我创建了一个网站，用户现在可以成功登录，但根据用户所在的组，我希望在登录后将他们重定向到不同的页面。我有一个数据库，其中有一行"training_group"，例如，如果他们在组2013_1中，则在登录后会将他们定向到主页_20131.php。
我一直在网上寻找教程，并找到了一个带有开关功能的可能解决方案？但我不确定如何/在哪里实现这一点。我刚开始学习php，如果有任何建议，我将不胜感激！
现在，我的登录页面是这样的：
<?php
include 'core/init.php';
if (empty($_POST) === false) {
$username = $_POST['username'];
$password = $_POST['password'];
if (empty($username) === true || empty($password) === true) {
$errors[] = 'please input a username and password first! ';
} else if (user_exists($username) === false) {
$errors[] = 'We could not locate you in our database.';
}
$login = login($username, $password);
if ($login === false) {
$errors [] = 'That username/password combination is incorrect';
}
else {
$_SESSION['user_id'] = $login;
header('Location:logged_in/templates/logged_in_home.php');
exit ();
}
}
else {
$errors [] = 'No data received';
}
include 'includes/overall/header.php';
if (empty ($errors) === false) {
?>
<h2>We tried to log you in, but...</h2>
<?php
echo output_errors($errors);
}
include 'includes/overall/footer.php';
?>
以下是一些片段，它们可能会让您朝着正确的方向前进。
function login($username, $password){
//... your login code .. database call
if($validLogin){
$user_id = id from database;
$group_id = id from database;
$return = array('user_id' => $user_id, 'group_id' => $group_id);
}
else{
$return = false;
}
return $return;
}
$userinfo = login($username, $password);
if ($userinfo === false) {
$errors [] = 'That username/password combination is incorrect';
}
else {
$_SESSION['user_id'] = $userinfo['user_id'];
$_SESSION['group_id'] = $userinfo['group_id'];
$page = 'homepage_' . str_replace('_', '', $userinfo['group_id'] . '.php';
header('Location:' . $page);
exit ();
}
