第一次查询能成功，假如我要对查询结构分页，我如何保存率选值呢？
不知道各位对我提的问题明白否？请高手指点！
<?
$cwhname=$_POST['cwhname'];
$currentstock=$_POST['currentstock'];
if($currentstock and !$cwhname){
$querygb="select * from $dbtable where currentstock>='".$_POST['currentstock']."'";
}
elseif($cwhname and !$currentstock){
$querygb="select * from $dbtable where cwhname='".$_POST['cwhname']."'";
}
elseif($currentstock and $cwhname){
$querygb="select * from $dbtable where cwhname='".$_POST['cwhname']."'and currentstock>='".$_POST['currentstock']."'";
}
else
{
echo '请选择查询条件';
exit();
}

//$querygb="select * from $dbtable where cwhname='".$_POST['cwhname']."'and currentstock>='".$_POST['currentstock']."'";
$resgb = mssql_query($querygb);
$count=mssql_num_rows($resgb);
if(!isset($_GET['listnum']))$listnum=20;
else $listnum=$_GET['listnum'];
$pagecount=ceil($count/$listnum);
if(!($row[0] = mssql_fetch_row($resgb))) die("没有符合条件的记录!");
for($i=1;$i<$count;$i++)
{$row[$i] = mssql_fetch_row($resgb);
}
if(!isset($_GET['page']))
{ $page=1;
}
else
{ $page=$_GET['page'];
}
$prepage=$page-1;
$nextpage=$page+1;

for($i=($page-1)*$listnum;$i<$page*$listnum;$i++)
{if($page==$pagecount)
{
if(!isset($row[$i])) break;
}
