Creating dropdown list from related table - yii

Question

I have a two tables:
tbl_day:id_day,mon,tues,wed,thurs,fri,sat,sun
tbl_shft:shft_id,start,end,name,status
I want to have a dropdown table in tbl_day where mon is dependent in the tbl_shft name.
I come up with a dropdown that is displaying data from shift. what I did is.
<?php echo $form->labelEx($model,'sun'); ?>
<?php echo CHtml::activeDropDownList($model,'sun',$model -> getCategories(),array('prompt'=>'Select a Shift'))
?>
and for my model
public function getCategories(){
//this function returns the list of categories to use in a dropdown
return CHtml::listData(Shift::model()->findAll(), 'shft_id', 'name');}
My problem is that it is not submitting. I dont know where my problem here is. Im a beginner in Yii. Hope someone helps. Thanks in advance.

In here your code will work. I think the submitted output was not handled correctly. #sam dark says correctly. Edit your question .just place the controller action of your process . Else you just place this code on your controller action. And give the result of controller on this question itself.
Public function actionYouraction(){
......
if(isset($_POST))
{
echo "<pre>";
print_r($_POST);
exit(); } }
