Question

我正在尝试创建一个ajax函数，允许我的网站在不刷新页面的情况下向我发送消息。但不知怎的，我无法做到这一点，因为每次点击它，我都会在控制台中收到此错误：

无法加载资源：服务器响应状态为500（内部服务器错误）。

这是我的剧本：

$(function() {

var form = $('#ajax-contact');

var formMessages = $('#form-messages');


$(form).submit(function(event) {
    event.preventDefault();

    var formData = $(form).serialize();

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

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

        // Clear the form.
        $('#name').val('');
        $('#email').val('');
        $('#message').val('');
    }).fail(function(data) {
        // Make sure that the formMessages div has the 'error' class.
        $(formMessages).removeClass('success');
        $(formMessages).addClass('error');

        // 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.');
        }
    });
});


});

这是我的PHP文件：

<?php

// Only process POST reqeusts.
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Get the form fields and remove whitespace.
    $name = strip_tags(trim($_POST["name"]));
            $name = str_replace(array("\r","\n"),array(" "," "),$name);
    $email = filter_var(trim($_POST["email"]), FILTER_SANITIZE_EMAIL);
    $message = trim($_POST["message"]);

    // Check that data was sent to the mailer.
    if ( empty($name) OR empty($message) OR !filter_var($email, FILTER_VALIDATE_EMAIL)) {
        // Set a 400 (bad request) response code and exit.
        http_response_code(400);
        echo "All fields must be filled.";
        exit;
    }

    // Set the recipient email address.
    // FIXME: Update this to your desired email address.
    $recipient = "example@example.com";

    // Set the email subject.
    $subject = "New Message from $name";

    // Build the email content.
    $email_content = "Name: $name\n";
    $email_content .= "Email: $email\n\n";
    $email_content .= "Message:\n$message\n";

    // Build the email headers.
    $email_headers = "From: $name <$email>";

    // Send the email.
    if (mail($recipient, $subject, $email_content, $email_headers)) {
        // Set a 200 (okay) response code.
        http_response_code(200);
        echo "Thank You! Your message has been sent.";
    } else {
        // Set a 500 (internal server error) response code.
        http_response_code(500);
        echo "Something went wrong.";
    }

} else {
    // Not a POST request, set a 403 (forbidden) response code.
    http_response_code(403);
    echo "There was a problem with your submission, please try again.";
}

?>

Answer 1

首先猜测

邮件功能返回false，您将收到错误500页。

尝试删除http_response_code(500);

如果结果没有改变。检查服务器日志。

在这种情况下，在第二行添加error_reporting(E_ALL);可能有所帮助，具体取决于您的服务器配置。

Answer 2

你需要逐一将die('test')放在每一行......

开始调试

从第一行开始死...如果你在控制台中得到模具按摩然后从该行中移除模具并放入下一行...按照此调试步骤直到找到php错误行...因为我确定代码中必定存在一些PHP错误...这会导致500服务器错误......
