Yii 1.1 General Discussion

Hi,

I want to use dependent dropdowns in my jappendo. I have written the following code so far which is static and works. I want to make it dynamic.


 		 

 $product = CHtml::listData(Products::model()->findAll(),'product_id','product_name');  

			echo CHtml::DropDownList('product_id[]','',$product,  array(

				'prompt'=>'Select Location...', 

			 'ajax' => array('type'=>'POST',  

		 'url'=>  Yii::app()->createUrl( "PurchaseOrder/units"), 

		 'update'=>'#param_id'

			)));?>                                

                                

                                                               

                               <div id="param_id"  class="row">

		

	

       <?php echo CHtml::DropDownList('unit[]','',array(prompt=>'select')); ?>


		

	</div>

And in my controller:


public function actionUnits()


{ 

$product_id =  $_POST['product_id'][0];// this makes it static. i want to fetch product_id dynamically

            $data=Products::model()->findAll('product_id=:product_id', 

                  array(':product_id'=> $product_id));

 

    $data=CHtml::listData($data,'unit','unit');

    foreach($data as $value=>$name)

    {

        echo CHtml::tag('option',

                   array('value'=>$value),CHtml::encode($name),true);

    }


 

          

		  

    }

Please help.

Thanks
