ModifyClearCacheActionsEvent

New in version 11.4

The PSR-14 event \TYPO3\CMS\Backend\Backend\Event\ModifyClearCacheActionsEvent is fired in the \TYPO3\CMS\Backend\Backend\ToolbarItems\ClearCacheToolbarItem class and allows extension authors to modify the clear cache actions, shown in the TYPO3 backend top toolbar.

The event can be used to change or remove existing clear cache actions, as well as to add new actions. Therefore, the event also contains, next to the usual "getter" and "setter" methods, the convenience method add() for the cacheActions and cacheActionIdentifiers arrays.

Example

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

declare(strict_types=1);

namespace MyVendor\MyExtension\Backend\EventListener;

use TYPO3\CMS\Backend\Backend\Event\ModifyClearCacheActionsEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;

#[AsEventListener(
    identifier: 'my-extension/toolbar/my-event-listener',
)]
final readonly class MyEventListener
{
    public function __invoke(ModifyClearCacheActionsEvent $event): void
    {
        // do magic here
    }
}
