当 JavaScript 被禁用时，我的表单出现问题：

  • 表单从页面 index.php 提交
  • 收件人收到的表格
  • 挂在 include.emailSender.php

返回原始页面我缺少什么？从网页到流程表单的代码：

<?php include_once('includes/include.contactForm.php'); ?>

include.emailSender.php 文件：

<?php


$contactformRecipient = 'a@b.org';


$contactformTitle = 'Contact from ...';


if($_POST) {
    $contactName = addslashes( $_POST['contactName'] );
    $contactEmail = addslashes( $_POST['contactEmail'] );
    $contactPhone = addslashes( $_POST['contactPhone'] );
    $contactMessage = addslashes( $_POST['contactMessage'] );


    $message = '';
    $message .= 'Name:  ' . $contactName . '<br />';
    $message .= 'Email:  ' . $contactEmail . '<br />';
    $message .= 'Phone:  ' . $contactPhone . '<br />';
    $message .= 'Message:  ' . $contactMessage . '<br />';



    // Email Headers
    $headers = "From: " . $contactEmail . "\r\n";
    $headers .= "Reply-To: ". $contactEmail . "\r\n";
    $headers .= "MIME-Version: 1.0\r\n";
    $headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";

    // send mail
    // mail( to, subject, message, headers, parameters)
    mail( $contactformRecipient, $contactformTitle, $message, $headers );
}

?>

include.contactForm.php 文件：

<?php 
$randomNumber1 = rand(1, 12);
$randomNumber2 = rand(1, 12);

$contactCaptchaAnswer = $randomNumber1 + $randomNumber2;
?>
            <div id="contact-warning">
            </div><!-- // #contact-warning -->

            <div id="contact-success">
                Email successfuly sent, thank you.<br />    
            </div><!-- // #contact-warning -->

            <form name="contactForm" id="contactForm" method="post" action="includes/include.emailSender.php">
                <fieldset>

                    <label for="contactName">Your Full Name <span class="required">*</span></label>
                    <input name="contactName" type="text" id="contactName" size="60" value="" />

                    <label for="contactPhone">Phone <span class="required">*</span></label>

                    <label for="contactMessage">Message <span class="required">*</span></label>
                    <textarea name="contactMessage" id="contactMessage" rows="6" cols="7"></textarea>

                    <br />
                    <label for="contactCaptcha"><strong><?php echo $randomNumber1; ?></strong> + <strong><?php echo $randomNumber2; ?></strong> = <span class="required">*</span></label>

                </fieldset>
            </form>

现在我没有阅读你所有的代码，而是我想给你一些关于何时使用 AJAX:ing 表单或其他东西的提示。

与其先构建表单的 JavaScript + AJAX 版本，不如从纯版本开始。可以在全球所有类型设备上的浏览器中运行的版本。

完成后，您就可以使用该表格。使用 jQuery 和 jQuery 表单插件 ( http://www.malsup.com/jquery/form/ ) 再简单不过了。假设您已经设置了表单：

<form method="post" action="some-action.php" id="my-form">
    <p><label>Some field<br><input type="text" name="foo"></label></p>
    <p><input type="hidden" name="bar" value="1"><input type="submit" value="Go"></p>
</form>

并且您已经确保some-action.php正确处理表单提交（没有 AJAX）然后简单地：

$('#my-form').ajaxForm(function (data) {
    alert(data); // data returned by some-action.php
});

some-action.php现在，如果您想根据是否是 AJAX 调用来做不同的事情（例如，您可能希望重定向回非 AJAX 调用的上一页），您可以简单地检查$_SERVER['HTTP_X_REQUESTED_WITH']，我通常会这样做（您保留常量的地方） ：

define('XHR', (
    isset($_SERVER['HTTP_X_REQUESTED_WITH']) and 
    strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest'
));

然后稍后在some-action.php：

if (XHR) {
    die(json_encode(array('success' => true)));
}
else {
    header('Location: ' . $_SERVER['http_referer']);
}

所谓的渐进增强（最纯版本优先）优于优雅降级（最高级版本优先）的好处与移动优先设计的好处相同。它们都在其他地方得到更好的解释，比如 Brad Frost 的博客：http ://bradfrostweb.com/blog/web/mobile-first-responsive-web-design/
