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()
{
return parent::implementedEvents() + [
'Crud.beforeFind' => '_beforeFind'
];
}
public function _beforeFind(\Cake\Event\Event $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()
{
return [
'Crud.beforeFind' => '_beforeFind'
];
}
public function _beforeFind(Event $event)
{
Log::debug('Inside the listener!');
}
}
