如何从yii中的另一个视图中检索一个视图中变量的值

Question

I have a variable in admin.php .i.e $approved. This is got by the value of a radiobutton using this code.

$approval = Yii::app()->request->getParam('approval',"0");

Now, I need to pass this variable from admin page to update page. For which I have written the following lines

array(
            'class'=>'CButtonColumn',
                        'template'=>'{update}',
                        'buttons' => array(
                    'view' => array (                    
                        'url' => 'Yii::app()->controller->createUrl("/testSettings/update", array("id"=>$data->Id,"approval"->$approval))',
                    ),
                ),

I'm not able to retrieve the value of $approved in _form.php. But, when I gave echo $approved,PHP notice is displayed saying $approved not definedbut actual value of $approval should be 1. What does this mean and how can I solve this.

You can pass that value to _form as shown

$this->renderPartial('_form',array('approval'=>$approval);

You can pass as a value param as shown

'columns'=>array(
      array(
          'name'=>'yorName',
          'value'=>function($data, $row) use ($controller){
                return $controller->renderPartial('_form', array('approved'=>$approved), true);
          }
      )
  ),
