关于jqgrid的问题
一。本地测试可以显示数据库数据，上传到服务器上就显示不了，sql都在phpmyadmin测试过，可以用的，请问怎么查是什么原因。
二。编码问题，页面本来编码为GB的，我把sale_list.html和do.php用记事本转成utf-8后，本地测试jqgrid就显示不了数据。
do.php源码
<?phpinclude_once ("conn.php");$action = $_GET['action'];switch ($action) { case 'list' : //列表 $page = $_GET['page']; $limit = $_GET['rows']; $sidx = $_GET['sidx']; $sord = $_GET['sord'];// $page = 1;// $limit = 12;// $sidx = 'id';// $sord = 'asc'; if (!$sidx) $sidx = 1; $where = ''; $product_name = uniDecode($_GET['product_name'],'utf-8'); if(!empty($product_name)) $where .= " and `product-name` like '%".$product_name."%'"; $order_id = uniDecode($_GET['order_id'],'utf-8'); if(!empty($order_id)) // $where .= " and order_id='$order_id'"; $where .= " and `order_id` like '%".$order_id."%'"; //$result = mysql_query("SELECT COUNT(*) AS count FROM products where deleted=0".$where); $result = mysql_query("SELECT COUNT(*) AS count FROM `sale_orders` WHERE `number`>0".$where); $row = mysql_fetch_array($result, MYSQL_ASSOC); $count = $row['count']; //echo $count; if ($count > 0) { $total_pages = ceil($count / $limit); } else { $total_pages = 0; } if ($page > $total_pages) $page = $total_pages; $start = $limit * $page - $limit; if ($start<0) $start = 0; $SQL = "SELECT * FROM `sale_orders` WHERE `number`>0".$where."

楼主的数据库编码是什么呀，必须和页面统一哦。
qGrid 是一个用来显示网格数据的jQuery插件
传递给他的数据应该是 json，你就简单的
echo $page;
echo $limit;
echo $sidx;
echo $sord;
算什么?
echo $page;
echo $limit;
echo $sidx;
echo $sord;
因为后面两个变更我不知道什么意思，所以想输出一下看看
