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¶
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/modify-edit-form-user-access'
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\Form\Event\ModifyEditFormUserAccessEvent;
final 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();
}
}
}
