How to set the global variable on Laravel Controller? - laravel

Question

Everyone.
Every function on a controller, I am using the same variables.
public function store(Request $request)
{
$user = auth()->user();
$user_name = $user->name;
$user_id = $user->id;
$init_pdf = url('/') . '/images/' . 'upload/' . $user_name . '/' . $name;
...
}
public function signedPdf(request $request)
{
$user = auth()->user();
$user_name = $user->name;
$user_id = $user->id;
$name = $user_name . $user_id . '.' . $file->extension();
...
}
I want to set the global variable for the common variables.
How can I set it?
thanks

Answer 1

Normally you can directly set things in the constructor but there is an issue with Controllers in regards to middleware. The Controller is resolved before the request has passed through the middleware stack. Which means you usually won't have things like sessions or auth available yet. You would want to use a closure based middleware in the constructor of the Controller to be able to set this value:
protected $user;
public function __construct()
{
$this->middleware(function ($request, $next) {
$this->user = $request->user();
// also can set other variables here as well
// let the request continue through the stack
return $next($request);
});
}
Then you should have access to $this->user in your methods.
Another answer: Assign user values for whole controller in laravel
Duplicate of that basically.

This solution is worked for me
In
app/Http/Controllers/Controller.php
Import Illuminate\Support\Facades\Auth
namespace App\Http\Controllers;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Support\Facades\Auth; <--- like this
class Controller extends BaseController
{
use AuthorizesRequests, DispatchesJobs, ValidatesRequests;
protected $userId;
protected $userName;
public function __construct()
{
$this->userId = Auth::user()->id;
$this->userName = Auth::user()->name; <--- "Admin"
}
}
Now $this->userId and $this->userName is available wherever extends Controller
For example:
app/Http/Controllers/API/v1/ConfigController.php
class ConfigController extends Controller
{
public function index() {
return $this->userName; <--- "Admin"
}
