The createNewUser hook is triggered when a new front end user registers on the website. It passes the ID of the new user and the data array as arguments and does not expect a return value.
int $userId
Unique ID of the user.
array $userData
All values which have been submitted on the registration form. Be aware that
the user ID is not contained in this array ($userData['id']
is empty).
\Contao\Module $module
The front end module instance executing this hook.
// src/EventListener/CreateNewUserListener.php
namespace App\EventListener;
use Contao\CoreBundle\DependencyInjection\Attribute\AsHook;
use Contao\Module;
#[AsHook('createNewUser')]
class CreateNewUserListener
{
public function __invoke(int $userId, array $userData, Module $module): void
{
// Do something …
}
}
