联系人提交按钮重定向到空白。PHP url？

Question

我有一个联系表格，我想将其发送到我域中的电子邮件地址。然而，在点击 "Submit" 按钮后，网站被重定向到 .PHP url ，它给我：

HTTP ERROR 500: This page isn’t working "mywebsite.com" is currently unable to handle this request.

没有收到电子邮件并且 header("Location: ") 没有重定向。我目前正在使用 Bluehost。您可以在 acromojo.com/contact 找到我正在处理的表格。我还没有添加安全性，只是想让表单先工作。

我做错了什么？

HTML:

<form method="post" action="contactform.php">

    <div><select name="projectType">
      <option value="0">Start A Project</option>
      <option value="1">General Inquiry</option>
      <option value="2">Collaborating</option>
    </select></div></br>
    <input name="name" type="text" placeholder="Full Name" required>
    <input name="company" type="text" placeholder="Company / Organization"></br>
    <input name="phone" type="phone" placeholder="Phone Number" required>
    <input name="email" type="email" placeholder="Email Address"></br>
    <input name="location" type="text" placeholder="Location">
    <select name="find">
      <option value="0">How did you hear about us?</option>
      <option value="1">Social Media</option>
      <option value="2">Search Engine</option>
      <option value="3">Referrals / Recommendations</option>
      <option value="4">Other</option>
    </select></br></br>
    <textarea name="message" placeholder="Please tell us a little about your project, timeline, and budget" row="4" required></textarea></br>
    <label>Sign me up for the latest news, events, and more
      <input name="newsletter" type="checkbox" checked="checked">
      <span class="checkmark"></span>
    </label>
        <input type="submit" name="submit" value="SUBMIT">

</form>

PHP:

<?php

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

    $name = $_POST['name'];
    $subject = $_POST['projectType'];
    $phone = $_POST['phone'];
    $email = $_POST['email'];
    $location = $_POST['location'];
    $find = $_POST['find'];
    $message = $_POST['message'];
    $newsletter = $_POST['newsletter'];

    $headers = "From: $email";
    $txt = "You have received an e-mail from ".$name."\n\n"
      "Location: ".$location."\n"
      "Contact: ".$phone.", ".$email."\n"
      "Found from: ".$find."\n\n"
      .$message;

    mail("hello@acromojo.com", $subject, $txt, $headers);
    header("Location: contact.html?mailsent");
  }

aaaaaa123456789评论后我得到了答案。我检查了它返回的 error_log：

PHP Parse error: syntax error, unexpected '"Location: "' (T_CONSTANT_ENCAPSED_STRING)

修复：“\r\n”"Location: "

收件人： "\r\n 地点："
