Custom¶

Any class can be used as a Crud Listener, even the controller.

Using a controller as a listener¶

We override the implementedEvents() method in the controller, and bind the Crud.beforeFind event to the _beforeFind() method in the controller.

<?php
namespace App\Controller;

class BlogsController extends AppController {

  public function implementedEvents(): array
  {
      return parent::implementedEvents() + [
          'Crud.beforeFind' => '_beforeFind'
      ];
  }

  public function _beforeFind(\Cake\Event\EventInterface $event, \Cake\ORM\Query $query)
  {

  }

}

Creating a listener class¶

Creating your own listener class is very similar to using a controller as a listener.

<?php
namespace App\Lib\Listeners;

use Cake\Event\Event;
use Crud\Listener\BaseListener;

class MyListener extends BaseListener
{
    public function implementedEvents(): array
    {
        return [
            'Crud.beforeFind' => '_beforeFind'
        ];
    }

    public function _beforeFind(Event $event)
    {
        Log::debug('Inside the listener!');
    }
}
