AfterBackendPageRenderEvent
New in version 12.0
The PSR-14 event
After has
been introduced which serves as a direct replacement for the removed hooks:
$GLOBALS['TYPO3_ CONF_ VARS'] ['SC_ OPTIONS'] ['typo3/ backend. php'] ['construct Post Process'] $GLOBALS['TYPO3_ CONF_ VARS'] ['SC_ OPTIONS'] ['typo3/ backend. php'] ['render Pre Process'] $GLOBALS['TYPO3_ CONF_ VARS'] ['SC_ OPTIONS'] ['typo3/ backend. php'] ['render Post Process']
The PSR-14 event
\TYPO3\
gets triggered after the page in the backend is rendered and includes the
rendered page body. Listeners may overwrite the page string if desired.
Example
Registration of the event listener in the extension's Services.:
services:
# Place here the default dependency injection configuration
MyVendor\MyExtension\Backend\EventListener\MyEventListener:
tags:
- name: event.listener
identifier: 'my-extension/backend/after-backend-page-render'
Read how to configure dependency injection in extensions.
The corresponding event listener class:
<?php
declare(strict_types=1);
namespace MyVendor\MyExtension\Backend\EventListener;
use TYPO3\CMS\Backend\Controller\Event\AfterBackendPageRenderEvent;
final class MyEventListener
{
public function __invoke(AfterBackendPageRenderEvent $event): void
{
$content = $event->getContent() . ' I was here';
$event->setContent($content);
}
}
