您好我是Yii的新手,我想要做的是我有酒店及其物品,我想要显示最高评价。所以在siteController我得到的数据非常好。但是我尝试获取多个数据提供者并渲染index页面,但它无法识别已更改的数据提供者名称。

for ex

public function actionIndex()
    {
        // renders the view file 'protected/views/site/index.php'
        // using the default layout 'protected/views/layouts/main.php'

            $dataProviderHotel=new CActiveDataProvider('Hotel',array(
                'criteria'=>array(
                    'condition'=>'hotel_rating > 8',
                    ),
                    'pagination'=>array(
                        'pageSize'=>20,
                    ),
                ));

            $dataProviderItems = new CActiveDataProvider('Item',array(
                'criteria'=>array(
                    'condition'=>'hotel_rating > 8',
                    ),
                    'pagination'=>array(
                        'pageSize'=>20,
                    ),
                ));



            $this->render('index',array(
            'dataProvider'=>array($dataProviderHotel,$dataProviderItem),
        ));            
    }

并且在视图中抛出异常,即dataProviderHotel未定义 查看代码是

<?php $this->widget('zii.widgets.CListView', array(
        'dataProvider'=>$dataProviderHotel,
        'summaryText'=>'',
        'itemView'=>'_topHotels',
)); ?>

1 个答案:

答案 0 :(得分:4)

应该如下:

$this->render('index',array(
        'dataProvider1'=>$dataProviderHotel,
        'dataProvider2'=>$dataProviderItem
    ));

然后在你看来:

 <?php $this->widget('zii.widgets.CListView', array(
    'dataProvider'=>$dataProvider1,
    'summaryText'=>'',
    'itemView'=>'_topHotels',
 )); 
 ?>
