Question

我试图让reCaptcha在同一个索引中工作。我试过这个：

<html>
  <body>
    <form action="index.php" method="post">
      <?php
        require_once('recaptchalib.php');
        $privatekey = "YOUR_PRIVATE_KEY_HERE";
        if (isset($_POST['submit'])) {
          $resp = recaptcha_check_answer ($privatekey,
            $_SERVER["REMOTE_ADDR"],
            $_POST["recaptcha_challenge_field"],
            $_POST["recaptcha_response_field"]);

          if (!$resp->is_valid) {
            echo "<script language='javascript'>
              window.alert('Sorry cannot send email as you have failed to provide correct captcha! Try again...')
            </script>";
          } else {
            echo "<script language='javascript'>
              window.alert('Thank you for submitting the track. We will be in touch with you very soon. Click Ok to redirect you to the Homepage.')
            window.location.href='http://www.xmasterofficial.tk/'
           </script>";
          }
       }
       $publickey = "YOUR_PUBLIC_KEY_HERE";
       echo recaptcha_get_html($publickey);
      ?>
     <br/>
     <input type="submit" value="submit" />
    </form>
  </body>
</html>

问题

即使答案正确或错误，window.alert和window.location.href也无效。

当你点击提交按钮时，它应该弹出一个window.alert如果答案是好的并重定向到主页或弹出一个window.alert来重试，如果答案是错误的。

编辑：您可以运行它。你需要google中的recaptchalib.php（链接：https://code.google.com/p/recaptcha/downloads/list?q=label:phplib-Latest）

P.S。这是一个带有工作验证码的完整表格。您可以根据需要使用它。不要忘记用自己的密钥替换$privatekey和$publickey。您可以从此处获取密钥：Google reCaptcha
