Securing Laravel Applications Against Common Vulnerabilities

   Route::get('/posts', [PostController::class, 'index']);

Create the controller:

   @if ($userPreferences['notifications'])
       <p>Notifications are enabled.</p>
   @else
       <p>Notifications are disabled.</p>
   @endif

For data that depends on the request or user context, use middleware.

Use a service provider to load settings from the database and apply them to Laravel’s config system.

Open App\Providers\AppServiceProvider.php and update the boot method:

   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.
