我有一个问题,用户无法注销,因为 $_COOKIE 并没有真正删除。我无法找出可能是什么问题。
此代码仅在登录时使用一次:
// Log In
$_SESSION['user_id'] = $row['user_id'];
$_SESSION['username'] = $row['username'];
setcookie('user_id', $row['user_id'], time() + 2592000);
setcookie('username', $row['username'], time() + 2592000);
下面的代码检查是否设置了 cookie 以使用户在重新启动浏览器时登录(“保持登录”效果)。
// Starting Session
session_start();
// If the session vars aren't set, try to set them with cookies
if (!isset($_SESSION['user_id'])) {
// This check always equals true because cookies are not deleting on Log Out
if (isset($_COOKIE['user_id']) && isset($_COOKIE['username'])) {
$_SESSION['user_id'] = $_COOKIE['user_id'];
$_SESSION['username'] = $_COOKIE['username'];
}
}
此代码仅在注销时启动一次:
// Log Out
session_start();
if (isset($_SESSION['user_id'])) {
$_SESSION = array();
if (isset($_COOKIE[session_name()])) {
setcookie(session_name(), '', time() - 2592000, '/');
}
session_destroy();
}
setcookie('user_id', '', time() - 2592000);
setcookie('username', '', time() - 2592000);
