Yii学习(6)----CLinkPager分页

这里我们采用物件的形式来定义分页:

在components中自定义LinkPager，并继承CLinkPager

<?php/** * CLinkPager class file. * * @author Qiang Xue <[e-mail]> * @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. * * @author Qiang Xue <[e-mail]> * @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,$currentPage<=0,false);// prev pageif(($page=$currentPage-1)<0)$page=0;$buttons[]=$this->createPageButton($this->prevPageLabel,$page,self::CSS_PREVIOUS_PAGE,$currentPage<=0,false);// internal pagesfor($i=$beginPage;$i<=$endPage;++$i)$buttons[]=$this->createPageButton($i+1,$i,self::CSS_INTERNAL_PAGE,false,$i==$currentPage);// next pageif(($page=$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,)); ?>

效果如图所示:
