Answer 1

首先，试试这个：

$type = '';
if(isset($_POST['type'])):
    $type = $_POST['type'];
endif;
if($type != 'Semua'):
    $query_art = mysql_query("
    SELECT    * 
    FROM      artikel_tbl 
    WHERE     type = '$type' 
    ORDER BY  id") or die(mysql_error());
else:
    $query_art = mysql_query("
    SELECT    * 
    FROM      artikel_tbl 
    ORDER BY  id") or die(mysql_error());
endif;

使用组合框进行排序？
