Add your keys

If you do not have keys already then visit https://www.google.com/recaptcha/admin to generate them. Edit this file and set the respective keys in $siteKey and $secret. Reload the page after this.

`POST` data

setExpectedHostname($_SERVER['SERVER_NAME']) ->verify($_POST['g-recaptcha-response'], $_SERVER['REMOTE_ADDR']); if ($resp->isSuccess()): // If the response is a success, that's it! ?>

Success!

That's it. Everything is working. Go integrate this into your real project.
