Yii实现分页的两种方法,一种是用DAO实现,另外一种是在widget实现.
各有优点吧,第一种效率会高一点,第二种可以使用自带的表格,方便一些.
一. DAO实现分页.
[Controller层]
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;">
$row["sumrate"]));?>
PHP echo $row["sumrate"]."
" ?> widget('CLinkPager',array('pages'=>$pages)); ?>
" ?> 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
二. widget实现分页
[model层]
/*
- 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]
unsetAttributes(); // clear any default values
$this->render('report',array(
'model'=>$model,));}
[View层]
PHP;">
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.
