=========================================================
|
|
Feature: #95083 - New PSR-14 ModifyClearCacheActionsEvent
|
|
=========================================================
|
|
|
|
See :issue:`95083`
|
|
|
|
Description
|
|
===========
|
|
|
|
A new PSR-14 event :php:`\TYPO3\CMS\Backend\Backend\Event\ModifyClearCacheActionsEvent`
|
|
has been added to TYPO3 Core. This event is fired in the
|
|
:php:`\TYPO3\CMS\Backend\Backend\ToolbarItems\ClearCacheToolbarItem`
|
|
class and allows extensions 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", the convenience
|
|
method :php:`add` for the :php:`cacheActions` and
|
|
:php:`cacheActionIdentifiers` arrays.
|
|
|
|
Registration of the Event in your extensions' :file:`Services.yaml`:
|
|
|
|
.. code-block:: yaml
|
|
|
|
MyVendor\MyPackage\Toolbar\MyEventListener:
|
|
tags:
|
|
- name: event.listener
|
|
identifier: 'my-package/toolbar/my-event-listener'
|
|
|
|
The corresponding event listener class:
|
|
|
|
.. code-block:: php
|
|
|
|
use TYPO3\CMS\Backend\Backend\Event\ModifyClearCacheActionsEvent;
|
|
|
|
class MyEventListener {
|
|
|
|
public function __invoke(ModifyClearCacheActionsEvent $event): void
|
|
{
|
|
// do magic here
|
|
}
|
|
|
|
}
|
|
|
|
Impact
|
|
======
|
|
|
|
This event can be used to modify the clear cache actions, shown in the
|
|
TYPO3 Backend top toolbar.
