在带有CGridView的Yii Framework中，我需要从CActiveRecord中读取一个值
CGridView中的列定义适用于列：
'columns'=>array(
....
array(
'name'=>'rel_CustomerCampain.event_comment',
'header'=>'Commenti Camp.',
'value'=>'print_r($data->rel_CustomerCampain,false)'
),
.....
我有这个对象$ data-＆gt; rel_CustomerCampain，我需要在“_attributes：CActiveRecord：private”下的event_comment中获取值： 的 * IneedOfThisValue 的 **
当我尝试 '值'=＆GT; '$ DATA-＆GT; rel_CustomerCampain-＆GT; event_comment'
我有这个错误： “试图获取非对象的属性”
谁有想法？ 提前谢谢....[0] => customerCampain Object

答案 0 :(得分：1)
由于我怀疑 1 ，您当前的模型（即您正在显示gridview的模型）与 CustomerCampain 模型之间存在HAS_MANY关系。这意味着$data->rel_CustomerCampain是 CustomerCampain 对象的数组，也可以从print_r输出中看到：
[0] => customerCampain Object
(
...
)
所以而不是：
'value'=>'$data->rel_CustomerCampain->event_comment'
你必须这样做：
'value'=>'$data->rel_CustomerCampain[arrayIndex]->event_comment'
// here arrayIndex will have to be the index of the campain you are interested in
'value'=>'$data->rel_CustomerCampain[0]->event_comment' // 0 index for the first campain
