Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

What is Group Middleware?

Group Middleware allows developers to apply common filtering logic to a specific set of routes, without having to manually apply the Middleware to each individual route.

This can be particularly useful in situations where you have a set of routes that require a specific type of filtering or processing, such as authentication or role-based access control.

By the help of php artisan command, we create Middleware in laravel.

$ php artisan make:middleware <MiddlewareName>

Middlewares will be stored inside /app/Http/Middleware. To register middleware inside application, Kernel.php file will be used which is inside /app/Http. Kernel.php, it’s a class file which contains registration of middlewares.

Example – Group Middleware Implementation

Let’s take an example to understand the concept of group middleware inside laravel application.

  • Create a Middleware which checks country, when we open URL.
  • Example We will have 3 routes in which two routes should be protected by middleware and third one is open to access for everyone.
  • US, IN, AFG should be allowed inside application, they can access application routes.
  • UK, AUS should be restricted to use or access route.

Create a Middleware

Open project into terminal and run this artisan command.

$ php artisan make:middleware CountryCheck

It will create a file with name CountryCheck.php inside /app/Http/Middleware folder.

Open CountryCheck.php file and write this following code into it.

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;

class CountryCheck
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle(Request $request, Closure $next)
    {
        if ($request->country && !in_array($request->country, array("us", "in", "afg"))) {
            return redirect("noaccess");
        }
        return $next($request);
    }
}

If request $request->country is NOT in list of these (US, IN, AFG) then it will open no access page.

Register Middleware in Application

Open Kernel.php from /app/Http. Search for $middlewareGroups and add this.

protected $middlewareGroups = [
    //...

    'apprestrict' => [ 
       \App\Http\Middleware\CountryCheck::class,
    ],
    
    //...
];

apprestrict is the name of group middleware.

Create NoAccess & Protected Routes

Open web.php from /routes and add these route into it.

//...

Route::view("noaccess", "noaccess");

Route::get("route-1", function(){ echo "<h3>Welcome To Route 1</h3>"; });

// Protected group by middleware
Route::group(["middleware" => ["apprestrict"]], function(){

   Route::get("route-2", function(){ echo "<h3>Welcome To Route 2</h3>"; });
  
   Route::get("route-3", function(){ echo "<h3>Welcome To Route 3</h3>"; });
});

//...

Next, we need to create noaccess.blade.php file.

Create NoAccess Page

Create a file called noaccess.blade.php inside /resources/views folder. Open file and write this simple code into it.

Normal Routes

URL – http://127.0.0.1:8000/route-1/?country=us

*** Welcome To Route 1 ***

URL – http://127.0.0.1:8000/route-1/?country=uk

*** Welcome To Route 1 ***

Protected Routes

URL – http://127.0.0.1:8000/route-2/?country=us

*** Welcome To Route 2 ***

URL – http://127.0.0.1:8000/route-2/?country=uk
