ModifyEditFormUserAccessEvent

The PSR-14 event \TYPO3\CMS\Backend\Form\Event\ModifyEditFormUserAccessEvent\ModifyEditFormUserAccessEvent 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\CMS\Backend\Form\Exception\AccessDeniedListenerException will be thrown.

Example

EXT:my_extension/Classes/Backend/EventListener/MyEventListener.php

<?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();
        }
    }
}
