If isset $_SESSION goto this page?
提问by eberswine
Ok, having trouble here:
好的，这里有问题：
I created a login script, so after a person logs in then they will get direted to another page. And also, I have it redirecting them to the login page if they try and access one of those other pages.
我创建了一个登录脚本，所以在一个人登录后，他们会被引导到另一个页面。而且，如果他们尝试访问其他页面之一，我会将他们重定向到登录页面。
My problem is, if a user is logged in and stumbles to the login page again --by accident-- I would like for it to recognize that the user is logged in and redirect them to that next page (which is index2.php) ?? Having troubles :-(
我的问题是，如果用户登录并再次跌跌撞撞地进入登录页面——不小心——我希望它能够识别出用户已登录并将他们重定向到下一个页面（即 index2.php） ?? 遇到麻烦:-(
Here is my code so far:
到目前为止，这是我的代码：
require_once "inc/functions.class.php";
$quickprotect = new functions('inc/ini.php');
if (isset($_SESSION['goAfterLogin'])){
$goto = $_SESSION['goAfterLogin'];
unset($_SESSION['goAfterLogin']);
}
else $goto = $quickprotect->settings['DEFAULT_LOGIN_SUCCESS_PAGE'];
if (isset($_POST[username])) {
if($quickprotect->login($_POST[username], $_POST[password])) header ("Location: $goto");
}
Here is how I store a users session in the functions page
这是我在功能页面中存储用户会话的方式
public function is_logged_in() {
//Determines if a user is logged in or not. Returns true or false;
if ($_SESSION['logged_in'] === md5($this->settings[ADMIN_PW])) {
return true;
}
else return false;
}

You don't mention how you store your users in your session, but something like this should do it for you:
您没有提到如何在会话中存储用户，但是这样的事情应该为您做：
if(isset($_SESSION['user']))
{
header("Location: index2.php");
exit;
}
This will check if you have a user in your session, and if so, redirect to index2.php.
这将检查您的会话中是否有用户，如果有，则重定向到index2.php.
You need to change 'user'according to your session key.
您需要'user'根据您的会话密钥进行更改。
