Laravel 5.4 - Simple and easy solution to create admin middleware to authenticate user type

Posted 5 years ago By Ajay Gupta 67304

In this tutorial, I will let you know the easy solution to create middleware to make sure if logged user has the privileges for admin.

I have user table having column name "user_type" that manage the status of the users.

Please follow the steps to handle admin middleware :

Add Middleware

First i will create AdminMiddleware.php in following path app/Http/Middleware/AdminMiddleware.php

<?php
namespace App\Http\Middleware;
use Closure;
class AdminMiddleware
{
    /**
     * Handle an incoming request. User must be logged in to do admin check
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if (\Auth::user()->user_type == 'Admin')
        {
            return $next($request);
        }
        return redirect()->guest('/');
    }
}

<?php

namespace App\Http\Middleware;

use Closure;

class AdminMiddleware
{

    /**
     * Handle an incoming request. User must be logged in to do admin check
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if (\Auth::user()->user_type == 'Admin')
        {
            return $next($request);
        }

        return redirect()->guest('/');
    }
}

After creating middleware don't forget to register the middleware as routeMiddleware in app/Http/Kernel.php

app/Http/Kernel.php

protected $routeMiddleware = [
        'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
        'can' => \Illuminate\Auth\Middleware\Authorize::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
        'admin' => \App\Http\Middleware\AdminMiddleware::class,
    ];

protected $routeMiddleware = [
        'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
        'can' => \Illuminate\Auth\Middleware\Authorize::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
        'admin' => \App\Http\Middleware\AdminMiddleware::class,
    ];

Now you have successfully configured the admin middleware.

Ok, let's assign this admin middleware in routes/web.php

Routes

In this step, we will add some routes within the admin middleware to check it is working fine or not.

Route::group(array('prefix'=>'administration','middleware' => ['auth', 'admin']), function ()
  {
     Route::get('dashboard',function(){
         return "Welcome to Administration";
     });
  });

Route::group(array('prefix'=>'administration','middleware' => ['auth', 'admin']), function ()
  {
     Route::get('dashboard',function(){
     	return "Welcome to Administration";
     });
  });
