How to Set Middleware in Laravel

1. Create Middleware

You can create a middleware using the Artisan command. This will generate a middleware file in the app/Http/Middleware directory.

php artisan make:middleware CheckAge
                        

This command creates a file named CheckAge.php in the app/Http/Middleware directory.

2. Define Middleware Logic

Open the CheckAge.php file and define the logic in the handle method. For example, to restrict access to users under 18:

public function handle($request, Closure $next)
{
    if ($request->age < 18) {
        return redirect('home');
    }

    return $next($request);
}
                        

3. Register Middleware

You need to register your middleware in the app/Http/Kernel.php file. Add it to the $routeMiddleware array to use it with specific routes:

protected $routeMiddleware = [
    'check.age' => \App\Http\Middleware\CheckAge::class,
];
                        

4. Apply Middleware to Routes

You can apply middleware to routes or groups in the routes/web.php file. For example:

Route::get('/profile', function () {
    // Profile logic here
})->middleware('check.age');
                        

Now, the middleware will check the user’s age before granting access to the profile page.
