请问DWZPHP网站后台换页有关问题

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);

?>
