PageContentPreviewRenderingEvent
New in version 12.0
This event has been introduced which serves as a drop-in replacement for the removed
$GLOBALS
hook.
Use the PSR-14 event
\TYPO3\
to ship an alternative rendering for a specific content type or
to manipulate the record data of a content element.
Example
Registration of the event listener in the extension's Services.:
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/preview-rendering-example-ctype'
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\View\Event\PageContentPreviewRenderingEvent;
final class MyEventListener
{
public function __invoke(PageContentPreviewRenderingEvent $event): void
{
if ($event->getTable() !== 'tt_content') {
return;
}
if ($event->getRecord()['CType'] === 'example_ctype') {
$event->setPreviewContent('<div>...</div>');
}
}
}
