Laravel 10 Validate Internet Protocol (IPv6) Tutorial

Last Updated on by in Laravel

In this comprehensive guide, you will learn how to validate Internet Protocol (IPv6) addresses in Laravel.

Properly validating IP addresses, especially IPv6, is essential for ensuring your application accepts only correct and secure data. Laravel’s built-in validation features make this task straightforward.

For Laravel developers, ensuring the validity of IPv6 addresses is crucial for applications that rely on networking functions, such as those that track user activity, manage server connections, or utilize geo-location data. By properly validating IPv6 addresses, you can prevent data corruption and security issues.

In this tutorial, we will cover:

  • Setting up your form: Begin by creating an HTML form in your Laravel application that includes an input field for the IPv6 address.
  • Creating the controller: Define a controller method to handle form submissions and validation.
  • Applying the IPv6 validation rule: Use Laravel’s built-in ipv6 rule to validate the submitted IPv6 address.
  • Handling successful submissions: Once validation passes, proceed with the desired actions such as processing the data or sending a success response.
  • Handling validation errors: Provide feedback to users when the submitted IPv6 address does not pass the validation rule.

By the end of this guide, you will have a solid understanding of how to validate IPv6 addresses in Laravel, ensuring that your applications handle IP data correctly and securely. Let’s get started!

How to Validate IPv6 (Internet Protocol Version 6) in Laravel 10

  • Step 1: Install Laravel App
  • Step 2: Generate Controller
  • Step 3: Set Up Controller
  • Step 4: Define Routes
  • Step 5: Build Form with Bootstrap
  • Step 6: Test IPv6 Validation

Install Laravel App

In order to install the fresh Laravel application, make sure to configure Composer tool on your development machine.

Open the terminal, on the command-prompt hit the given command and execute the command to download the app.

composer create-project --prefer-dist laravel/laravel laravel-boom

Once the app is generated, move inside the app directory.

cd laravel-boom

Generate Controller

A controller handles the core logic of Laravel apps, and it’s just a simple file where all the feature-related code resides.

You may create it manually or simply invoke the suggested below command from the command prompt.

php artisan make:controller ProductController

Now the ProductController file has been created, you now have to follow the subsequent step.

Set Up Controller

Get into the app\Http\Controllers\ directory and look for ProductController.php file. In this file you have to place the suggested code.

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Blade;
class ProductController extends Controller
{
    public function ipv6form()
    {
        return view('index');
    }
    public function validateForm(Request $request)
    {
        $request->validate([
            'ip_address' => 'required|ipv6',
        ]);
        dd('Form submitted successfully!');
    }
}

The ProductController class, will have the two functions and handle the view for the form and required validation for the IPv6 input field.

Define Routes

To build the routes for handling the form and validation, get inside the routes/ folder and add the given code into the web.php file.

<?php
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\ProductController;
/*
|--------------------------------------------------------------------------
| API Routes
|--------------------------------------------------------------------------
|
*/
Route::get('/my-form', [ProductController::class, 'ipv6form']);
Route::post('/submit-form', [ProductController::class, 'validateForm'])->name(
    'validate.ip'
);

Build Form with Bootstrap

Now, you need to go to resources/views/ folder, inside this folder you have create index.blade.php file and insert the suggested code into the view file.

<!DOCTYPE html>
<html>
<head>
    <title>Laravel IPv6 Validation</title>
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
    <div class="container mt-5">
        @if (count($errors) > 0)
            <div class="alert alert-danger">
                @foreach ($errors->all() as $error)
                    {{ $error }} <br>
                @endforeach
            </div>
        @endif
        <form action="{{ route('validate.ip') }}" method="post">
            @csrf
            <div class="mb-3">
                <label>IP Address</label>
                <input type="text" class="form-control" name="ip_address">
            </div>
            <div>
                <button class="btn btn-danger">Send</button>
            </div>
        </form>
    </div>
</body>
</html>

Add the bootstrap CSS link within the head section to allow building the form using bootstrap form UI component.

Define the form tag, pass the route that makes the post request and evoke the server side validation for IPv6 form field.

Test IPv6 Validation

In this segment, we have to just run the laravel development server. Hence, execute the given command to run the app.

php artisan serve

You can test or view the app through given url:

http://127.0.0.1:8000/my-form
