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。
