How do I create and access Symfony 2 session variables in my controllers. I used like this.
$session = new Session();
$session->start();
$session->set('loginUserId',$user['user_id']);
I want to know how to use the above session variable in all my controllers to access.
Session variables on the client are read-only. They cannot be modified.
One way of using Sessions in Symfony in controller is:
setting:
$this->get('session')->set('loginUserId', $user['user_id']);
getting:
$this->get('session')->get('loginUserId');
If you use standard framework edition
From the docs:
Symfony sessions are designed to replace several native PHP functions. Applications should avoid using session_start(), session_regenerate_id(), session_id(), session_name(), and session_destroy() and instead use the APIs in the following section.
and:
While it is recommended to explicitly start a session, a sessions will actually start on demand, that is, if any session request is made to read/write session data.
So sessions is started automatically and can be accessed e.g. from controllers via:
public function indexAction(Request $request)
{
$session = $request->getSession();
...
}
or:
public function indexAction()
{
$session = $this->getRequest()->getSession();
// or
$session = $this->get('session');
...
}
than:
// store an attribute for reuse during a later user request
$session->set('foo', 'bar');
// get the attribute set by another controller in another request
$foobar = $session->get('foobar');
// use a default value if the attribute doesn't exist
$filters = $session->get('filters', array());
