Yii dropDownList — где сделать логику для выбранного элемента

Я пытаюсь захватить значение, выбранное из dropDownList из CActiveForm, а затем выполнить некоторую логику после отправки …, чтобы затем выполнить запрос. Основываясь на этом запросе, я бы обновил сетку. Эта форма не имеет никаких атрибутов в таблице, которые относятся к ней, но, тем более, я могу создать фильтр для своего GridView после некоторой логики.

Где бы я выполнил эту логику? Я новичок в php, yii и javascript, поэтому я хотел бы, по крайней мере, указать мне правильное направление. Я пытался просмотреть документацию и книги yii, но не нашел то, что мне нужно. я думаю, что я пропускаю что-то критическое из php и web dev, чтобы застрять на чем-то таком тривиальном, как выпадающий список.

Это мой взгляд на admin.php, который затем вызывает метод advanced_search.php с помощью renderPartial.

    <?php
/* @var $this UserController */
/* @var $model User */

$this->breadcrumbs=array(
'Manage Users',
);

/*$this->menu=array(
array('label'=>'List User', 'url'=>array('index')),
array('label'=>'Create User', 'url'=>array('create')),
);
*/
Yii::app()->clientScript->registerScript('search', "$('.asearch-button').click(function(){
$('.asearch-form').toggle();
$('.bsearch-form').toggle();
return false;
});

$('.bsearch-button').click(function(){
$('.bsearch-form').toggle();
$('.asearch-form').toggle();
return false;
});

$('.bsearch-form form').submit(function(){
$('#user-grid').yiiGridView('update', {
data: $(this).serialize()
});
return false;
});

$('.asearch-form form').submit(function(){
$('#user-grid').yiiGridView('update', {
data: $(this).serialize()
});
return false;
});
");
?>

<h2>Manage Users</h2>

<?php echo CHtml::link('Basic Search','#',array('class'=>'bsearch-button')); ?>
<br/>

<!-- basic search-form -->
<div class="bsearch-form" style="display:">
<?php $this->renderPartial('search',array('model'=>$model)); ?>

?>

<?php echo CHtml::submitButton('Search', array("class" => "btn btn-primary")); ?>

<?php $this->endWidget(); ?>
<!-- search-form -->
</div>

мой UserController.php

public function actionAdmin()
{

echo("<script>console.log('actionAdmin');</script>");$model=new User('search');
$model->unsetAttributes();  // clear any default values
if(isset($_GET['User'])){
$model->attributes=$_GET['User'];
