问题描述
我正在尝试使用 header() 函数来创建重定向.我想显示错误消息.目前我正在通过 URL 作为参数发送消息，但这使它看起来很丑陋.
I'm trying to use the header() function to create a redirect. I would like to display an error message. Currently I'm sending the message as a parameter through the URL, however this makes it look quite ugly.
有没有办法将此值作为后变量传递?
Is there a way to pass this value as a post variable instead?
感谢任何建议.
谢谢.
推荐答案
Dan，您可以在 PHP 中启动和存储会话，然后将消息保存为会话变量.这使您不必在 HTTP 请求中传输消息.
Dan, You could start and store a session in PHP then save the message as a session variable. This saves you from having to transfer the message in an HTTP request.
//Start the session
session_start();
//Dump your POST variables
$_SESSION['POST'] = $_POST;
//Redirect the user to the next page
header("Location: bar.php");
现在，在 bar.php 中，您可以通过重新启动会话来访问这些 POST 变量.
Now, within bar.php you can access those POST variables by re-initiating the session.
//Start the session
session_start();
//Access your POST variables
$temp = $_SESSION['POST'];
//Unset the useless session variable
unset($_SESSION['POST']);
要了解有关会话的更多信息，请查看:http://php.net/manual/en/function.session-start.php
