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:
复制代码 代码如下:
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,
));
}
$criteria = new CDbCriteria();
//$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:
复制代码 代码如下:
<?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',
),
));
?>
$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:
复制代码 代码如下:
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));
}
$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' => $pages));
}
View:
复制代码 代码如下:
<UL>
<?php foreach ($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' => $pages,
'selectedPageCssClass' => 'active', //当前页的class
'hiddenPageCssClass' => 'disabled', //禁用页的class
'header' => '', //分页前显示的内容
'maxButtonCount' => 10, //显示分页数量
'htmlOptions' => array('class' => ''),
'firstPageLabel' => '首页',
'nextPageLabel' => '下一页',
'prevPageLabel' => '上一页',
'lastPageLabel' => '末页',
)
);
?>
</DIV>
<?php foreach ($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:
复制代码 代码如下:
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,
));
}
{
$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'=>$pages,
));
}
View层:
复制代码 代码如下:
<?php foreach($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));
?>
<?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:
复制代码 代码如下:
/**
* @var string attribute : 日运费 (统计用)
* 需要对新增加的字段做个声明
*/
public $dayrate;
* @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:
复制代码 代码如下:
/**
* 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,
));
}
* 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:
复制代码 代码如下:
<?php $this->widget('zii.widgets.grid.CGridView', array(
'id'=>'delivery-grid',
'dataProvider'=>$model->statistics(),
'filter'=>$model,
'columns'=>array(
'remitdate',
'dayrate',
array(
'class'=>'CButtonColumn',
),
),
));
?>
'id'=>'delivery-grid',
'dataProvider'=>$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
复制代码 代码如下:
$('#listview .yiiPager a').live('click',function(){
$.ajax({
url:$(this).attr('href'),
success:function(html){
$('#listview').html(html);
}
});
return false;//阻止a标签
});
$.ajax({
url:$(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:
复制代码 代码如下:
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();
}
$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：
复制代码 代码如下:
$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,
));
$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：
复制代码 代码如下:
<?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
));
?>
'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。
