为什么jqgrid用php显示不了数据

[eloner]

<script type="text/javascript">
$(document).ready(
function() {
jQuery("#list").jqGrid({
url:'dt.php?q=2',
datatype: "json",
colNames:['编号','名称','主屏尺寸','操作系统','电池容量', '价格(￥)','操作'],
colModel:[
{name:'sn',index:'sn', width:80,align:'center'},
{name:'title',index:'title', width:180},
{name:'size',index:'size', width:120},
{name:'os',index:'os', width:120},
{name:'charge',index:'charge', width:100,align:'center'},
{name:'price',index:'price', width:80,align:'center'},
{name:'opt',index:'opt', width:80, sortable:false, align:'center'}
],
rowNum:10,
rowList:[10,20,30],
pager: '#pager',
sortname: 'id',
viewrecords: true,
multiselect: true,

sortorder: "desc",
caption:"手机产品列表"
});
jQuery("#list").jqGrid('navGrid','#pager',{edit:true,add:true,del:true});


});
</script>

PHP代码

$page = $_GET['page']; // get the requested page
$limit = $_GET['rows']; // get how many rows we want to have into the grid
$sidx = $_GET['sidx']; // get index row - i.e. user click to sort
$sord = $_GET['sord']; // get the direction
if(!$sidx) $sidx =1;
// connect to the database
$db = mysql_connect($dbhost, $dbuser, $dbpassword)
or die("Connection Error: " . mysql_error());

mysql_select_db($database) or die("Error conecting to db.");
$result = mysql_query("SELECT COUNT(*) AS count FROM products WHERE deleted=0");
$row = mysql_fetch_array($result,MYSQL_ASSOC);
$count = $row['count'];

if( $count >0 ) {
$total_pages = ceil($count/$limit);
} else {
$total_pages = 0;
}
if ($page > $total_pages) $page=$total_pages;
$start = $limit*$page - $limit; // do not put $limit*($page - 1)
$SQL = "SELECT * FROM products WHERE deleted=0 ORDER BY $sidx $sord LIMIT $start , $limit";
$result = mysql_query( $SQL ) or die("Couldn t execute query.".mysql_error());

$responce["page"] = $page;
$responce["total"] = $total_pages;
$responce["records"] = $count;
$i=0;
while($row = mysql_fetch_array($result,MYSQL_ASSOC)) {

$responce[rows[$i]['id']]=$row[id];
$opt = "<a href='edit.php'>修改</a>";
$responce[rows[$i]] = array (
$row['sn'],
$row['title'],
$row['size'],
$row['os'],
$row['charge'],
$row['price'],
$opt
);
$i++;
}
echo json_encode($responce);
