Laravel Controllers Development Tutorials, Guides & Insights

• Pass shared data to controllers using dependency injection when possible.

Sharing data between views and controllers in Laravel is a fundamental part of building scalable applications. By following these best practices and using tools like View::share, middleware, and service providers, you can ensure consistency, improve performance, and simplify your codebase.

   namespace App\Http\Controllers;

   class FileController extends BaseController
   {
       public function upload()
       {
           if (!$this->canUploadFiles()) {
               return redirect()->back()->with('error', 'File uploads are disabled.');
           }

           // Handle file upload logic here
       }
   }

• Centralized Logic: Common functionality is defined in one place, reducing code duplication.
• Ease of Maintenance: Updates to shared logic automatically apply to all child controllers.
• Improved Readability: Child controllers remain focused on specific actions, while shared concerns are handled in the Base Controller.

You can access the shared data singleton using the app() helper or dependency injection.

In any controller, retrieve the shared data:
