Create Middleware

We’ll remove empty spaces using Laravel middleware. Let’s create a middleware named SpaceRemover:

php artisan make:middleware SpaceRemover

Open the middleware SpaceRemover.php from app/Http/Middleware folder and paste this code:

<?php

namespace App\Http\Middleware;

use Closure;

class SpaceRemover
{
    public function handle($request, Closure $next)
    {
        $request->merge(array_map('trim', $request->all()));
        return $next($request);
    }
}

Update Kernel

Open the Kernel.php from app/Http folder and add our newly created middleware to the $middleware array.

protected $middleware = [
    //--------------
    \App\Http\Middleware\SpaceRemover::class,
];

Now our application will remove all empty spaces. You can pass empty space and test.

That’s all. Thank you.
