Yii使用CLinkPager分页实例详解

本文主要讲解了yii中使用clinkpager分页的方法，这里我们采用物件的形式来定义分页:

首先在components中自定义linkpager，并继承clinkpager

具体代码如下：

<?php
/**
 * clinkpager class file.
 *
 * @link http://www.yiiframework.com/
 * @copyright copyright © 2008-2011 yii software llc
 * @license http://www.yiiframework.com/license/
 */

/**
 * clinkpager displays a list of hyperlinks that lead to different pages of target.
 *
 * @version $id$
 * @package system.web.widgets.pagers
 * @since 1.0
 */
class linkpager extends clinkpager
{
 const css_total_page='total_page';
 const css_total_row='total_row';
 
 /**
 * @var string the text label for the first page button. defaults to '<< first'.
 */
 public $totalpagelabel;
 /**
 * @var string the text label for the last page button. defaults to 'last >>'.
 */
 public $totalrowlabel;
 
 /**
 * creates the page buttons.
 * @return array a list of page buttons (in html code).
 */
 protected function createpagebuttons()
 {
 

    $this->maxbuttoncount=8; 
    $this->firstpagelabel="首页";
    $this->lastpagelabel='末页'; 
    $this->nextpagelabel='下一页';
    $this->prevpagelabel='上一页'; 
    $this->header="";
 
 if(($pagecount=$this->getpagecount())<=1)
  return array();
 
 list($beginpage,$endpage)=$this->getpagerange();
 $currentpage=$this->getcurrentpage(false); // currentpage is calculated in getpagerange()
 $buttons=array();
 
 // first page
 $buttons[]=$this->createpagebutton($this->firstpagelabel,0,self::css_first_page,$currentpage<=0,false);

 // prev page
 if(($page=$currentpage-1)<0)
  $page=0;
 $buttons[]=$this->createpagebutton($this->prevpagelabel,$page,self::css_previous_page,$currentpage<=0,false);

 // internal pages
 for($i=$beginpage;$i<=$endpage;++$i)
  $buttons[]=$this->createpagebutton($i+1,$i,self::css_internal_page,false,$i==$currentpage);

 // next page
 if(($page=$currentpage+1)>=$pagecount-1)
  $page=$pagecount-1;
 $buttons[]=$this->createpagebutton($this->nextpagelabel,$page,self::css_next_page,$currentpage>=$pagecount-1,false);

 // last page
 $buttons[]=$this->createpagebutton($this->lastpagelabel,$pagecount-1,self::css_last_page,$currentpage>=$pagecount-1,false);
 
 // 页数统计
 $buttons[]=$this->createtotalbutton(($currentpage+1)."/{$pagecount}",self::css_total_page,false,false);
 
 // 条数统计
 $buttons[]=$this->createtotalbutton("共{$this->getitemcount()}条",self::css_total_row,false,false);

 return $buttons;
 }
 
 protected function createtotalbutton($label,$class,$hidden,$selected)
 {
 if($hidden || $selected)
  $class.=' '.($hidden ? self::css_hidden_page : self::css_selected_page);
 return '<li class="'.$class.'">'.chtml::label($label,false).'</li>';
 }
 
 /**
 * registers the needed client scripts (mainly css file).
 */
 public function registerclientscript()
 {
 if($this->cssfile!==false)
  self::registercssfile($this->cssfile);
 }
 
 /**
 * registers the needed css file.
 * @param string $url the css url. if null, a default css url will be used.
 */
 public static function registercssfile($url=null)
 {
 if($url===null)
  $url=chtml::asset(yii::getpathofalias('application.components.views.linkpager.pager').'.css');
 yii::app()->getclientscript()->registercssfile($url);
 }
}

定义css样式

/**
 * 翻页样式
 */
.page_blue{
 margin: 3px;
 padding: 3px;
 text-align: center;
 font: 12px verdana, arial, helvetica, sans-serif;
}
ul.bluepager,ul.yiipager
{
 font-size:11px;
 border:0;
 margin:0;
 padding:0;
 line-height:100%;
 display:inline;
 text-aligin:center;
}

ul.bluepager li,ul.yiipager li
{
 display:inline;
}

ul.bluepager a:link,ul.yiipager a:link,
ul.bluepager a:visited,ul.yiipager a:visited,
ul.bluepager .total_page label,ul.yiipager .total_page label,
ul.bluepager .total_row label,ul.yiipager .total_row label
{
 border: #ddd 1px solid;
 color: #888888 !important;
 padding:2px 5px;
 text-decoration:none;
}

ul.bluepager .page a,ul.yiipager .page a
{
 font-weight:normal;
}

ul.bluepager a:hover,ul.yiipager a:hover
{
 color:#fff !important; border:#156a9a 1px solid; background-color:#2b78a3
}

ul.bluepager .selected a,ul.yiipager bluepager .selected a
{
 color:#3aa1d0 !important;
 border: 1px solid #3aa1d0;
}

ul.bluepager .selected a:hover,ul.yiipager .selected a:hover
{
 color:#fff !important;
}

ul.bluepager .hidden a,ul.yiipager .hidden a
{
 border:solid 1px #dedede;
 color:#888888;
}

ul.bluepager .hidden,ul.yiipager .hidden
{
 display:none;
}

controller中操作：

//分页操作
$criteria=new cdbcriteria;
$criteria->order='id desc';
$criteria->select=array('id','uid','username','title','thumb','url','clicks','time','dateline','countfavorite','quality');
$criteria->condition=$sql;
$total = video::model()->count($criteria);

$pages = new cpagination($total);  
$pages->pagesize=self::page_size;
$pages->applylimit($criteria);
  
$list = video::model()->findall($criteria);

$title = commonclass::model()->find(array(
 'select'=>array('cname'),
 'condition'=>'id = '.$id,
));  

$this->render('application.views.video.list',array(
 'array'=>$array,
 'arr'=>$arr,
 'result'=>$result,
 'list'=>$list,
 'pages'=>$pages,
 'title'=>$title,
));

在views/video/list.php中引用:

<?php
 $this->widget('linkpager', array('pages' => $pages,));
 ?>
