php - 联系表单脚本未运行，白页

Question

尝试提交包含以下条目的联系表单时出现白屏:- 姓名- 电子邮件- 主题- 消息

我正在尝试通过我的网站接收电子邮件。我检查了所有变量名称等，似乎一切都是正确的。我是 PHP 的新手，所以我对接下来要尝试的事情有点不清楚。谢谢

<form method"POST" action="action/form-submit.php"> <!--NO FOR ATTRIBUTE, NOT ADDING FUNCTIONALITY-->
                <h2>Contact Me:</h2>
                  <label>Your Name:</label>
                    <input name="name" type="text" placeholder="Your Name..." required/>
                  <label>Email:</label>
                    <input name="email" type="email" placeholder="Email..." required/>
                  <label>Query Type:</label>
                    <select id="qry" name="query" required>
                      <option value="" disabled selected>Please Select:</option>
                      <option value="jobs">Jobs</option>
                      <option value="website">Website Issues</option>
                      <option value="info">Information</option>
                    </select>
                  <label>Your Message:</label>
                  <textarea name="info" placeholder="Your Message..." required></textarea>
                  <input type="submit" value="Submit">
              </form>

然后是PHP代码:

<?php
  $vname = $_POST['name'];
  $vemail = $_POST['email'];
  $vquery = $_POST['query'];
  $vmessage = $_POST['info'];

  $email_from = "test@gmail.com";

  $email_subject = "New Website Submission";

  $email_body = "Visitor Name: $vname.\n".
                  "Visitor Email: $vemail.\n".
                    "Visitor Subject: $vquery.\n".
                      "Visitor Message: $vmessage.\n";

  $to = "bradleyarcher98@gmail.com";

  $headers = "From: $email_from \r\n";

  $headers .= "Reply-To: $vemail \r\n";

  mail($to,$email_subject,$email_body,$headers);

  header("location: contact.html");

?>

为了查看错误，您需要打开 PHP 错误处理。

启用此功能后，您将不再只是看到一个白页，而是会向浏览器发送一条包含文件名、行号和描述错误的消息的错误消息。
