How to integrate google reCAPTCHA v3 in laravel

Integrating Google reCAPTCHA v3 in Laravel is a straightforward process that involves a few steps.

Let's follow these steps:

Step 1 - Create a Google reCAPTCHA v3 account and generate site and secret keys from the reCAPTCHA dashboard.

Step 2 - Install the Google reCAPTCHA package for Laravel by this command in your project directory:

composer require google/recaptcha "^1.0"

Step 3 -  Add your site and secret keys to the `.env` file of your Laravel project:

RECAPTCHA_SITE_KEY=your_site_key_here
RECAPTCHA_SECRET_KEY=your_secret_key_here

Step 4 -  Create a form where you want to add the reCAPTCHA validation.

Add the following code inside the form for reCaptcha:

<input type="hidden" name="recaptcha_response" id="recaptchaResponse">

Step 5 -  Add the following script tag to the head section:

<script src="https://www.google.com/recaptcha/api.js?render=your_site_key_here"></script>

Step 6 -  Add the following JavaScript code to the form page or layout file:

<script>
    grecaptcha.ready(function() {
        grecaptcha.execute('your_site_key_here', {action: 'submit'}).then(function(token) {
            document.getElementById('recaptchaResponse').value = token;
        });
    });
</script>

Step 7 -  In your Laravel controller, validate the reCAPTCHA response using the `Validator` facade:

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;

public function submitForm(Request $request)
{
    $validator = Validator::make($request->all(), [
        'recaptcha_response' => 'required|recaptcha',
    ]);

    if ($validator->fails()) {
        // Handle validation errors
    }

    // Process form data
}

Note: the `recaptcha` rule is added to the validation rules array.

Step 8 -  Finally, run your Laravel project and test the form to make sure that the reCAPTCHA validation is working.

That's it! You have successfully integrated Google reCAPTCHA v3 in your Laravel project.
