ถ้าต้องการให้ แสดงข้อมูลเรียงตามวันที่ด้วย ต้องเพิ่ม code ยังไงบ้างครับ

<? include "include/config.inc.php";
					 if($id_new!=""){
	$sql = "select * from tbl_new where id_new='$id_new' ORDER BY date DESC"; 
		}else $sql = "select * from tbl_new"; 
$dbquery = mysql_db_query($dbname, $sql);
while ($n < 6)
{
    //$id_new = $result[id_new];
	$result = mysql_fetch_array($dbquery);
	$top_new = $result[top_new];
	$rest = substr("$top_new", 0, 25); 

	$n++; ?>

<? include "include/config.inc.php"; 
                     
$tbl_new="tbl_new";
$sql="Select * From $tbl_new order by date DESC limit 6";
$db_query=mysql_query($sql);
$i=0;
while($result=mysql_fetch_array($db_query))
{
	$top_new = $result[top_new];     
	$rest = substr("$top_new", 0, 25);  
$i++;
?> 
<table width="500" border="0" align="center" cellpadding="0" cellspacing="0">
  <tr>
    <td><a href="detailnew.php?id_new=<?=$result[id_new];?>"><?=$rest;?></a></td>
