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?

You can use $uid = $this->Auth->user('id');

Check the api documentation: https://api.cakephp.org/1.3/class-AuthComponent.html#_user

For everybody using the newer Cakephp v4.x: https://api.cakephp.org/4.4/class-Cake.Controller.Component.AuthComponent.html#user()

The fact that you can supply a key arg is right there in the API... I think I'll take a look in there more often. – Owen Jul 01 '10 at 16:08
I get `Notice: Notice (1024): Undefined property: MyController::$Auth` – geoidesic Aug 04 '22 at 07:54

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...

This was a great answer and this should be the marked as the Accepted Answer — justinhartman, Oct 11 '13 at 16:05
+1 for recommendation on passing from controller to model, instead of calling `CakeSession::read('Auth.User.id');` in model. — Fr0zenFyr, Sep 11 '15 at 10:40

You can also get the user details from the session if the Auth class is not available to you.

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

This is helpful if you don't have the AuthComponent registered at the AppController level – Rob Allen Nov 27 '12 at 19:23

CakePhp 2.x:

Anywhere:

AuthComponent::user('id')

Inside a controller:

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

Even this question being posted way before present version, I'm gonna answer how to do it in Cakephp v4.x, because I just needed it and got a hard time finding this info, and it may be useful to someone else.

$identity = $this->request->getAttribute('authentication')->getIdentity();

Now, you have an IdentityInterface ORM-like object, which returns values from pairs named after the DB table you're using to track users. So, you can get all info from your DB, like:

$identity['email']
$identity['full_name']
$identity['id']
// etc

$this->Session is deprecated, as Simon says above, but now $this->request->session(); is also deprecated. For now, as August 2021 and CakePhp 4 the correct answer is:

$this->request->getSession()->read('User.id');

This may be of no use, but I was having a error cause by $this->Auth->user(); This problem was solved using this instead. I am not sure of the route of the issue, but it came up when calling a function from a Model in the same action as I used $this->Auth->user(); Using AuthComponent::user('id') solved the issues.

$this->Session is deprecated

Use something like this

$session = $this->request->session();
$user_id = $session->read('Auth.User.id');
