too long

Question

i'm working with symfony and trying to set and get session variable to pass trough a twig template.

I tryied the way is in the symfony example: http://symfony.com/doc/current/components/http_foundation/sessions.html

$session = new Session();
$session->start();

// set and get session attributes
$session->set('name', 'Drak');
$session->get('name');

Twig:

{{ app.session.get('balance') }}

Returns this error message:

An exception has been thrown during the rendering of a template ("Failed to start the session: already started by PHP ($_SESSION is set).")

I check my php.ini and the sessions doesn't start automatycally, also there is no other session live.

I tried this way too:

   $session = $this->getRequest()->getSession();
// We store an attribute
        $session->set('FrenchTouch', 'Julian');
// in another controller for another request, we retrieve the value of this attribute
        $value = $session->get('FrenchTouch');
        print_r(array($value));

But returns this other error:

FatalErrorException: Error: Call to a member function get() on a non-object

Answer 1

I did find the answer,

The problem wasn't in the way to get/set the session, the issue comes because i'm passing the info trough controllers and i was using a non-native symfony way. The correct way to pass info in controllers is:

$response = $this->forward('YourBundle:YourController:YourAction', array(
 'user'=>$user
));
return $response;

And then in the other controller set the sessions and render the template.
