuration {
        customConfig = passed to the handler

The options displayBefore and displayAfter define the order how the various tabs are displayed in the LinkBrowser.

The options scanBefore and scanAfter define the order in which handlers are queried when determining the responsible tab for an existing link. Most likely your links will start with a specific prefix to identify them. Therefore you should register your tab at least before the 'url' handler, so your handler can advertise itself as responsible for the given link. The 'url' handler should be treated as last resort as it will work with any link.


You may have the need to modify the list of available LinkHandlers based on some dynamic value. For this purpose you can register hooks.

The registration of a LinkBrowser hook generally happens in your ext_tables.php and looks like:

$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['LinkBrowser']['hooks'][1444048118] = [
    'handler' => \Vendor\Ext\MyClass::class,
    'before' => [], // optional
    'after' => [] // optional

The before and after elements allow to control the execution order of all registered hooks.

Currently the following list of hooks is implemented:

modifyLinkHandlers(linkHandlers, currentLinkParts)
May modify the list of available LinkHandlers and has to return the final list.
modifyAllowedItems(allowedTabs, currentLinkParts)
May modify the list of available tabs and has to return the final list.
