Use sessions to save and read data for a user between pages.

Within Controllers:

// store a user id in the session
$this->Session->write('User.id', $userId);

// read a user id from the session

Within Views:

// read a user id from the session
$userId = $session->read('User.id');

You can use any key you want if you prefer something over "User.id". I simply use this since it is what the AuthComponent defaults to if you are using that.
