Laravel 8 Google reCAPTCHA Integration

Google reCAPTCHA is a popular service that helps protect websites from spam and abuse by requiring users to solve a CAPTCHA challenge. In this tutorial, we'll walk through the process of integrating Google reCAPTCHA into a Laravel 8 application to add an extra layer of security to your forms.

Step 1: Set up Google reCAPTCHA

Before you begin, make sure you have a Google reCAPTCHA API key. If you don't have one, visit the official Google reCAPTCHA website (https://www.google.com/recaptcha) to sign up and generate your keys.

Step 2: Create a new Laravel 8 project (skip this if you already have one)

If you don't have a Laravel 8 project, you can create one using Composer:

```bash

composer create-project laravel/laravel your-project-name

cd your-project-name

```

Step 3: Install the "google/recaptcha" package

Next, we need to install the "google/recaptcha" package, which provides an easy way to work with Google reCAPTCHA in Laravel.

```bash

composer require google/recaptcha

```

Step 4: Configuration

Open the `.env` file in your Laravel project and add the following lines to set your Google reCAPTCHA API keys:

```

RECAPTCHA_SITE_KEY=your_site_key

RECAPTCHA_SECRET_KEY=your_secret_key

```

Step 5: Implement reCAPTCHA in the form

Now, let's integrate reCAPTCHA into a form, such as a contact form. For demonstration purposes, let's assume you have a route, controller, and view for the contact form.

In your view file (e.g., `resources/views/contact.blade.php`), add the reCAPTCHA widget just before the form's submit button:

```html

```

Step 6: Verify reCAPTCHA response in the controller

In your controller (e.g., `app/Http/Controllers/ContactController.php`), you can validate the reCAPTCHA response before processing the form data:

```php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use Validator;

class ContactController extends Controller

{

public function submitForm(Request $request)

{

$validator = Validator::make($request->all(), [

// Your other form field validation rules go here

'g-recaptcha-response' => 'required|recaptcha',

]);

if ($validator->fails()) {

return redirect()->back()->withErrors($validator)->withInput();

}

// Process your form data here

return redirect()->back()->with('success', 'Form submitted successfully!');

}

```

Step 7: Display errors in the view

In your view, you can display any reCAPTCHA validation errors like this:
