Use Auth in AppServiceProvider - laravel

Question

I need the ID of the user who is logged in to get a photo in the profile table, here I am trying to use View but only in the index function that gets $profile, I want all files in the view to have $profile
public function index(){
$profil = Profil_user::where('user_id',$auth)->first();
View::share('profil', $profil);
return view('user.index');
}
I have also tried AppServiceProvider but I get an error in the form of a null value if I don't log in, is there a solution to my problem?
public function boot(){
$auth = Auth::user();
dd($auth);
}

exist several way to pass a variable to all views. I explain some ways.
1. use middleware for all routes that you need to pass variable to those:
create middleware (I named it RootMiddleware)
php artisan make:middleware RootMiddleware
go to app/Http/Middleware/RootMiddleware.php and do following example code:
public function handle($request, Closure $next) {
if(auth()->check()) {
$authUser = auth()->user();
$profil = Profil_user::where('user_id',$authUser->id)->first();
view()->share([
'profil', $profil
]);
}
return $next($request);
}
then must register this middleware in app/Http/Kernel.php and put this line 'root' => RootMiddleware::class, to protected $routeMiddleware array.
then use this middleware of routes or routes group, for example:
Route::group(['middleware' => 'root'], function (){
// your routes that need to $profil, of course it can be used for all routers(because in handle function in RootMiddleware you set if
});
or set for single root:
Route::get('/profile', 'ProfileController#profile')->name('profile')->middleware('RootMiddleware');
2. other way that you pass variable to all views with view composer
go to app/Http and create Composers folder and inside it create ProfileComposer.php, inside ProfileComposer.php like this:
<?php
namespace App\Http\View\Composers;
use Illuminate\View\View;
class ProfileComposer
{
public function __construct()
{
}
public function compose(View $view)
{
$profil = Profil_user::where('user_id', auth()->id)->first();
$view->with([
'profil' => $profil
]);
}
}
now it's time create your service provider class, I named it ComposerServiceProvider
write this command in terminal : php artisan make:provider ComposerServiceProvider
after get Provider created successfully. message go to config/app.php and register your provider with put this \App\Providers\ComposerServiceProvider::class to providers array.
now go to app/Providers/ComposerServiceProvider.php and do like following:
namespace App\Providers;
use App\Http\View\Composers\ProfileComposer;
use Illuminate\Support\Facades\View;
use Illuminate\Support\ServiceProvider;
class ComposerServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* #return void
*/
public function boot()
{
View::composer(
'*' , ProfileComposer::class // is better in your case use write your views that want to send $profil variable to those
);
/* for certain some view */
//View::composer(
// ['profile', 'dashboard'] , ProfileComposer::class
//);
/* for single view */
//View::composer(
// 'app.user.profile' , ProfileComposer::class
//);
}
/**
* Register the application services.
*
* #return void
*/
public function register()
{
}
}
3. is possible that without create a service provider share your variable in AppServiceProvider, go to app/Provider/AppServiceProvider.php and do as follows:
// Using class based composers...
View::composer(
'profile', 'App\Http\View\Composers\ProfileComposer'
);
// Using Closure based composers...
View::composer('dashboard', function ($view) {
//
});
I hope be useful

Answer 2

you can use this
view()->composer('*', function($view)
{
if (Auth::check()) {
$view->with('currentUser', Auth::user());
}else {
$view->with('currentUser', null);
}
});
