Recaptcha больше не работает после обновления до версии стиля флажка

Да, «последний» recaptchalib.php не обновлялся годами. Обязательно дайте Google Doc 1-звездочный рейтинг, и они могут что-то с этим сделать. Я ходил кругами по этому, пока не понял, что recaptchalib.php файл был проблемой.

Эта почта объясняет, как использовать этот recaptchalib.php без лишних слов.

Как вы уже заявили, на вашей странице вам нужно:

<script src='https://www.google.com/recaptcha/api.js'></script>

<form method="POST" action="/your-action-page.php">

<!-- All your form fields here -->

<div class="g-recaptcha" data-sitekey="yourpublickey"></div>

<input type="submit" value="Submit" />

</form>

Тогда в your-action-page.php вам нужно следующее:

<?php

require_once('path-to/recaptchalib.php');

$secret = "yoursecretkey";

$response = null;

$reCaptcha = new ReCaptcha($secret);if ($_POST["g-recaptcha-response"]) {

$response = $reCaptcha->verifyResponse( $_SERVER["REMOTE_ADDR"],  $_POST["g-recaptcha-response"] );

}

if ($response != null && $response->success) {

// Your code to handle a successful verification

}

else {

// What happens when the CAPTCHA is entered incorrectly

}

?>

И не забудьте загрузить альтернативу recaptchalib.php:
