$typeId=$_GET['typeId'];
$typeName=$_POST['typeName'];
$newsTypes=NewsTypes::getNewsTypes();
if ($act=="delete") {
$result=NewsTypes::delNewsType($typeId);
header("location:success.php?act=deltype&rst={$result}");
}else if($act=="update"){
$result=NewsTypes::updateNewsType($typeId,$typeName);
header("location:success.php?act=modtype&rst={$result}");
}
$smarty->assign("newsTypes",$newsTypes);
$smarty->assign("typeId",$typeId);
$smarty->assign("typeName",$typeName);
$smarty->display('modtype.html');
