各有優(yōu)點(diǎn)吧,第一種效率會(huì )高一點(diǎn), 第二種可以使用自帶的表格,方便一些.
一. DAO實(shí)現分頁(yè).
[Controller層]
1 public function actionReport()
2 {
3 $sql = "select remitdate, sum(rate) sumrate from td_delivery
4 group by remitdate
5 order by remitdate desc";
6 $criteria=new CDbCriteria();
7 $result = Yii::app()->db->createCommand($sql)->query();
8 $pages=new CPagination($result->rowCount);
9 $pages->pageSize=2;
10 $pages->applyLimit($criteria);
11 $result=Yii::app()->db->createCommand($sql." LIMIT :offset,:limit");
12 $result->bindValue(':offset', $pages->currentPage*$pages->pageSize);
13 $result->bindValue(':limit', $pages->pageSize);
14 $posts=$result->query();
15 $this->render('report',array(
16 'posts'=>$posts,
17 'pages'=>$pages,
18 ));
19 }
[View層]
1 <?php foreach($posts as $row):?>
2 <?php echo CHtml::link($row["remitdate"],array('delivery/view','remitdate'=>$row["sumrate"]));?>
3 <?php echo $row["sumrate"]."<br />" ?>
4 <?php endforeach;?>
5 <?php
6 //分頁(yè)widget代碼:
7 $this->widget('CLinkPager',array('pages'=>$pages));
8 ?>
優(yōu)點(diǎn): DAO效率高; 缺點(diǎn): view層需要自己寫(xiě)一些樣式,稍顯麻煩一點(diǎn)
二. widget實(shí)現分頁(yè)
[model層]
1 /**
2 * @var string attribute : 日運費 (統計用)
3 * 需要對新增加的字段做個(gè)聲明
4 */
5 public $dayrate;
6
7
8 /*
9 * 統計功能: 統計每日的運費
10 */
11 public function statistics()
12 {
13 $criteria = new CDbCriteria;
14 $criteria->select = 'remitdate, sum(rate) AS dayrate';
15 $criteria->group = 'remitdate';
16
17 return new CActiveDataProvider(get_class($this), array(
18 'criteria'=>$criteria,
19 'sort'=>array(
20 // 表頭設置點(diǎn)擊排序的字段
21 'attributes'=>array(
22 'remitdate',
23 'dayrate'=>array(
24 'asc'=>'dayrate',
25 'desc'=>'dayrate DESC',
26 )
27 ),
28 'defaultOrder'=>'remitdate desc',
29 ),
30 ));
31 }
[Controller層]
1 /**
2 * 運單統計功能:
3 * 按日期統計
4 */
5 public function actionReport()
6 {
7 $model=new Delivery('statistics');
8 $model->unsetAttributes(); // clear any default values
9
10 $this->render('report',array(
11 'model'=>$model,
12 ));
13 }
[View層]
1 <?php $this->widget('zii.widgets.grid.CGridView', array(
2 'id'=>'delivery-grid',
3 'dataProvider'=>$model->statistics(),
4 'filter'=>$model,
5 'columns'=>array(
6 'remitdate',
7 'dayrate',
8 array(
9 'class'=>'CButtonColumn',
10 ),
11 ),
12 )); ?>
