Middleware in Laravel 11

Introduction to Middleware in Laravel

Hello friends! Today we want to talk about Middleware in Laravel 11. When we discuss Middleware, we are actually talking about a layer that can manage the request to the controller before or after executing a specific action.

In other words, Middleware is very useful for managing requests. For example, we can use Middleware to check if a user is logged in or not, or whether the user has permission to access a specific page. This increases the security of our application significantly.

Also, Middleware can be used for other purposes like logging, or even timestamping requests. In Laravel, by default, we have several Middleware such as auth, guest, and verified that manage user statuses.

So let’s take a look at how to create a new Middleware in Laravel and how to utilize it effectively. This task is quite simple and we can accomplish this with just a few lines of code.

Creating a New Middleware

To create a new Middleware, start with the command line and run the following command:

php artisan make:middleware CheckAge

This command will create a new file named CheckAge.php in the app/Http/Middleware directory. Now let’s take a look at this file.

Middleware Code

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\Auth;

class CheckAge
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @param  int  $age
     * @return mixed
     */
    public function handle($request, Closure $next, $age)
    {
        if (Auth::check() && Auth::user()->age < $age) {
            return redirect('home');
        }

        return $next($request);
    }
}
