Allowing users to Refresh browser without the "Confirm Form Resubmission" pop-up
提问by John
I have a login system, and while logged in, if I refresh the browser, Chrome shows a pop up window titled "Confirm Form Resubmission." I assume that the same thing would happen with other browsers.
我有一个登录系统，在登录时，如果我刷新浏览器，Chrome 会显示一个名为“确认表单重新提交”的弹出窗口。我认为其他浏览器也会发生同样的事情。
How can I allow the browser to be refreshed without this confirmation pop-up window? Of course, I would also like to stay logged in while refreshing the browser.
如何在没有此确认弹出窗口的情况下刷新浏览器？当然，我也想在刷新浏览器的同时保持登录状态。

After processing the POST page, redirect the user to the same page.
处理 POST 页面后，将用户重定向到同一页面。
On http://test.com/test.php
在 http://test.com/test.php
header('Location: http://test.com/test.php');
This will get rid of the box, as refreshing the page will not resubmit the data.
这将摆脱该框，因为刷新页面不会重新提交数据。

Alright, so at the top of you login page, you can just have this:
好的，所以在您登录页面的顶部，您可以拥有以下内容：
<?php
if (isset($_POST['username'])) {
// Do you login stuff here....
if ($passed == true) {
header('Location: index.php');
} else {
echo "Invalid username/password!";
}
