ModifyAllowedItemsEvent¶
New in version 12.0: This event has been introduced together with
ModifyLinkHandlersEvent to
serve as a direct replacement for the following removed hook
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['LinkBrowser']['hooks']
.
It replaces the method modifyAllowedItems()
in this hook.
The PSR-14 event
\TYPO3\CMS\Backend\Controller\Event\ModifyAllowedItemsEvent
allows extension authors to add or remove from the list of allowed link
types.
Example¶
<?php
declare(strict_types=1);
namespace MyVendor\MyExtension\Backend\EventListener;
use TYPO3\CMS\Backend\Controller\Event\ModifyAllowedItemsEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;
#[AsEventListener(
identifier: 'my-extension/backend/allowed-items'
)]
final class MyEventListener
{
public function __invoke(ModifyAllowedItemsEvent $event): void
{
$event->addAllowedItem('someItem');
$event->removeAllowedItem('anotherItem');
}
}
New in version 13.0: The PHP attribute \TYPO3\CMS\Core\Attribute\AsEventListener
has been
introduced to tag a PHP class as an event listener. Alternatively, or if you
need to be compatible with older TYPO3 versions, you can also register an
event listener via the Configuration/Services.yaml
file. Switch to
an older version of this page for an example or have a look at the section
Implementing an event listener in your extension.
