Yii分页用法实例详解

下面我总结了在Yii常用的一些yii分页方式与实例代码，这里有普通分页与ajax实现分页，希望此文章对大家会有所帮助。

第一种：CListView分页  针对对象形式的数据分页

Controller:

public function actionAjax() { 

        $criteria = new CDbCriteria(); 

        //$criteria->order = 'news_id DESC'; 

        $criteria->condition = 'user_id = 1'; 

  

        $dataProvider = new CActiveDataProvider('News', array( 

                    'pagination' => array( 

                        'pageSize' => Yii::app()->params['pagesize'], 

                        'pageVar' => Yii::app()->params['pagevar'], 

                    ), 

                    'criteria' => $criteria, 

                )); 

  

  

        $this->render('view', array( 

            'dataProvider' => $dataProvider, 

        )); 

}

View:

<?php 

$this->widget('zii.widgets.CListView', array( 

    'dataProvider' => $dataProvider, //数据 

    'itemView' => '_view', //显示的模版 

    'id' => Yii::app()->controller->id, 

    'itemsTagName' => 'ul', 

    'ajaxVar' => '', //默认为page或ajax 去掉后url更简洁 

    'htmlOptions' => array('class' => Yii::app()->controller->id), 

    'loadingCssClass' => 'loading', //默认为list-view-loading 

    //'template' => '{summary}{sorter}{items}{pager}',//显示的顺序 

    //'ajaxUpdate' => false, //是否ajax分页  false或分页显示的容器id 

    //'beforeAjaxUpdate' => 'before_ajax_update',   //回调函数 在common.js里完成 

    //'afterAjaxUpdate' => 'after_ajax_update',   

    'emptyText' => ' 

<DIV class="alert alert-waning"> 

    暂无数据！ 

</DIV> 

', //无数据时显示内容 

                    'pagerCssClass' => 'pagination', //分页的class 

                    'pager' => array( 

                        'selectedPageCssClass' => 'active', //当前页的class 

                        'hiddenPageCssClass' => 'disabled', //禁用页的class 

                        'header' => '', //分页前显示的内容 

                        'maxButtonCount' => 10, //显示分页数量 

                        'htmlOptions' => array('class' => ''), 

                        'firstPageLabel' => '首页', 

                        'nextPageLabel' => '下一页', 

                        'prevPageLabel' => '上一页', 

                        'lastPageLabel' => '末页', 

                    ), 

                )); 

?>

第二种：CLinkPager  针对数组形式的数据分页

Controller:

public function actionIndex() { 

  

        $criteria = new CDbCriteria(); 

        $criteria->order = 'news_id DESC'; 

        $criteria->condition = 'user_id = 1'; 

  

        $count = News::model()->count($criteria); 

        $pages = new CPagination($count); 

  

        $pages->pageSize = 10; 

        $pages->applyLimit($criteria); 

        $list = News::model()->findAll($criteria); 

  

        $this->render('index', array('list' => $list, 'pages' => $pages)); 

}

View:

<UL> 

    <?php foreach ($list as $item): ?> 

    <LI> 

          

        <DIV class=page-header> 

            <?php echo $item--->news_title; ?> 

        </DIV> 

  

        <DIV class=content> 

            <?php echo $item--->news_intro; ?> 

        </DIV> 

  

    </LI> 

<?php endforeach; ?> 

</UL> 

  

<DIV class=pagination> 

    <?php 

    $this--->widget('CLinkPager', array( 

        'pages' => $pages, 

        'selectedPageCssClass' => 'active', //当前页的class 

        'hiddenPageCssClass' => 'disabled', //禁用页的class 

        'header' => '', //分页前显示的内容 

        'maxButtonCount' => 10, //显示分页数量 

        'htmlOptions' => array('class' => ''), 

        'firstPageLabel' => '首页', 

        'nextPageLabel' => '下一页', 

        'prevPageLabel' => '上一页', 

        'lastPageLabel' => '末页', 

            ) 

    ); 

    ?> 

</DIV>

第三种： DAO实现分页.

Controller层:

public function actionReport()

{

$sql = "select remitdate, sum(rate) sumrate from td_delivery 

group by remitdate 

order by remitdate desc";

$criteria=new CDbCriteria();

$result = Yii::app()->db->createCommand($sql)->query();

$pages=new CPagination($result->rowCount);

$pages->pageSize=2; 

$pages->applyLimit($criteria); 

$result=Yii::app()->db->createCommand($sql." LIMIT :offset,:limit"); 

$result->bindValue(':offset', $pages->currentPage*$pages->pageSize); 

$result->bindValue(':limit', $pages->pageSize); 

$posts=$result->query();

$this->render('report',array( 

'posts'=>$posts, 

'pages'=>$pages, 

));

}

View层:

<?php foreach($posts as $row):?> 

 <?php echo CHtml::link($row["remitdate"],array('delivery/view','remitdate'=>$row["sumrate"]));?>

 <?php echo $row["sumrate"]."<br />" ?>

 <?php endforeach;?>

 <?php 

 //分页widget代码: 

 $this->widget('CLinkPager',array('pages'=>$pages));

?>

优点: DAO效率高; 缺点: view层需要自己写一些样式,稍显麻烦一点

第四种：widget实现分页

model层:

/**

* @var string attribute : 日运费 (统计用)

* 需要对新增加的字段做个声明

*/

public $dayrate;
/*

* 统计功能: 统计每日的运费

*/

public function statistics()

{

$criteria = new CDbCriteria;

$criteria->select = 'remitdate, sum(rate) AS dayrate';

$criteria->group = 'remitdate';

return new CActiveDataProvider(get_class($this), array(

'criteria'=>$criteria,

'sort'=>array(

// 表头设置点击排序的字段

'attributes'=>array(

'remitdate',

'dayrate'=>array(

'asc'=>'dayrate',

'desc'=>'dayrate DESC',

)

),

'defaultOrder'=>'remitdate desc',

),

)); 

}

Controller层:

/**

* 运单统计功能:

* 按日期统计

*/

public function actionReport()

{

$model=new Delivery('statistics');

$model->unsetAttributes(); // clear any default values

  

$this->render('report',array(

'model'=>$model,

));

}

View层:

<?php $this->widget('zii.widgets.grid.CGridView', array(

'id'=>'delivery-grid',

'dataProvider'=>$model->statistics(),

'filter'=>$model,

'columns'=>array(

'remitdate',

'dayrate',

array(

'class'=>'CButtonColumn',

),

),

));

?>

优点: 可以使用自带的样式; 缺点: 效率略低.

第五种：Ajax分页

YII中ajax分页有多种实现方法，比较传统的就是在view中写JS来实现，大概的就是这样:
在view中js大概逻辑是这样

$('#listview .yiiPager a').live('click',function(){

        $.ajax({

            url:$(this).attr('href'),

            success:function(html){

                $('#listview').html(html);

            }

        });

        return false;//阻止a标签

});

然后在controller中判断ajax请求，再使用renderPartial方法渲染局部List视图，然后局部视图会被view中的ajax方法填充到局部刷新的div中。controller的大概逻辑是:

if (Yii::app()->request->isAjaxRequest) {

$this->renderPartial('_comments',array(

    'model' => $model,

    'comments' => $comments,//在局部视图中foreach得到每条数据

    'pages' => $pages,

   ));

    Yii::app()->end();

}

后来发现YII中的CListview更方便，封装了分页，foreach显示list，还支持数据排序。具体的可以在YII的API手册中发掘。使用CListview是默认ajax分页的，使用方法如下：

controller中：

$criteria = new CDbCriteria();

$criteria->order = '`create_time` DESC';

$dataProvider = new CActiveDataProvider('Comments', array(

    'pagination'=>array(

      'pageSize'=>Yii::app()->params['commentsPerPage'],//设置分页条数以确定取出数据的条数

  ),

  'criteria'=>$criteria,

  ));

$this->render('comments',array(

         'model' => $model,

         'dataProvider' => $dataProvider,

));

然后在view中：

<?php $this->widget('zii.widgets.CListView', array(

  'dataProvider'=>$dataProvider,

  'itemView'=>'_comments',

  //'ajaxUpdate'=> false,//这样就不会AJAX翻页

  'pager' => array(//pager 的配置信息。默认为<CODE>array('class'=>'CLinkPager')</CODE>.也可以自己配置

   'nextPageLabel' => '下一页 »',

   'prevPageLabel' => '« 上一页'

  ),

//在这里还可以配置一些排序规则，具体可以查阅手册

));

?>

这样就实现了Ajax分页，很方便。

希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
