Phalcon Session

Question

I have set my session, however it is not being seen on the other pages.

within the loginController, the login function has:

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

I want when the person log in, it redirects to the index page, but a check needs to be done. However when I tried the below code, it throws an error that session was not defined.

  if ($session->has("auth")) { 
  //Retrieve its value 
  $name = $session->get("auth"); 
  echo("   ".$name); 
  exit;
  } 

I would like when the session is set from the login controller, that the session variable is seen and can be checked is a session was infact set or not. If it is set, show the page. If it was not set, redirect to login.
