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¶

Registration of the event listener in the extension's Services.yaml:

EXT:my_extension/Configuration/Services.yaml

services:
  # Place here the default dependency injection configuration

  MyVendor\MyExtension\Backend\EventListener\MyEventListener:
    tags:
      - name: event.listener
        identifier: 'my-extension/backend/allowed-items'

Read how to configure dependency injection in extensions.

The corresponding event listener class:

EXT:my_extension/Classes/Backend/EventListener/MyEventListener.php

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Backend\EventListener;

use TYPO3\CMS\Backend\Controller\Event\ModifyAllowedItemsEvent;

final class MyEventListener
{
    public function __invoke(ModifyAllowedItemsEvent $event): void
    {
        $event->addAllowedItem('someItem');
        $event->removeAllowedItem('anotherItem');
    }
}
