How to access the session variable in the controller

Question

I have created a session variable in one controller and I want to access it in another controller. In loginsuccess controller I set the session:

$session->set('id',$id);

How can I access this variable in another controller?

Answer 1

There is session service which you should use:

$id = $this->get('session')->get('id');

or

$this->get('session')->set('id', $id);

Answer 2

On a more general note, if your controller extends from the base Symfony controller (Symfony\Bundle\FrameworkBundle\Controller\Controller) you can get the session in 3 ways:

1. $session = $this->container->get('session');
2. $session = $this->get('session'); (which basically is a shortcut to 1)
3. $session = $request->getSession();
