AfterBackendPageRenderEvent
New in version 12.0
The PSR-14 event After
has
been introduced which serves as a direct replacement for the removed hooks:
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
<?php
declare(strict_types=1);
namespace MyVendor\MyExtension\Backend\EventListener;
use TYPO3\CMS\Backend\Controller\Event\AfterBackendPageRenderEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;
#[AsEventListener(
identifier: 'my-extension/backend/after-backend-page-render',
)]
final readonly class MyEventListener
{
public function __invoke(AfterBackendPageRenderEvent $event): void
{
$content = $event->getContent() . ' I was here';
$event->setContent($content);
}
}
New in version 13.0
The PHP attribute \TYPO3\
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/
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.
