Symfony2, check if an action is called by ajax or not

Question

I need, for each action in my controller, check if these actions are called by an ajax request or not.

If yes, nothing append, if no, i need to redirect to the home page.

I have just find if($this->getRequest()->isXmlHttpRequest()), but i need to add this verification on each action..

Do you know a better way ?

Answer 1

It's very easy!

Just add $request variable to your method as use. (For each controller)

<?php namespace YOUR\Bundle\Namespace  use Symfony\Component\HttpFoundation\Request;  class SliderController extends Controller {      public function someAction(Request $request)     {         if($request->isXmlHttpRequest()) {             // Do something...         } else {             return $this->redirect($this->generateUrl('your_route'));         }     }  } 

If you want to do that automatically, you have to define a kernel request listener.

Answer 2

For a reusable technique, I use the following from the base template

{# app/Resources/views/layout.html.twig #} {% extends app.request.xmlHttpRequest       ? '::ajax-layout.html.twig'      : '::full-layout.html.twig' %} 

So all your templates extending layout.html.twig can automatically be stripped of all your standard markup when originated from Ajax.
