这是我在本网站的第一篇文章，希望有人可以提供帮助。
我有一个简报注册系统。表单调用处理脚本，但在运行时，它会输出到另一个页面。
我希望它在同一页面上处理，并输出相应的消息。
经过一些研究，我能找到的壁橱是这篇文章：similar question
以下是我正在使用的代码：
HTML
<h6 class="mailingHeadine">Join Our Mailing List</h6>
<!-- start newsletter -->
<form id="mailing_list" name="mailing_list" action="<?php echo $_SERVER['PHP_SELF'] ?>" method="POST" >
<!-- start maillist -->
<div class="maillist">
<input type="text" id="e_mail" name="e_mail" value="Enter Your Email" onfocus="if(this.value=='Enter Your Email')this.value=''; this.className='email'" onblur="if(this.value=='')this.value='Enter Your Email'; this.className='email'" />
<p class="submit"><button type="submit" name="e_submit" value="Subscribe" id="submit">Join</button></p>
</div><!-- end maillist -->
</form><!-- end newsletter -->
<div id="formResponse" style="display: none;"></div>
IN PAGE SCRIPT
<script type="text/javascript">
$("#mailing_list").submit(function() {
$.post('link-to-script.php', {email: $('e_mail').val(), e_submit: 'yes'}, function(data) {
$("#formResponse").html(data).fadeIn('100');
$('#e_mail').val(''); /* Clear the inputs */

return false;
});

它只是有点工作。它运行PHP脚本并始终输出“您必须有一个电子邮件地址才能订阅新闻稿”，这是PHP代码中的最后一行。
非常感谢任何帮助。

一些事情。
首先，您的PHP文件应该只是PHP - 没有HTML。此时，不要尝试将包含PHP的另一个HTML页面混合为PHP ajax处理器文件。这很棘手，不推荐。
我没有麻烦你的PHP页面，只是把它缩小到了或许应该是：
<?php
include('e-includes/loader.php');
include('e-head.php');
if(defined('SMTP') && SMTP == 'true') {
include('e-includes/class.phpmailer.php');
}
if(isset($_POST['e_submit']) && strlen($_POST['e_mail']) !== 0) {
// The system settings
include('e-includes/settings.php');
// grab the user email
$email = $_POST['e_mail'];
// validate the email
if(substr_count($email,'@') == 1 && substr_count($email,'.') >= 1) {
// check if user is already subscribed - avoids duplications
$results = $easyLetters->checkSubscription($email);
// subscribe the user
if(empty($results)) {
$subscribe_user = $easyLetters->subscribeUser($email);
// Notify Admin that an user as been subscribed
if($subscribe_user) {
if($options['easyLetters_notifications'] == 'subscriptions' || $options['easyLetters_notifications'] == 'both') {
$subject = 'Subscription Notification ID-'.mt_rand(0, 5).': Subscription for: '.$email;
$message = str_replace('{EMAIL}', $email, $options['easyLetters_notification_message']);
$message_send = str_replace('{ACTION}', $translate->__('cancels subscription'), $message);
if(defined('SMTP') && SMTP == 'false') {
$from = $options['easyLetters_email'];
$headers = "From: {$from}\r\n";
$headers .= "X-Mailer: easyLetters\r\n";
$headers .= "Content-Type: text/html; charset=utf-8";
if($subscribed) {
@mail($from, $subject, $message_send, $headers);
}
} elseif(defined('SMTP') && SMTP == 'true') {
$mail = new PHPMailer;
$mail->IsSMTP();
$mail->Host = SMTP_HOST;
if(defined('SMTP_AUTH') && SMTP_AUTH == 'true') {
$mail->SMTPAuth = true;
$mail->Username = SMTP_USERNAME;
$mail->Password = SMTP_PASSWORD;
} else {
$mail->SMTPAuth = false;
}
$mail->From = $options['easyLetters_email'];
$mail->FromName = 'EasyLetters';
$mail->IsHTML(true);
$mail->Subject = $subject;
$mail->AddAddress($options['easyLetters_email']);
$mail->Body = $message_send;
}
}
echo '
<div class="alert alert-success tac">
<img src="e-images/done.png" width="48" height="48" alt="done"/>
<p>Thank you for subscribing to our Newsletter.</p>
</div>
';
} else {
echo '
<div class="alert alert-error tac">
<img src="e-images/failed.png" width="48" height="48" alt="failed"/>
<p>Error occured while subscribing you.</p>
</div>
';
}
} else {
echo '
<div class="alert alert-error tac">
<img src="e-images/failed.png" width="48" height="48" alt="failed"/>
<p>You are already subscribed to our newsletter.</p>
</div>
';
}
} else {
?>
<div class="alert alert-error tac">
<img src="e-images/failed.png" width="48" height="48" alt="failed"/>
<p>Invalid E-mail Address</p>
</div>
}
} else {
<div class="alert alert-error tac">
<img src="e-images/failed.png" width="48" height="48" alt="failed"/>
<p>You must have an e-mail address in order to subscribe to newsletter</p>
</div>
}
请注意顶部只有一个<?php标记。这就是你所需要的一切。所有其余的都是PHP，并且回显的HTML将作为文本字符串返回。
现在，如果您在AJAX成功函数中没有收到正确的响应，那么您将需要对PHP程序逻辑进行故障排除。首先用以下代码替换整个PHP文件：
<?php
die("I am here");
并修改您的AJAX代码块以显示返回的内容：
$.post('http://www.american-designer.com/t/News/e-subscribe.php', {email: $('e_mail').val(), e_submit: 'yes'}, function(data) {
alert( data );
}, 'text');
最后请注意，$.post()，$.get()，$.load()都只是完整ajax构造的简写版本：$.ajax()。就个人而言，我发现$ .post更难以使用。
我建议你多读一些关于AJAX的内容：
答案 1 :(得分：0)
我会以Jquery的形式推荐Ajax来处理相同的页面请求。 Ajax将允许您调用服务器，运行代码并将响应返回给客户端，而无需离开页面甚至重新加载它。您需要先使用以下命令将库添加到页面中：
<script src="http://code.jquery.com/jquery-2.1.1.min.js" ></script>
接下来，您需要确保在加载页面之前代码不会运行。使用：
$(document).ready(function(){
//your code will be going here
});
现在我们使用jquery的onclick（）版本调用php页面：
$(document).ready(function(){
$("#your_submit_button_id").click(function(){ //when you click the element having that particular id, we execute the function listed.
});
});
好吧最后我们必须对php页面进行ajax调用并获得结果。
$(document).ready(function(){
$("#your_submit_button_id").click(function(){ //when you click the element having that particular id, we execute the function listed.
$.ajax({
url: "your_file.php",
type: "POST",
dataType: "xml", //return type, can be xml, html, or json
data: {email: "whatever"}, //this is the data you are sending, you'll have to add some code to get the value of the input. format is: variable_name: "value"
success: function(data_returned_from_php){
//whatever you decide to echo bakc will be in data_returned_from_php or whatever you decide to call the object
//take the data you get back and do whatever the hell you want with it.
}
});
});
});
页面不会重新加载，但返回的数据可以附加到页面，或者您可以制作并警告（）

好的，所以我想出来以防其他人有兴趣。
<script type="text/javascript">
$("#mailing_list").submit(function() {
$.post('link to script here.php', {e_mail: $('#e_mail').val(), e_submit: 'Subscribe'}, function(data) {
$("#formResponse").html(data).fadeIn('100');
$('#e_mail').val(''); /* Clear the inputs */
}, 'text');
return false;
});
</script>
我错过了第二个值“e_submit”，提交按钮的名称以及我需要传递的“值”。
