javascript - 联系表单 mailer.php 返回空白页面

Question

联系表单工作正常，直到我尝试添加 reCAPTCHA。我已经设法使 reCAPTCHA 出现，有 recaptchalib 和 mailer.php (显示空白页面的页面)。有什么想法我做错了吗？

这是mailer.php

<?php 
if(isset($_POST['submit'])) {

    // check reCAPTCHA information
    require_once('recaptchalib.php');

    $privatekey = "privatekey";
    $resp = recaptcha_check_answer ($privatekey,
                                $_SERVER["REMOTE_ADDR"],
                                $_POST["recaptcha_challenge_field"],
                                $_POST["recaptcha_response_field"]);

    // if CAPTCHA is correctly entered!                        
    if ($resp->is_valid) {
        // great success!    
        $myemail = "operations@socialmarketing.com";

        /* Check all form inputs using check_input function */
        $name = $_POST['inputName'];
        $email = $_POST['inputEmail'];
        $subject = $_POST['inputSubject'];
        $message = $_POST['inputMessage'];

        /* Let's prepare the message for the e-mail */

        $subject = "Message From LGBT campaign Contact Form";

        $message = "

        China LGBT Contact Form

        Name: $name
        Email: $email

        Message:
        $message

        ";

        /* Send the message using mail() function */
        mail($myemail, $subject, $message);

        /* Redirect visitor to the thank you page */
        header('Location: successPage.html#contact');

    } else {
       // alert the captcha is not correct

    }
}?>

这是我的 HTML 页面，我已将其制作为 .php 页面

<div class="marketing">
<div class="intro" id="contact">
  <h1>Contact Us</h1>
  <p>If you would like to stay informed about our progress or would like to help with the campaign, please fill out this form to send us an email.</p>

        <div class="col-lg-10">
          <textarea class="form-control" rows="4" name="inputMessage" placeholder="Your message..."></textarea>
        </div>
      </div>

      <div class="form-group">
        <div class="col-lg-10 col-lg-offset-2">
        <p>Prove you are not a spambot</p>
        <?php require_once('recaptchalib.php');
            $publickey = "publickey";
            echo recaptcha_get_html($publickey);
          ?>

    </div>
  </div>

      <div class="form-group">
        <div class="col-lg-offset-2 col-lg-10">
          <button type="submit" class="btn btn-primary">Send Message</button>
        </div>
      </div>
    </form>
  </div>
</div>

任何对此的帮助将不胜感激。

非常感谢

将按钮更改为:

<input type="submit" class="btn btn-primary" value="Send Message" name="submit">

POST 正在寻找名为 submit 的命名属性。

它基于您的条件语句，因此内部不会执行任何内容:

if(isset($_POST['submit'])) {...}

您也没有 named 表单元素来配合 $subject = $_POST['inputSubject'];

添加一个:

Subject:<input type="text" class="form-control" name="inputSubject" placeholder="Subject">

或者简单地测试:

$subject = "Form submitted";

您应该确保所有字段均已填写。如果主题留空或其他任何内容，您可能会因此而收不到邮件，尤其是电子邮件字段。

另一个原因可能是因为您没有正确的 header ，包括 From:

通过邮件访问 PHP.net 网站:

• http://php.net/manual/en/function.mail.php

示例 From: 网站 header :

$headers = 'From: webmaster@example.com' . "\r\n" .
    'Reply-To: webmaster@example.com' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

并修改mail($myemail, $subject, $message);
到 mail($myemail, $subject, $message, $headers);

引用它们:

Note:

When sending mail, the mail must contain a From header. This can be set with the additional_headers parameter, or a default can be set in php.ini.

Failing to do this will result in an error message similar to Warning: mail(): "sendmail_from" not set in php.ini or custom "From:" header missing. The From header sets also Return-Path under Windows.

添加error reporting到文件顶部，这将有助于查找错误。

<?php 
error_reporting(E_ALL);
ini_set('display_errors', 1);

// rest of your code

旁注:错误报告只能在暂存阶段完成，而不能在生产阶段完成。
