Hi could you please check this code ad tell me why it doesn't work. It doesn't check the IP it just blocks the user!

functions_user.php

// REGIP = new param
        $query = $db->simple_select("users", "uid,username,password,salt,loginkey,usergroup,regip", "uid='".intval($uid)."'", array('limit' => 1));
        $user = $db->fetch_array($query);
    }
    if(!$user['salt'])
    {

member.php

elseif($user['usergroup'] == X || $user['usergroup'] == Y)
        {
            $currentip = $_SERVER['REMOTE_ADDR'];
            if ($currentip != $user['regip'])
             {
               $errors[] = "Cannot log you in!";
             }
        }

X and Y is where I put group ID
