            if(!isset($_GET["page"]) || $_GET["page"] == "home"){
                if(isset($_GET["txt"])){
                    include "search.php";
                }else{
                    include "content.php";
                }            
            }else if($_GET["page"] == "user" && $_GET["user"]){
                include "content_kategori.php"; 
            }else if($_GET["page"] == "kategori" && $_GET["kode"]){
                include "content_kategori.php"; 
            }else if($_GET["page"] == "full" && $_GET["kode"]){
