我在网站上有一个salesforce web-to-lead表单。一切正常，但没有recaptcha或任何方式来防止垃圾邮件。所以我下载了recaptcha，得到了所有设置，我还按照here的说明获取$ _POST数据，验证recaptcha是否正确，然后将其提交给salesforce。
我得到了所有这些设置但是当我提交表单时，它只是转到我的check-this-first.php（我称之为contactFormConfirm.php）页面并且只是空白。它没有触及retURL或实际提交给salesforce。
任何可以帮助我摆脱的光都会很棒。提前谢谢。

我知道这是一个旧线程，但我在尝试做同样的事情时遇到了它并提出了这个解决方案：
<?php
ob_start();
session_start();
require_once('recaptchalib.php');
$key_public = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
$key_private = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
$captchaFailed = false;
$response = null;
$reCaptcha = new ReCaptcha($key_private);
if (!function_exists('curl_version')) {
die('Curl package missing.');
}
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
if (isset($_POST['g-recaptcha-response'])) {
$response = $reCaptcha->verifyResponse(
$_SERVER['REMOTE_ADDR'],
$_POST['g-recaptcha-response']
);
if ($response !== null) {
if ($response->success) {
$fields = $_POST;
$sendURL = $fields['sendURL'];
unset($fields['sendURL']);
unset($fields['g-recaptcha-response']);
$fields_string = http_build_query($fields);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $sendURL);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);
$result = curl_exec($ch);
curl_close($ch);
} else {
$captchaFailed = true;
}
} else {
$captchaFailed = true;
}
} else {
$captchaFailed = true;
}
}
if ($captchaFailed && count(get_included_files()) < 3) {
echo 'reCAPTCHA failed! Please go back and try again.';
}
?>
您需要创建一个名为sendURL的隐藏输入字段，其中包含您要将表单发送到的网址的值。
您可以将表单的操作设置为包含上述代码的文件，也可以将其包含在包含表单的页面顶部，并将操作留空。
将所有内容都包含在同一页面中的示例可能是这样的：
<?php require_once('form-submit.php'); ?>
<html>
<body>
<form method="post">
<input type="hidden" name="sendURL" value="https://login.salesforce.com/servlet/servlet.WebToLead?encoding=UTF-8&...">
<label for="name">Name:</label>
<input type="text" name="name" value="<?php if (!empty($_POST['name'])) { echo $_POST['name']; } ?>">
<label for="email">E-Mail:</label>
<input type="text" name="email" value="<?php if (!empty($_POST['email'])) { echo $_POST['email']; } ?>">
<label for="message">Message:</label>
<textarea name="message"><?php if (!empty($_POST['message'])) { echo $_POST['message']; } ?></textarea>
<?php if ($captchaFailed): ?>
<p>reCAPTCHA failed! Please try again!</p>
<?php endif; ?>
<div class="g-recaptcha" data-sitekey="<?php echo $key_public; ?>"></div>
</form>
<script src="https://www.google.com/recaptcha/api.js"></script>
</body>
</html>
你可以在任何需要验证reCAPTCHA的情况下使用它，然后再将表单数据发送到其他地方。
