使用启动引导“代理”主题的提交表单时出错

我通常在Rails工作，我是第一次尝试PHP。我使用的是启动引导模板（代理），但似乎无法正确提交"与我联系"表单。我在 PHP 文件中为提交定义了收件人电子邮件。当我在本地运行它，填写表单并单击提交时，我从contact_me.js文件中收到失败消息。

这个StackOverflow问题类似，没有得到答案。任何关于我做错了什么的建议将不胜感激。谢谢！

contact_me.php

<?php
// Check for empty fields
if (empty($_POST['name']) ||
    empty($_POST['email']) ||
    empty($_POST['phone']) ||
    empty($_POST['message']) ||
    !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)
) {
    echo "No arguments Provided!";
    return false;
}
$name = $_POST['name'];
$email_address = $_POST['email'];
$phone = $_POST['phone'];
$message = $_POST['message'];
// Create the email and send the message
$to = 'RemovedEmailForStackOverflow@gmail.com'; // Add your email address inbetween the '' replacing yourname@yourdomain.com - This is where the form will send a message to.
$email_subject = "A guest has messaged yourname:  $name";
$email_body = "You've received a message from your website contact form.'n'n" . "Here are the details:'n'nName: $name'n'nEmail: $email_address'n'nPhone: $phone'n'nMessage:'n$message";
$headers = "From: noreply@gmail.com'n"; // This is the email address the generated message will be from. We recommend using something like noreply@yourdomain.com.
$headers .= "Reply-To: $email_address";
mail($to, $email_subject, $email_body, $headers);
return true;
?>
