Laravel: Auth::user()->id trying to get a property of a non-object

Question

I\'m getting the following error \"trying to get a property of a non-object\" when I submit a form to add a user, the error is apparently on the first line: Auth::user()->id

Answer 1

you must check is user loggined ?

Auth::check() ? Auth::user()->id : null

Answer 2

id is protected, just add a public method in your /models/User.php

public function getId()
{
  return $this->id;
}

so you can call it

$id = Auth::user()->getId();

remember allways to test if user is logged...

if (Auth::check())
{
     $id = Auth::user()->getId();
}

Answer 3

Check your route for the function in which you are using Auth::user(), For getting Auth::user() data the function should be inside web middleware Route::group(['middleware' => 'web'], function () {}); .

Answer 4

If you are using Sentry check the logged in user with Sentry::getUser()->id. The error you get is that the Auth::user() returns NULL and it tries to get id from NULL hence the error trying to get a property from a non-object.

Answer 5

Your question and code sample are a little vague, and I believe the other developers are focusing on the wrong thing. I am making an application in Laravel, have used online tutorials for creating a new user and authentication, and seemed to have noticed that when you create a new user in Laravel, no Auth object is created - which you use to get the (new) logged-in user's ID in the rest of the application. This is a problem, and I believe what you may be asking. I did this kind of cludgy hack in userController::store :

$user->save();

Session::flash('message','Successfully created user!');

//KLUDGE!! rest of site depends on user id in auth object - need to force/create it here
Auth::attempt(array('email' => Input::get('email'), 'password' => Input::get('password')), true);

Redirect::to('users/' . Auth::user()->id);

Shouldn't have to create and authenticate, but I didn't know what else to do.

Answer 6

Now with laravel 4.2 it is easy to get user's id:

$userId = Auth::id();

that is all.

But to retrieve user's data other than id, you use:

$email = Auth::user()->email;
