                    else if(item.dicek=="tidak")
                    {

                });
            },

<?php
session_start();
include "config.php";
$user=mysql_real_escape_string($_GET["id"]);
$result=mysql_query("SELECT * from filtering WHERE id_tenant='$user'") or die(mysql_error());

if (!empty($result))
{
    while ($row=mysql_fetch_array($result))
    {
        $tempfilter[] = $row['filter'];
        $q="select 'iya' as dicek,kategori.id_kategori,kategori.nama from kategori WHERE id_kategori  IN (".implode(',',$tempfilter).") UNION ALL select 'tidak' as dicek,kategori.id_kategori,kategori.nama from kategori where id_kategori  NOT IN (".implode(',',$tempfilter).") ";

        //echo $q;
        $result2 = mysql_query($q) or die(mysql_error());
        if (!empty($result2))
        {
            while ($row2=mysql_fetch_array($result2))
            {
                $fetchkategori[] = array
                (
                    'nama' => $row2['nama'],
                    'idkategori' => $row2['id_kategori'],
                    'dicek' => $row2["dicek"]
                );  
            }
        }

    }
}




mysql_close($con);

header('Content-Type:application/json');
echo json_encode($fetchkategori);
?>
