Laravel Auth user id in controller

You need to use the Auth facade in the controller;

add this line just before class definition.

use Auth;

Try this,

auth()->user()->id;

When you try to get the user by using $user = Auth::user(); Laravel tries to load Auth class from the current location. In your case, it is

'App\Http\Controllers\Frontend'

So Laravel is looking for Auth class inside the Frontend directory, which is not in. That's why you got that error message saying not found as below,

'Class 'App\Http\Controllers\Frontend\Auth' not found'

If you use use Auth; method, you have to type use Auth; in each and every controller that you are going to use the Auth controller.

Instead of typing use Auth; in each and every controller you can simply use the Laravel helper function as auth()->user().

from that you can get any value from the db like:

auth()->user()->id

auth()->user()->f_name
