php - 代码审查 - 在电子邮件脚本上不断出现 500 错误

Question

我使用 PHP/AJAX 从表单中通过电子邮件发送一些信息。下面的基本表单，AJAX 和 PHP 脚本，不断收到 500 错误，我不知道为什么！我经常使用相同的设置或非常相似的设置，我已经在服务器上测试了“邮件”功能，并且工作正常。

任何帮助都是极好的！

谢谢

// quickquote form send
$(function() {

// Get the form.
var form = $('#quickquote');

// Get the messages div.
var formMessages = $('#form-messages');

// Set up an event listener for the contact form.
$(form).submit(function(e) {
    // Stop the browser from submitting the form.
    e.preventDefault();

    // Serialize the form data.
    var formData = $(form).serialize();

    // Submit the form using AJAX.
    $.ajax({
        type: 'POST',
        url: $(form).attr('action'),
        data: formData
    })
    .done(function(response) {
        // Make sure that the formMessages div has the 'success' class.
        $(formMessages).removeClass('alert alert-danger');
        $(formMessages).addClass('alert alert-success');

        // Set the message text.
        $(formMessages).text(response);

        // Clear the form.
  $('#quickquote')[0].reset();
     })
    .fail(function(data) {
        // Make sure that the formMessages div has the 'error' class.
        $(formMessages).removeClass('alert alert-success');
        $(formMessages).addClass('alert alert-danger');

        // Set the message text.
        if (data.responseText !== '') {
            $(formMessages).text(data.responseText);
        } else {
            $(formMessages).text('Oops! An error occured and your message could not be sent.');
        }
    });

});

});
