How to add Ajax capabilites to Symfony

Question

I have a set of sessions in a page, which I want to remove using AJAX. i.e click on a link, and without having to navigate for a new page, just remove the session, and show

Answer 1

Example controller:

use Symfony\Component\HttpFoundation\JsonResponse;


public function ajaxRemoveSessionAction()
{
    // Destroy the desired session
    $session = $this->getRequest()->getSession();
    $session->remove('name');

    return new JsonResponse(array('success' => true));
}

Example routing:

ajax_remove_session:
    pattern:  /remove-session
    defaults: { _controller: FooTestBundle:Page:ajaxRemoveSession }

Example twig:

Remove session

These are just examples need testing.
