Laravel, calling controller method from blade template file - php

Question

Heey guys! I use Laravel 5.4, WAMP for localhost. I am struggling with the problem to call a Controller#methodName within my header.blade.php file, because I want to show in my header.blade.php file all notifications for the User. Normally I was getting all needed data with the help of routes in different pages. But for this case I need to call without using routes. Here is my code for my NotificationController:
class NotificationController extends Controller
{
public function getNotification(){
$notifications = Notification::where('user_id',Auth::user()->id)->get();
$unread=0;
foreach($notifications as $notify){
if($notify->seen==0)$unread++;
}
return ['notifications'=>$notifications, 'unread'=>$unread];
}
}
And I should receive all these data in my header file. I have used: {{App::make("NotificationController")->getNotification()}}
and {{NotificationController::getNotification() }} But it says Class NotificationController does not exist. Please heelp!

Answer 1

Instead of calling the controller method to get notifications, you can make a relationship method in your User model to retrieve all the notifications that belongs to the user and can use Auth::user()->notifications. For example:
// In User Model
public function notifications()
{
// Import Notification Model at the top, i.e:
// use App\Notification;
return $this->hasMany(Notification::class)
}
In your view you can now use something like this:
#foreach(auth()->user()->notifications as $notification)
// ...
#endforeach
Regarding your current problem, you need to use fully qualified namespace to make the controller instance, for example:
app(App\Http\Controllers\NotificationController::class)->getNotification()

Answer 2

Try using the full namespace:
For instance, App\Http\Controllers\NotificationController::getNotification
but of course, controllers aren't meant to be called the way you're using them. They're meant for routes. The better solution is to add a relationship in your user model like so:
public function notifications()
{
return $this->hasMany(Notification::class)
}
And then use this in your view like so:
#foreach(Auth::user()->notifications as $notification)
