请教DWZ PHP网站后台换页问题

本帖最后由 gdljw 于 2013-03-30 11:45:59 编辑最后搞PHP+DWZ做网站后台，网上找到这代码，试用正常可以换页,但是我想加一个条件caidid=caidid分页，直接在$sql= "select id,u_id,u_name,last_logintime,last_ip,last_imei,last_phone_number,last_logintype from users where CateId='$CateId2' and $tiaojian like '%$neirong%' order by $orderField {$orderDirection} limit {$fup_page},{$numPerPage}";

就换不了页了，请问要怎设置？

 require_once '../include/config.php';
$connect = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD)
                or die('Could not connect to mysql server.');

        mysql_select_db(DB_DATABASE, $connect)
                or die('Could not select database.');
?>

echo '

';
//定义条件sql

$CateId = get_CateId_by_UId( $UId );
$tiaojian = empty($_POST["tiaojian"])?'u_name':$_POST["tiaojian"];
$neirong = empty($_POST["keywords"])?"":$_POST["keywords"];
$CateId2 = empty($_POST["CateId2"])?'CateId':$_POST["CateId2"];
$orderField = empty($_POST["orderField"])?"id":$_POST["orderField"];
$query = mysql_query("select * from users");
$totalCount = mysql_num_rows($query);
$pageNumShown=10;
$_POST["pageNum"]!=""?$pageNum=$_POST["pageNum"]:$pageNum=1;
$numPerPage=empty($_POST["numPerPage"])?20:$_POST["numPerPage"];
$fup_page=($pageNum-1)*$numPerPage;
$sql= "select id,u_id,u_name,last_logintime,last_ip,last_imei,last_phone_number,last_logintype from users where $tiaojian like '%$neirong%' order by $orderField {$orderDirection} limit {$fup_page},{$numPerPage}";
$result = mysql_query($sql);
?>
