ModifyEditFormUserAccessEvent
New in version 12.0
This event serves as a more powerful and flexible alternative for the removed
$GLOBALS
hook.
The PSR-14 event
\TYPO3\
provides the full database row of the record in question next to the
exception, which might have been set by the Core. Additionally, the event allows
to modify the user access decision in an object-oriented way, using
convenience methods.
In case any listener to the new event denies user access, while it was initially
allowed by Core, the \TYPO3\
will be thrown.
Example
<?php
declare(strict_types=1);
namespace MyVendor\MyExtension\Backend\EventListener;
use TYPO3\CMS\Backend\Form\Event\ModifyEditFormUserAccessEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;
#[AsEventListener(
identifier: 'my-extension/backend/modify-edit-form-user-access',
)]
final readonly class MyEventListener
{
public function __invoke(ModifyEditFormUserAccessEvent $event): void
{
// Deny access for creating records of a custom table
if ($event->getTableName() === 'tx_myext_domain_model_mytable' && $event->getCommand() === 'new') {
$event->denyUserAccess();
}
}
}
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.
