dropdown list with submit in yii - php

Question

i want to have a drop down list and a submit button, when the button pressed i want to get the text of selected item and store it into db. my drop down code in view is :
<?php
$form=$this->beginWidget('CActiveForm', array(
'enableAjaxValidation'=>true,
'clientOptions'=>array('validateOnSubmit'=>true
),
)); ?>
<?php echo $form->labelEx($model,'actTopic'); ?>
<?php echo $form->error($model,'actTopic'); ?>
<?php
echo CHtml::dropDownList('actTopic', $category,$list,
array('empty' => '... '));
?>
it generates a drop down list fine.
but i don't know how i can get the selected item in my action function.
the action function is:
public function actiongivePoint()
{
$model=new GivePointForm;
if(isset($_POST['GivePointForm'])){
$model->attributes=$_POST['GivePointForm'];
if($model->validate()){
$actTopic=($model->actTopic);
$actPoint=($model->actPoint);
$actId=($model->actId);
$stCode = (int) $_GET['stCode'];
$connection=Yii::app()->db;
$connection->active=TRUE;
$actIdReader =Yii::app()->db->createCommand()
->select ('actID')
->from('refrencepoint')
->where("actTopic=:actTopic")
->queryScalar(array(':actTopic'=>$actTopic));
$search =Yii::app()->db->createCommand()
->select ('count(*)')
->from('point')
->where(array('and', 'actId=:actID', 'stCode=:stCode') )
->queryScalar(array(':actId'=>$actId,':stCode'=>$stCode));
if($search !=0){
$month=CDateFormatter::formatMonth(now());
$year=CDateFormatter::formatMonth(now());
$command =$command->update('point', array(
'year'=>$year,'month'=>$month,
'pcounter'=>new CDbExpression('pcounter + 1'),),
(array('and','actId'=>$actId, 'stCode'=>$stCode))) ;
Yii::app()->user->setFlash('point','....');
}
else{
$month=CDateFormatter::formatMonth(now());
$year=CDateFormatter::formatMonth(now());
$command->insert('point', array('actId'=>$actId,
'stCode'=>$stCode,'year'=>$year,'month'=>$month,
'pcounter'=>new CDbExpression('pcounter + 1')));
Yii::app()->user->setFlash('point','....');
}
}
}
$this->render('givePoint',array('model'=>$model));
}
i should say i don't use active record.
with above codes it looks like everything is ok in view, but when i press submit button nothing happen, no change in db and even no error just the page refresh!!
what is wrong here?
i am so tired of trying....

I think you just use like it.
you first use foreach loop.I am not sure which type of things your are listing. but you need to do work like in below.
It is an example
foreach($model->category as $list) {
$list['id'] = $list->name;
}
echo CHtml::dropDownList($model, 'actTopic', $list);
Now you debug your code.
public function actiongivePoint()
{
$model=new GivePointForm;
if(isset($_POST['GivePointForm'])){
print_r($_POST['GivePointForm']);
exit; //Just check either the form is posted or not and values are coming or not.
$model->attributes=$_POST['GivePointForm'];
if($model->validate()){
$actTopic=($model->actTopic);
echo $actTopic ;
exit ; // Check either your dropdown item id is coming or not.
Hope its help you.
Thanks.
