Question

I have

Session::$default='database';
$session=Session::instance(); 

and
$session->id() displays session’s value now.
The value is stored in the sessions table as well.
Everything seems to work fine.

My question is: how to check if session exists in another action.
The $_SESSION array is undefined.

Answer 1

To access the session from any controller action or view template, simply use:

Session::instance()

For example:

$session = Session::instance();

$session->set('my_key', 'my_value');

// returns false if my_key does not exist
$my_key = $session->get('my_key', false);

To overload $_SESSION with the Kohana session, run the following inside each action method:

$_SESSION =& $session->as_array();
