AJAX 联系表格 - 添加字段 + 多个表格一页

Question

所以我需要实现一个 AJAX 信息提交表单。我正在使用 Treehouse 的人构建的这个示例...... http://blog.teamtreehouse.com/create-ajax-contact-form

问题的第一部分……如何添加新字段？我试过编辑 .php .js 和 .html，让它们都符合我认为正确的内容，但在测试时我的解决方案失败了。

我需要的字段... 姓名：地点： Post代码：出生日期： URL Link: 留言（200字）：

第二部分……我可以运行两个在同一页上吗？

提前为任何帮助干杯！ - 如果你想让我发送代码等，你可以给我发邮件 garethyo@gmail.com

代码如下——

                <form id="ajax-contact" method="post" action="mailer.php">

                <div class="field">
                <label for="name">Name:</label>
                <input type="text" id="name" name="name" required>
                </div>

                <div class="field">
                <label for="email">Email:</label>
                <input type="email" id="email" name="email" required>
                </div>

                <div class="field">
                <label for="link">Link:</label>
                <input type="text" id="link" name="link" required>
                </div>


                <div class="field">
                <label for="message">Message:</label>
                <textarea id="message" name="message" required></textarea>
                </div>

                <div class="field">
                <button type="submit">Send</button>
                </div>

                </form>

JS

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

PHP

<?php
// My modifications to mailer script from:
// http://blog.teamtreehouse.com/create-ajax-contact-form
// Added input sanitizing to prevent injection

// 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 "Oops! There was a problem with your submission. Please complete the form and try again.";
        exit;
    }

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

    // Set the email subject.
    $subject = "A Future Bubbler… $name ";

    // Build the email content.
    $email_content = "Name: $name\n";
    $email_content .= "Email: $email\n\n";
    $email_content .= "Link: $link\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 "Oops! Something went wrong and we couldn't send your message.";
    }

} 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.";
}

?>

你永远不会定义 $link。您需要添加 $link = trim($_POST['link']);在 $message = trim($_POST["message"]); 之前。 – 肖恩 4 月 4 日 20:50
