thinkphp分页和筛选功能并存

栏目：php教程时间：2014-08-28 21:34:19

当分页与筛选功能并存时，刚开始只使用了一个判断。发现筛选的特定属性的列表的第二页无法正常显示。第二页会自动跳出为没有筛选的页面。后来发现在模板中设置一个开关，并加以判断就可以解决。

$switch = I('switchs');

        if($switch == 1){

        $book_id = I('cate');

        $_SESSION['book_id']=$book_id;}

        if($_SESSION['book_id']!=0){

                  $total = D('BookPostView')->where(array('status'=>1,'book_id'=>$_SESSION['book_id']))->count();

                  $Page = new \Think\Page($total,10,array(),'','id','');

                  $Page->setConfig('theme', '%FIRST% %UP_PAGE% %LINK_PAGE% %DOWN_PAGE% %END%  ');

                  $page = $Page->show();

                  $this->assign('page', $page);

                  $list  = D('BookPostView')->where(array('status'=>1,'book_id'=>$_SESSION['book_id']))->limit($Page->firstRow . ',' . $Page->listRows)->order('id desc')->select();

        }else{

            $total = D('BookPostView')->where(array('status'=>1))->count();

            $Page = new \Think\Page($total,10,array(),'','id','');

            $Page->setConfig('theme', '%FIRST% %UP_PAGE% %LINK_PAGE% %DOWN_PAGE% %END%  ');

            $page = $Page->show();

            $this->assign('page', $page);

            $list  = D('BookPostView')->where(array('status'=>1))->limit($Page->firstRow . ',' . $Page->listRows)->order('id desc')->select();

        }

        $bookpost = M('book')->where(array('cate_type'=>1))->select();

        $this->bookposts = list_to_tree($bookpost);

                  $this->assign('list',$list);

                  $this->assign('cateInfo',$cateInfo);

                  $this->assign('catelevel',count($cateInfo));

                  $this->assign('title',$cateInfo['current']['typename']);

                  $this->display();

      }

//模板文件

"{)}" method="post">

             "hidden" name="switchs" value="1"/>

        {:W('Book/cateChoose',array('wid'=>'takebook'))}

             "submit" class="btn submit-btn " value="筛选"/>
