How to Add Middleware in Laravel 11

7 months ago admin Laravel

In this tutorial, we will see how to add middleware in Laravel 11, now we can use bootstrap/app.php instead of http/kernel.php this change comes with the release of Laravel 11.


Create the middleware

First, let's create a new middleware I named it 'AdminMiddleware', and let's assume that we want to add an admin middleware to protect the admin routes.

                                                    
                                                                                                                
php artisan make:middleware AdminMiddleware

Register the middleware using an alias

Next inside the file bootstrap/app.php let's register the middleware and give it 'admin' as an alias.

                                                        
                                                                                                                        
<?php

use Illuminate\Foundation\Application;
use Illuminate\Foundation\Configuration\Exceptions;
use Illuminate\Foundation\Configuration\Middleware;

return Application::configure(basePath: dirname(__DIR__))
    ->withRouting(
        web: __DIR__.'/../routes/web.php',
        api: __DIR__.'/../routes/api.php',
        commands: __DIR__.'/../routes/console.php',
        health: '/up',
    )
    ->withMiddleware(function (Middleware $middleware) {
        //
        $middleware->alias([
            'admin' => \App\Http\Middleware\AdminMiddleware::class,
        ]);
    })
    ->withExceptions(function (Exceptions $exceptions) {
        //
    })->create();


Check if user is an admin

Inside the 'AdminMiddleware' let's add the code to check if the logged-in user is an admin

                                                        
                                                                                                                        
<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;

class AdminMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Closure(\Illuminate\Http\Request): (\Symfony\Component\HttpFoundation\Response)  $next
     */
    public function handle(Request $request, Closure $next): Response
    {
        if (auth()->guard('admin')->check()) {
            return $next($request);
        }
        return redirect()->back();
    }
}


Use the middleware

Now inside the web.php file, we can use the admin middleware to protect our routes.

                                                        
                                                                                                                        
Route::middleware('admin')->get('/admin', function () {
    return view('dashboard');
});
