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 (C) 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,));
     ?>
