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

In Laravel 5.6 I use

use Auth;
$user_id = Auth::user()->id;

as the other suggestion

Auth::id()

seems to apply to older versions of Laravel 5.x and didn't work for me.
