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); }}
