Yii, already define index but `Undefined Index` - post

Question

I have already properly defined the index to be POST-ed but still it says Undefined Index
Below is my code:
in the _form.php:
<?php echo $form->labelEx($model,'clientPackagedService_id'); ?>
<?php $client = Client::model()->findByPk(1);?>
<?php echo $form->dropDownList($model, 'clientPackagedService_id', CHtml::listData($client->clientPackagedservices(array('condition'=>'client_id='.$client->id.' AND booking_id IS NULL')),'id','packagedServiceInfo'),
array(
'disabled'=>'disabled',
'prompt'=>'Select Packaged Service...',
'ajax' => array( 'type'=>'POST', //request type
'url'=>CController::createUrl('updateMasseuseAndStationListPSID'), //url to call.
//This line-> 'data'=>array('clientPackagedService_id'=>'js:this.value', 'dt'=>'js:$("#Booking_date").val()', 'timeStart'=>'js:$("#Booking_timeStart").val()'),
'dataType'=>'json',
'success'=>'js:function(data) {
//alert(data.masseuse);
var mass="#'.CHtml::activeId($model, 'masseuse_id').'";
$(mass).html(data.masseuse);
$(mass).trigger("chosen:updated");
$(mass+"_chzn").css("width","300px");
$(mass+"_chzn > .chzn-drop").css("width","298px");
var station="#'.CHtml::activeId($model, 'station_id').'";
$(station).html(data.station);
$(station).trigger("chosen:updated");
$(station+"_chzn").css("width","300px");
$(station+"_chzn > .chzn-drop").css("width","298px");
//alert(data.timeEnd);
var timeEnd="#'.CHtml::activeId($model, 'timeEnd').'";
$(timeEnd).val(data.timeEnd);
}',
)
)
); ?>
in the controller.php:
public function actionUpdateMasseuseAndStationListPSID(){
$sid = Booking::getServices($_POST['clientPackagedService_id']);
....(codes to update Masseuse, Station, and TimeEnd.
}
in the model.php
public static function getServices($cpsID){
$psID = Yii::app()->db->createCommand('SELECT packagedService_id FROM client_packagedservice WHERE id='.$cpsID)->queryAll();
$sID = Yii::app()->db->createCommand('SELECT service_id FROM packaged_service WHERE id = '.$psID)->queryAll();
return $sID;
}
As you can see, I have already posted the appropriate name $_POST['clientPackagedService_id'] in the controller.php, but I still get the Error 500: Undefined index: clientPackagedService_id.
Did I do something wrong somewhere? Please advise. Thanks

I think problem is the data your are posting with ajax request. This is your data:
'data'=>array('clientPackagedService_id'=>'js:this.value', 'dt'=>'js:$("#Booking_date").val()', 'timeStart'=>'js:$("#Booking_timeStart").val()'),
Try to change it into this:
'data'=>array('clientPackagedService_id'=>'js:$(this).value', 'dt'=>'js:$("#Booking_date").val()', 'timeStart'=>'js:$("#Booking_timeStart").val()'),
Best way for debugging ajax request is to inspect browser's console. You can see ajax's posted data and realize your problem.
