如何从数据库获取用户ID到arrowchat集成

Question

在我的php中我有这段代码，看看用户是否已登录

$auth=new auth();
$username = $auth->loggedIn();
global $crt_usr;
if(!$username) { header("Location: ".$config_live_site."/login.php?loc=account_info.php"); exit(0); }
$smarty->assign("username",$username);

$usr = new users();
$user = $usr->getUser($crt_usr);
$smarty->assign("user",$user);

我有和这个插入箭头

function get_user_id() 
{
    $userid = NULL;

    if (isset($_COOKIE['userid']))
    {
        $userid = $_COOKIE['userid'];
    }

    return $userid;
}

我的数据库中的用户ID字段名称是＆＃34; id＆＃34;

您可以设置具有您的用户ID的会话并将其放入get_user_id()函数

if (isset($_SESSION['userid']))
{
    $userid = $_SESSION['userid'];
}
