README

Add ability to execute init method in controller before every action. Based on this answer

Example

class SampleController extends Controller implements InitControllerInterface
{
    protected $page;

    public function init(Request $request)
    {
        if ($request->get('redirect') == 1) {
            return $this->redirect('http://example.com');
        }

       $this->page = $request->get('page');
    }

    public function indexAction()
    {
        //some action code
    }
}

Instalation

1. Add library to composer.json

   "yavin/symfony-init-controller": "0.3"

   and run command

   composer update yavin/symfony-init-controller
   

2. Add service in your bundle services file Resources/config/services.xml:

   <service class="Yavin\Symfony\Controller\InitControllerSubscriber">
       <tag name="kernel.event_subscriber"/>
   </service>

   or if you have services.yml:

   services:
       symfony.controller.subscriber.init:
           class: Yavin\Symfony\Controller\InitControllerSubscriber
           tags:
               - { name: kernel.event_subscriber }

3. Then implement InitControllerInterface in controller that you want to have init method.

   namespace Acme\DemoBundle\Controller;
   
   use Symfony\Bundle\FrameworkBundle\Controller\Controller;
   use Symfony\Component\HttpFoundation\Request;
   use Yavin\Symfony\Controller\InitControllerInterface;
   
   class SampleController extends Controller implements InitControllerInterface
   {
       protected $page;
   
       public function init(Request $request)
       {
           //init method could return response, for example redirect
           if ($request->get('redirect') == 1) {
               return $this->redirect('http://example.com');
           }
   
           $this->page = $request->get('page');
       }
   
       public function indexAction()
       {
           //...
       }
   
       public function otherAction()
       {
           //...
       }
   }
