vB did not load Language properly

[Hoffi]

I build an own solutuion for a User sharing between vB and an own Portal-System with its own User-Database.

No we changed the File class_core.php, so that the class vB_Session looks for special Cookies and checks the Data against the vB Database. If a user is found the System sets via Datamanager the new Data oder a new User is created.

Then I set the Sessions, but everytime the first load of the Site it seems that no language is found if a user is logged in. During Logout the first time the User-Data is present.

Everytime after the second load everything is OK.

Here my Code after the Userdata loading from the API. If I did nout a User or the Datamanager cant't create e New one, the ID is -1 and a new Guest-Session must be started.

PHP Code:

            $this->vars =& $session;
            $this->created = false;
            if ($userid > 0)
            {
                $gotsession = true;
                $useroptions = (defined('IN_CONTROL_PANEL') ? FETCH_USERINFO_ADMIN : 0) + (defined('AVATAR_ON_NAVBAR') ? FETCH_USERINFO_AVATAR : 0);
                $userinfo = fetch_userinfo($userid, $useroptions, $languageid);
                $this->vars = $this->fetch_session($userid);
                $this->created = true;

                $this->userinfo =& $userinfo;
            }
            elseif ($userid == -1)
            {
                $gotsession = true;
                $this->vars = $this->fetch_session(0);
                $this->created = true;

                $this->userinfo =& $userinfo;
            } 


Where is my error? Has someone an idea?

--------------- Added [DATE]1254213501[/DATE] at [TIME]1254213501[/TIME] ---------------

Whow, I solved the Problem.

The Issue was, that the function verify_id sets a Variable in $vbphrase (I have no Idea, why!, and so fetch_userinfo() did not load the Language-Settings.

The Problem was, that the function verify_id() sets an Field into $vbphrase which is not initialized this time. So fetch_userinfo() did not load the language Settings.

Does anybody have an idea why the function sets the array?

PHP Code:

    if (empty($vbphrase["$idname"]))
    {
        $vbphrase["$idname"] = $idname;
    } 


Whats the reason for this code?
