An easy-to-use reCAPTCHA package.
use Vinkla\Recaptcha\Recaptcha;
// Create a new recaptcha instance.
$recaptcha = new Recaptcha('your-secret-key');
// Verify the recaptcha response.
$recaptcha->verify('g-recaptcha-response');
reCAPTCHA is decoupled from any library sending HTTP requests (like Guzzle), instead it uses an abstraction called HTTPlug which provides the http layer used to send requests to exchange rate services. This gives you the flexibility to choose what HTTP client and PSR-7 implementation you want to use.
Read more about the benefits of this and about what different HTTP clients you may use in the HTTPlug documentation. Below is an example using Guzzle 6:
$ composer require vinkla/recaptcha php-http/message php-http/guzzle6-adapterFirst you'll need to add the Google reCAPTCHA script to your view templates just before the closing </head> tag.
If you want to use another language you made update the
hlquery parameter value.
<script src="https://google.com/recaptcha/api.js?hl=en"></script>To display the reCAPTCHA field in your form you need to add the snippet below.
Remember to replace
your-site-keywith your actual reCAPTCHA site key.
<div class="g-recaptcha" data-sitekey="your-site-key"></div>Then create a new Vinkla\Recaptcha\Recaptcha instance.
use Vinkla\Recaptcha\Recaptcha;
$recaptcha = new Recaptcha('your-secret-key');To validate a response from the form you can use the verify() method.
use Vinkla\Recaptcha\RecaptchaException;
try {
$recaptcha->verify('g-recaptcha-response');
} catch (RecaptchaException $e) {
// If the verification fails.
