I am setting variables in AppController in order to use them in
default.ctp.

This is my code:

        function beforeRender ( )
        {
                @Controller::loadModel('User');
                $login_url = [trimmed];
                $this->set('loginurl', $login_url);
                $this->set('user', $this->Cookie->read('User'));
                $this->set('examdata', $this->User->query('select listing from 
exams
limit 0,1'));
                $this->set('exam', $this->Cookie->read('exam'));
        }

The logic for above code has been performed in beforeFilter().

Now when I use the variables in default.ctp, such as say $loginurl, or
$examdata, I get:

Undefined variable: loginurl

or Undefined variable: examdata


What am I doing wrong?
