Laravel 8 middleware example; In this tutorial, you will learn how to create and how to use middleware in laravel 8 app.
Laravel middleware filters all the HTTP requests in laravel based projects. For example when the user is doing any request that time middleware check user is logged in or not and redirect accordingly. Any user is not logged in but he wants to access to the dashboard or other things in projects that time middleware filter request redirects to the user.
Now, we will give an example of active or inactive users accesses laravel 8 app or not. So, add this middleware with routes to restrict logged users to access routes, if he/she is inactive by admin.
How to use middleware in Laravel 8
- Step 1 – Create Middleware
- Step 2 – Register Middleware
- Step 3 – Implement Logic Into Your Middleware File
- Step 4 – Add Route
- Step 5 – Add Method in Controller
Step 1 – Create Middleware
In this step, open terminal and execute the following command to create custom middleware in laravel 8 app. So let’s open your command prompt and execute below command on it:
php artisan make:middleware CheckStatus
Step 2 – Register Middleware
Register middleware, so go to app/http/kernel.php and register your custom middleware here:
app/Http/Kernel.php
<?php
namespace App\Http;
use Illuminate\Foundation\Http\Kernel as HttpKernel;
class Kernel extends HttpKernel
{
....
/**
* The application's route middleware.
*
* These middleware may be assigned to groups or used individually.
*
* @var array
*/
protected $routeMiddleware = [
....
'checkStatus' => \App\Http\Middleware\CheckStatus::class,
];
}
Step 3 – Implement Logic Into Your Middleware File
After successfully register your middleware in laravel project, go to app/http/middleware and implement your logic here :
app/Http/Middleware/CheckStatus.php
<?php
namespace App\Http\Middleware;
use Closure;
class CheckStatus
{
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
if (auth()->user()->status == 'active') {
return $next($request);
}
return response()->json('Your account is inactive');
}
}
Step 4 – Add Route
In this step, simply create a route and use custom middleware with routes for filter every http request:
//routes/web.php
use App\Http\Controllers\HomeController;
use App\Http\Middleware\CheckStatus;
Route::middleware([CheckStatus::class])->group(function(){
Route::get('home', [HomeController::class,'home']);
});
Step 5 – Add Method in Controller
In this step, create one method name home and add this method on HomeController.php file, which is placed on app/Http/Controllers/ directory:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class HomeController extends Controller
{
public function home()
{
dd('You are active');
}
}
?>
