我有一个用PHP处理的HTML表单。我想显示一条消息，让用户知道表单已成功提交。现在我不介意页面是否重新加载。我想要'成功'！表单提交后显示的消息。
任何帮助都会很棒！
PHP
<?php
$errors = array();
$missing = array();
if (isset($_POST['submit'])) {
$to = 'celinehalpin@hotmail.com';
$subject = 'Web Design';
$expected = array('name', 'company', 'email', 'phone', 'contactYou', 'interest', 'budget', 'comments');
$required = array('name', 'email', 'contactYou', 'interest', 'budget', 'comments');
$headers = "From: webmaster@example.com\r\n";
$headers .= "Content-type: text/plain; charset=utf-8";
$authenticate = '-fcelinehalpin@hotmail.com';
require './_includes/mail_process.php';
if ($mailSent) {
header('Location: index.php#c');
exit;
}
}
?>

而不是：
header('Location: index.php#c');
转到：
header('Location: ' . $_SERVER['REQUEST_URI'] . '?success=1');
然后添加：
if (isset($_GET['success'])) print 'Message sent!';

$_GET有效，但如果他们重新访问其历史记录中的链接（点击其历史记录，浏览器返回或刷新），它将始终存在
您可以在成功时设置$_SESSION，然后重定向到另一个页面（例如thanks.php）。
在thanks.php中，如果设置了会话，并且无论您希望什么标准，请回显它们与会话中的数据相关的任何消息。
然后取消设置会话。
这样，如果他们点击链接并返回到thanks.php页面，您的脚本将显示未设置的会话，因此可以生成一般信息：
此页面用于确认发送内容。你在这里和你一样 刷新页面或使用浏览器后退按钮。作为...的一部分 安全程序，我们清除数据一旦发送和确认等，
刷新thanks.php，弄乱GET数据等等，什么都不做。会话未设置，它们获得友好的通用消息。
