php - Salesforce Web-to-リードを使用した再キャプチャ

Question

Web サイトに Salesforce Web-to-Lead フォームがあります。すべて正常に動作しますが、recaptcha やスパムを防止する方法はありません。そこで、recaptcha をダウンロードし、すべての設定を行いました。また、こちらの手順に従って$_POST データを取得し、recaptcha が正しいことを確認してから、セールスフォースに送信しました。

私はその設定をすべて取得しましたが、フォームを送信すると、check-this-first.php (contactFormConfirm.php と呼びました) ページに移動し、空白になります。retURL にヒットしたり、実際にセールスフォースに送信したりしません。

私を助けるために流すことができるどんな光も素晴らしいでしょう. 前もって感謝します。

私が使用しているコードは次のとおりです。

これが古いスレッドであることは知っていますが、同じことをしようとしているときに遭遇し、この解決策を思いつきました:

<?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.';
}
?>

sendURLフォームを送信したい URL の値で呼び出される非表示の入力フィールドを作成する必要があります。

フォームのアクションを上記のコードを含むファイルに設定するか、フォームのページの上部に含めてアクションを空白のままにすることができます。

すべてを同じページに含める例は、次のようになります。

<?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>

これは、フォームデータを別の場所に送信する前に reCAPTCHA を検証する必要があるほとんどすべての場合に使用できます。
