Using custom middleware but using the auth

Create a new middleware ChecksAdminPrivileges and add it to a middleware group with the Auth middleware running first

In the middleware you simply write the logic you want, and voilá now it checks with every request if you are an admin, do this otherwise do that

inside the ChecksAdminPrivileges it could go something like this:

$user = $request->user();
    if($user->is_admin != 1)
    {
    // logic to go to non admin places
            return redirect('/');
    }
    return $next($request);

That will take care of your controller Admin logic, but view specific you can simply in your layout file load an admin partial only if the user is an admin

ie. You need to show some links in the navigation to your admin that you don't want other users to see

So separate your navigation blade files. Maybe nav.blade.php and admin-nav.blade.php

In your layout file only include the admin-nav if the has the is-admin attribute

First of all, I want to preface this with the fact that I think you really should look into the built in authorisation gate system that Laravel provides (see here)

If you really want to go this specific route then you're going to want to:

1. Create the middleware (I've named it AuthorizeAdministrator but this is completely up to you)

<?php

namespace App\Http\Middleware;

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

class AuthorizeAdministrator
{
    /**
     * Handle an incoming request.
     *
     * @param \Illuminate\Http\Request $request
     * @param \Closure                 $next
     *
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if (! Auth::user()->is_admin) {
            throw new AuthorizationException;
        }

        return $next($request);
    }
}

1. Register this middleware in App\Http\Kernel::$routeMiddleware:

protected $routeMiddleware = [
    // ...

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

    // ...
];

1. Utilise it as a middleware parameter on your routes:

$router->group(['middleware' => 'admin'], function (Registrar $router) {
    // ...
});

Thanks both for your comments, will try that or further more go with gates.

if u want know more then have a look https://laracasts.com/series/laravel-5-from-scratch/episodes/14

@theUnforgiven I have a similar middleware. I check an attribute on the User model, and then send the appropriate HTTP response if the user’s not an administrator:

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Auth\Access\AuthorizationException;

class VerifyUserIsAdministrator
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     * @throws \Illuminate\Auth\Access\AuthorizationException
     */
    public function handle($request, Closure $next)
    {
        if ($request->user()->isAdministrator()) {
            return $next($request);
        }

        throw new AuthorizationException;
    }
}
