Zend Framework框架实现类似Google搜索分页效果


            本文实例讲述了Zend Framework框架实现类似Google搜索分页效果。分享给大家供大家参考，具体如下：





/**

*

* @param unknown_type $model 表类型

* @param unknown_type $ncontroller 那个控制器提交的controller

* @param unknown_type $naction 那个action提交的action

*/

public function fenyepage2($model,$ncontroller,$naction){

    if(!isset($_SESSION))

    {session_start();}

    $pageSize = $_SESSION['pagesize'];

    $pageNow = $_SESSION['pagenow'];

    $offset = ($pageNow-1)*$pageSize;

    $db = $this->getAdapter();

    $select = $db->select();

    $select->from('student','*');

    if(!isset($_SESSION))

    {session_start();}

    if($_SESSION['qsname']!=""){

      $sname = $_SESSION['qsname'];

      $select->where('sname like ?',"%$sname%");

    }

    if($_SESSION['qsaddress']!=""){

      $saddress = $_SESSION['qsaddress'];

      $select->where('saddress like ?',"%$saddress%");

    }

    if($_SESSION['qsdept']!=""){

      $sdept = $_SESSION['qsdept'];

      $select->where('sdept like ?',"%$sdept%");

    }

    $coutNews = $db->fetchAll($select);

    $pageCount = ceil(count($coutNews)/$pageSize);

    $select->limit($pageSize,$offset);//第一个参数:总共显示多少个。第二个参数:从第几个开始显示

    $res = $db->fetchAll($select);

    $native = null;

    $native = "<a href='\\$ncontroller\\$naction?pageNow=1&pagesize=$pageSize'>首页</a>&nbsp";

    if($pageNow>1){

      $nextPage = $pageNow-1;

      $native.=" <a href='\\$ncontroller\\$naction?pageNow=$nextPage&pagesize=$pageSize'>上一页</a> ";

    }

      if(($pageNow-1)>5){

        if($pageNow+4>$pageCount){//如果最后的页数和理应前面开始的页数小于10则

          $start = $pageCount-9;//开始的页数和结束的页数相差9

        }else{

          $start=$pageNow-5;//开始位置和结束位置相差5

        }

      }else{

        $start = floor(($pageNow-1)/10)*10+1;

      }

      if($pageCount>=$start+10){

        $index = $start+10;

      }

      else{

        $index = $pageCount+1;

      }

      for(;$start<$index;$start++){

        $native.="  <a href='\\$ncontroller\\$naction?pageNow=$start&pagesize=$pageSize'>$start</a>";

      }

    if($pageNow<$pageCount){

      $nextPage = $pageNow+1;

      $native.="  <a href='\\$ncontroller\\$naction?pageNow=$nextPage&pagesize=$pageSize'>下一页</a> ";

    }

    $native.="  <a href='\\$ncontroller\\$naction?pageNow=$pageCount&pagesize=$pageSize'>末页</a> ";

    $native.="  当前{$pageNow}||总共{$pageCount}页";

    $model->arrs = $res;

    $model->native = $native;

}
