<div class="codebody" id="code19042">

if(empty($dopost))$dopost="";
//--------------------------------

if($dopost=="login")
{
if(empty($validate))$validate=="";
else$validate=strtolower($validate); if(empty($_SESSION["s_validate"]))$svali="";
else$svali=$_SESSION["s_validate"]; $cuserLogin=newuserLogin();
if(!empty($userid)&&!empty($pwd))
{
$res=$cuserLogin->checkUser($userid,$pwd);
