CONTROLLER MIDDLEWARE

  • Middleware in Laravel is a powerful mechanism for filtering HTTP requests entering your application. Middleware acts as a bridge or filter between the incoming request and your application’s routes or controllers. It can perform various tasks like authentication, authorization, logging, modifying the request or response, and more.

Creating Middleware

  • php artisan make:middleware MiddlewareName

Controller Middleware

  • Middleware may be assigned to the controller’s routes in your route files:

In Kernel.php of http directory

Route::get(‘profile’, [UserController::class, ‘show’])->middleware(‘newMiddleware’);

  • Or, you may find it convenient to specify middleware within your controller’s constructor.
  • Using the middleware method within your controller’s constructor, you can assign middleware to the controller’s actions:

class UserController extends Controller

{

public function construct()

{

$this->middleware(‘auth’);

$this->middleware(‘log’)->only(‘index’);

$this->middleware(‘subscribed’)->except(‘store’);

}

}

Simple Grouping of Route based on prefix

Route::prefix(‘admin’)->group(function () {

// Routes defined here will have the ‘admin’ prefix.

Route::get(‘dashboard’, [HomeController::class, ‘dashboard’]);

Route::get(‘users’, [HomeController::class, ‘users’]); Route::get(‘settings’, [HomeController::class,

‘settings’]);

});

Applying Miidleware to a group

Route::prefix(‘admin’)->middleware(‘newMiddleware’)-

>group(function () {

// Routes defined here will have the ‘admin’ prefix and use the ‘newMiddleware’ middleware.

Route::get(‘dashboard’,

[HomeController::class,’dashboard’]); Route::get(‘users’,

[HomeController::class,’users’]);

Route::get(‘settings’,

[HomeController::class,’settings’]);

});

Restful Controller

  • In Laravel, a RESTful resource controller is a controller that provides a set of predefined methods for handling common CRUD (Create, Read, Update, Delete) operations on a resource. Resources are typically associated with database tables or Eloquent models, and RESTful resource controllers help you create routes and controller methods for managing these resources efficiently.

Laravel makes everything easy!!

  • Command for making Restful Resource Controller
  • php artisan make:controller PostController –resource

Defining Route for controller:

  • In your routes/web.php file, you can define resourceful routes using the Route::resource() method. Here’s an example:
  • Route::resource(‘posts’, PostController::class);
  • This single line of code generates multiple routes for common CRUD operations, including:
  • GET /posts (index method): Display a list of all posts.
  • GET /posts/create (create method): Show the form for creating a new post.
  • POST /posts (store method): Store a newly created post in the database.
  • GET /posts/{id} (show method): Display the details of a specific post.
  • GET /posts/{id}/edit (edit method): Show the form for editing a post.
  • PUT/PATCH /posts/{id} (update method): Update a specific post in the database.
  • DELETE /posts/{id} (destroy method): Delete a specific post from the database.
