Pass variable from controller to layout in CakePHP

My variable loggedIn is defined in my AppController in the beforeFilter() function, as follows:

function beforeFilter(){
        $this->Auth->loginRedirect = array('controller'=> 'questions', 'action' => 'home');
        $this->Auth->logoutRedirect = array('controller'=> 'questions', 'action' => 'home');
        $this->Auth->allow('signup', 'confirm', 'home', 'show');
        $this->Auth->authorize = 'controller';
        $this->Auth->userScope = array('User.confirmed' => '1');
        $this->set('loggedIn', $this->Auth->user('id'));
    }

In my layout, I am testing the value of the loggedIn variable using the following: 

<?php if($loggedIn): ?>

When I run the application I get this error: 

Undefined variable: loggedIn [APP\View\Layouts\default.ctp

Can you help me? Thank you in advance.

There is a better way to do this.

In your AppController:

public function beforeFilter() {
    parent::beforeFilter();
    $this->set('loggedIn', $this->Auth->loggedIn());
}

Or, if you need to access the loggedIn var in your controllers and your views:

public function beforeFilter() {
    parent::beforeFilter();
    $loggedIn = $this->Auth->loggedIn();
    $this->set('loggedIn', $loggedIn);
}

Why is this in beforeFilter()? So that the variable is accessible before preparing the page. This returns a Boolean, perfect for deciding if a user is logged in or not, so evaluate it as:

<?php if($logged_in===true): ?>

If you do still need the user ID or other user attributes, then use this in your view:

$id = $this->Auth->user('id');

As on the bottom of this page

You wouldn't set individual attributes in beforeFilter if they can already be accessed in your view - you want to keep controllers as skinny as possible.

function beforeFilter(){
        parent::beforeFilter(); 
        $this->Auth->loginRedirect = array('controller'=> 'questions', 'action' => 'home');
        $this->Auth->logoutRedirect = array('controller'=> 'questions', 'action' => 'home');
        $this->Auth->allow('signup', 'confirm', 'home', 'show');
        $this->Auth->authorize = 'controller';
        $this->Auth->userScope = array('User.confirmed' => '1');
        $this->set('loggedIn', $this->Auth->user('id'));
    }

Change you beforeFilter function add line parent::beforeFilter();, after that in layout file you can use <?php if($loggedIn): ?>
