How to get User()->id in Controllers (Laravel 8+) - laravel

Question

I am trying to select tasks by user('id'), but I can't get it in a Controller, where I selecting data from DB.
I have tried many thing and some of them from stackoverflow, but it isn't working.
I tried:
1. $userId = Auth::check() ? Auth::id() : true;
2. Auth::user()->id;
3. public function getUserId(){
on Model} - and then get this value on Controllers
and some other things
I have the simplest code:
I installed registration: npm artisan ui --auth something like that
I installed vuejs (on Laravel)
I created api on Laravel, and some logic on vue
I didn't touch "app.blade.php" it's the same as it was.
I can get data, user: name, id and all what I want in file "app.blade.php" but I need those data in folder->file: App\Http\Controllers{{SomeController}}, but I don't know how.
Was someone in this situation?
How can I get user id in Controllers?
Thanks guys for earlier.

Answer 1

If you need user id, just use one of this :
auth()->id();
using Auth facade's
\Auth::id();
or, using Request instance
$request->user()->id
Follow this simple controller code, i showed 3 different way here :
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
class SomeController extends Controller
{
public function __construct()
{
$this->middleware('auth');
}
public function getUserId(Request $request)
{
$user = Auth::user(); // Retrieve the currently authenticated user...
$id = Auth::id(); // Retrieve the currently authenticated user's ID...
$user = $request->user(); // returns an instance of the authenticated user...
$id = $request->user()->id; // Retrieve the currently authenticated user's ID...
$user = auth()->user(); // Retrieve the currently authenticated user...
$id = auth()->id(); // Retrieve the currently authenticated user's ID...
}
}

Answer 2

Auth::user()->id;
This should work if you have Auth middleware on that controller method where you try to get it, please check do you added that middleware.
For checking you can use php arisan route:list command.

Answer 3

Is someone still searching an answer on this question. I have some explanation how can you do this.
Laravel has a Router which routes authorization process through that Controller which you want, so you should redirect that process on your Router and in Controller create constructor which allows you to take user id.
How can you do that?:
1. First of all you should find Controller and Route which responsible for authorization and registration users.
In my case it was:
a)App\Http\Controllers\HomeController
b)routes\web.php
2. Second, you should redirect your authorization Router to the Controller where you trying to get Auth::id();
In my case it was:
App\Http\Controllers\TasksController
so, in routes\web.php I did this:
//was
Route::get('/', [App\Http\Controllers\HomeController::class, 'index'])->name('home');
//was
Auth::routes();
//was
Route::get('/home', [App\Http\Controllers\HomeController::class, 'index'])->name('home');
//added
Auth::routes();
//added
Route::get('/home', [App\Http\Controllers\TasksController::class, 'index'])->name('home');
perhaps you should have index function on that controller
3. Third you should add constructor in your controller where you want to get user id, this constructor I took from HomeController, it already was there.
In my case it was:
public function __construct()
{
$this->middleware('auth');
}
code with function on my TasksController:
public function __construct()
{
$this->middleware('auth');
}
public function index()
{
$userId = Auth::check() ? Auth::id() : true;
}
And now I can take user id.
PS: constructor I added on the top in class TasksController in Controller
