Cakephp - get user id in controller when using Auth

Question

It seems like a two-step process to get this,

    $u = $this->Auth->user();
    $uid = $u['User']['id'];

Isn't there a variable set somewhere once a user is logged in? (Sorry for the dumb question.)

Answer 1

In CakePHP there are several ways to get the user id from the session, here are a few examples

To get the session user id within the controller use:

$uid = $this->Auth->User('user_id');

To get the session user id within a view, use: ( Not Recommended, I would set this in the controller)

$uid = $this->Session->read('Auth.User.id');

To get the session user id within a model, use: (Not Recommended, but a solution)

$uid = CakeSession::read('Auth.User.id');

I don't recommend the above to get the session user id from within the model, I would pass it via the controller, use:

$this->Model->function($uid);

You can also get the session user id via pure php, use: (Althought using Cake you should stick with the conventions)

$uid = $_SESSION['Auth']['User']['id'];

And there are more approaches, this is just a few...

I think you can do $uid = $this->Auth->user('id'); - check the api: http://api.cakephp.org/class/auth-component#method-AuthComponentuser
