how to create admin middleware in laravel

Open terminal and run a command:

cd projectPath
php artisan make:middleware admin

go to app/Http from project folder and open kernel.php file.
inside kernel file you should add your admin middleware as route middleware:

protected $routeMiddleware = [

        'auth' => \App\Http\Middleware\Authenticate::class,

        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,

        'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,

        'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,

        'can' => \Illuminate\Auth\Middleware\Authorize::class,

        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,

        'signed' => \Illuminate\Routing\Middleware\ValidateSignature::class,

        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,

        'verified' => \Illuminate\Auth\Middleware\EnsureEmailIsVerified::class,

        'admin' => \App\Http\Middleware\admin::class,

    ];

make sure your user table have a field/column named "role" in your database:

Now you can modify handle function to check which role is loggedin inside  newly created admin.php middleware file app/Http/middleware

public function handle($request, Closure $next)

    {

        return $next($request);

    }
