将yii自带的两个分页合二为一 [ 新手入门 ]

1、创建一个类文件CWetPager.php放到framework\web\widgets\pagers\文件下 代码如下：

<?php

/**

			return array();
			
		list($beginPage,$endPage)=$this->getPageRange();
		$currentPage=$this->getCurrentPage(false); // currentPage is calculated in getPageRange()

	}

			$url=CHtml::asset(Yii::getPathOfAlias('system.web.widgets.pagers.pager').'.css');

	}
}

2、在framework文件夹下分别修改YiiBase.php和yiilite.php 的 private static $_coreClasses 这个数组 添加 'CWetPager' => '/web/widgets/pagers/CWetPager.php',

'CLinkPager' => '/web/widgets/pagers/CLinkPager.php',
'CListPager' => '/web/widgets/pagers/CListPager.php',
'CWetPager' => '/web/widgets/pagers/CWetPager.php',

3、在视图页面的分页改为 'pager'=>array('class'=>'CWetPager'),到这一步两个分页就合一了，如果还希望更新页面后返回上一页就在加入以下代码 视图加 'ajaxUpdate'=> false,//取消分页的ajax 控制器里的方法加[code]//返回上一页 Yii::app()->request->urlReferrer; 4、显示首页尾页 修改framework\web\widgets\pagers\pager.css把的代码隐藏就可以了。

ul.yiiPager .first,
ul.yiiPager .last
{
	display:none;
}
