Laravel - Controllers

Laravel - Controllers 

Open the command prompt

Execute the following command to create UserController

C:\xampp\htdocs\laraveldev>php artisan make:controller UserController 

After successful execution, you will receive the following output.
Controller created successfully.

You can see the created controller at app/Http/Controller/UserController.php with some basic coding already written for you and you can add your own coding based on your need.

Controller Middleware

Middleware can also be assigned to controller’s route or within your controller’s constructor. You can use the middleware method to assign middleware to the controller. The registered middleware can also be restricted to certain method of the controller.

Assigning Middleware to Route

Route::get('profile', [
   'middleware' => 'auth',
   'uses' => 'UserController@showProfile'
]);

Here we are assigning auth middleware to UserController in profile route.

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;

class UserController extends Controller {
   public function __construct(){
      $this->middleware('auth');
   }
}

Here we are assigning auth middleware using the middleware method in the UserController’s constructor.

Example
Step 1 − Add the following lines to the app/Http/routes.php file and save it.

<?php
Route::get('/usercontroller/path',[
   'middleware' => 'First',
   'uses' => 'UserController@showPath'
]);

Step 2 − Create a middleware called FirstMiddleware by executing the following line.

php artisan make:middleware FirstMiddleware

Add the following code in the handle method of the newly created FirstMiddleware at app/Http/Middleware.

<?php
namespace App\Http\Middleware;
use Closure;

class FirstMiddleware {
   public function handle($request, Closure $next) {
      echo '
First Middleware';
      return $next($request);
   }
}

Step 4 − Create a middleware called SecondMiddleware by executing the following line.

php artisan make:middleware SecondMiddleware

Step 5 − Add the following code in the handle method of the newly created SecondMiddleware at app/Http/Middleware.

<?php
namespace App\Http\Middleware;
use Closure;

class SecondMiddleware {
   public function handle($request, Closure $next){
      echo '
Second Middleware';
      return $next($request);
   }
}

Step 6 − Create a controller called UserController by executing the following line.

php artisan make:controller UserController

Step 7 − After successful execution of the URL, you will receive the following output −
Controller created succesfully

Step 8 − Copy the following code to app/Http/UserController.php file.

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;

class UserController extends Controller {
   public function __construct(){
      $this->middleware('Second');
   }
   public function showPath(Request $request){
      $uri = $request->path();
      echo '
URI: '.$uri;
      
      $url = $request->url();
      echo '
';
      
      echo 'URL: '.$url;
      $method = $request->method();
      echo '
';
      
      echo 'Method: '.$method;
   }
}

Step 9 − Now launch the php’s internal web server by executing the following command, if you haven’t executed it yet.

php artisan serve

Step 10 − Visit the following URL. http://localhost:8000/usercontroller/path
