View Helper

In your AppView, load the Helper as

$this->loadHelper('Authentication.Identity');

For very simple checking whether the user is logged in you can use

if ($this->Identity->isLoggedIn()) {
    ...
}

Getting user data is as easy as

$username = $this->Identity->get('username');

The following check can be used to tell if a record that belongs to some user is the current logged in user and compare other fields as well:

$isCurrentUser = $this->Identity->is($user->id);
$isCurrentRole = $this->Identity->is($user->role_id, 'role_id');

This method is mostly a convenience method for simple cases and not intended to replace any kind of proper authorization implementation.
