我的页面上有一个PHP表单，如下所示-
<?php
if(isset($_POST['email'])) {
// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "someone@somewhere.com";
$email_subject = "subject";
function died($error) {
// your error code can go here
echo "We are very sorry, but there were error(s) found with the form you submitted. ";
echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
die();
}
// validation expected data exists
if(!isset($_POST['first_name']) ||
!isset($_POST['last_name']) ||
!isset($_POST['email']) ||
!isset($_POST['telephone']) ||
!isset($_POST['comments'])) {
died('We are sorry, but there appears to be a problem with the form you submitted.');
}
$first_name = $_POST['first_name']; // required
$last_name = $_POST['last_name']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['telephone']; // not required
$comments = $_POST['comments']; // required
$error_message = "";
$email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email_from)) {
$error_message .= 'The Email Address you entered does not appear to be valid.<br />';
}
$string_exp = "/^[A-Za-z .'-]+$/";
if(!preg_match($string_exp,$first_name)) {
$error_message .= 'The First Name you entered does not appear to be valid.<br />';
}
if(!preg_match($string_exp,$last_name)) {
$error_message .= 'The Last Name you entered does not appear to be valid.<br />';
}
if(strlen($comments) < 2) {
$error_message .= 'The Comments you entered do not appear to be valid.<br />';
}
if(strlen($error_message) > 0) {
died($error_message);
}
$email_message = "Form details below.nn";
function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}
$email_message .= "First Name: ".clean_string($first_name)."n";
$email_message .= "Last Name: ".clean_string($last_name)."n";
$email_message .= "Email: ".clean_string($email_from)."n";
$email_message .= "Telephone: ".clean_string($telephone)."n";
$email_message .= "Comments: ".clean_string($comments)."n";
// create email headers
$headers = 'From: '.$email_from."rn".
'Reply-To: '.$email_from."rn" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);
?>

我希望当点击提交按钮时，成功行在页面上显示为对话框，而不是新页面。不幸的是，如果无法做到这一点，那么有没有办法对点击提交按钮后的文本(成功行)进行风格化？提前谢谢，请帮忙。
是的，这是可能的。
1) 在表单上创建一个隐藏的div
2) 在主窗体上创建一个指向ajax调用的链接。在您希望传输到您希望返回的web服务器/数据服务器的链接上包含记录密钥信息。
3) 在附加的.js文件中创建ajax调用和响应。在ajax调用查询中，将查找的密钥发送到服务器端响应php应用程序。
4) 在服务器端创建一个php响应应用
5) 你的服务器端应用程序会查找记录信息，并通过一个简单的"echo"命令发回。
6) 然后，您的客户端应用程序将接收信息。在ajax调用的响应部分，将检索到的信息添加到隐藏中，并使其可见。
7) 在弹出窗口上添加一个"关闭"链接以重新隐藏弹出窗口。
我建议您通过JSON发送信息。这在客户端和服务器的每一侧都很容易，只需为每一侧添加一行"编码"one_answers"解码"即可。
由于这是要显示的大量示例代码，如果其中有部分需要帮助，只需针对需要帮助的代码部分发布这些特定问题即可。
