I have this form.


<div class="row">

<?php echo $form->labelEx($model,'type'); ?>

<?php echo $form->dropDownList($model,'type',Type::Group(),

            array(

                'empty'=>'',

                'ajax' => array(

                'type'=>'POST',

                'url'=>CController::createUrl('price'),

                'update'=>'#price .price',

                )

            )); 

 ?>

 <?php echo $form->error($model,'type'); ?>

 </div>

 <div class="row">

     <div id='price'><span>price: </span>

     <span class='price'></span>

     </div> 

 </div>

 <div class="row">

 <?php echo $form->labelEx($model,'my_list'); ?>

 <?php echo $form->dropDownList($model,'my_list',$list); ?>

 <?php echo $form->error($model,'my_list'); ?>

 </div>

and this is my action


<?php

public function actionPrice(){

        if(isset($_POST['Catalog']['type'])){

            $id = $_POST['Catalog']['type'];

            $modelOne = PriceCatalog::model()->findByPk($id);

            $price = $modelOne->price * 2;

            $models = Price::model()->findAllByAttributes(array(),'price_id=:price_id',array(':price_id'=>$priceID));

            $array = array();

            foreach($models as $model){

                $array[$model->id] = $model->title;

            }  

            $list = $array;           

        }

    }

?>

I send to server


$_POST['Catalog']['type']

and then I want send from server $price and $list.

I must use $price in the span


<span class='price'></span>

and use $list for the another drop down list :


<?php echo $form->dropDownList($model,'my_list',$list); ?>

How can do this?
