reCAPTCHA v2 php plugin README
================

The reCAPTCHA v2 PHP Library helps you use the reCAPTCHA API. 

Documentation about reCAPTCHA v2 -> https://developers.google.com/recaptcha/intro


From reCATPCHA there are some changes like:

- RECAPTCHA_VERIFY_SERVER, now in https -> https://www.google.com/recaptcha/api/siteverify

- parameters to send by POST:
	. secret
    . remoteip
    . response


To use this plugin, you can see the example-captcha file.
You have to:


- Create your public and private api key and include your domain(s)

https://www.google.com/recaptcha/admin


- Include the recaptchalibv2.php:

require_once('recaptchalibv2.php');


- add client side integration:

echo recaptcha_get_html($publickey);


- add the server side check, for example:

if ($_POST["g-recaptcha-response"]) {
    $resp = recaptcha_check_answer ($privatekey,
                                    $_SERVER["REMOTE_ADDR"],
                                    $_POST["g-recaptcha-response"]);

    if ($resp->success) {
            echo "Everything's OK!";
    } else {
            # set the error code so that we can display it
            $error = $resp['error-codes'];
    }
}
