ช่วยทีครับ ทำระบบเสิทแล้วแบบ จอยเทเบิ้ล แต่ค้นได้แต่หัวข้อครับ

$sql_count="SELECT count(id) FROM tb_k2_items WHERE title LIKE '%$kw%';
$db->setQuery($sql_count);
$rs = $db->LoadObjectList();
$per_page=5;
$count = $rs[0][0];
$all_page=ceil( $count / $per_page );
$page = 1; // แล้วแต่กำหนด ส่งค่ามาเซท
$start_row = ($page - 1) * $per_page;
$qr="
SELECT cate.id, cate.name, cate.description
, item.id item_id, title, introtext, `fulltext` 
FROM (
	SELECT id, catid, title, introtext, `fulltext` 
	FROM tb_k2_items 
	WHERE title LIKE '%".$kw."%' 
) as item
LEFT JOIN tb_k2_categories cate
ON cate.id=item.catid
limit $start_row, $per_page
";

<?php 
								foreach ($this->FullSearchListLv1 as $item): 
								
								$db = JFactory::getDbo();
								$sql = "SELECT * FROM tb_menu 
										WHERE menutype='ttdmainmenu'
