Laravel，从刀片模板文件调用控制器方法

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!

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()
