更简单、更安全的查询方法

//另一种更安全的方法，且解决了查询，分页的问题，以后都应该用这种方法来做

publicfunction manage($n) {

        $tab = M($n);

        $Bigtitle = I(‘Bigtitle‘);

        $Publishtime = I(‘Publishtime‘);

        $page = isset($_POST[‘page‘]) ?intval($_POST[‘page‘]) : 1;

        $rows = isset($_POST[‘rows‘]) ?intval($_POST[‘rows‘]) : 10;

        $offset = ($page - 1) * $rows;

        $sql[‘Lixiao‘] = ‘否‘;

        $sql[‘SchoolID‘] ="$_SESSION[SchoolID]";

        if ($Bigtitle != ‘‘) {

            $sql[‘Bigtitle‘] ="$Bigtitle";

        }

        if ($Publishtime != ‘‘) {

            $sql[‘Publishtime‘] ="$Publishtime";

        }

        $sql[‘_logic‘] = ‘AND‘;

        $total =$tab->where($sql)->count();

        $rs =$tab->where($sql)->limit($offset, $rows)->select();

        if (!isset($rs)) {

            $json->total = 0;

            $json->rows = array();

        } else {

            $json->total = $total;

            $json->rows = $rs;

        }

        $this->ajaxReturn($json);

    }
