upload file in Yii not showing image name/path - php

Question

im here again with a new problem. I am trying to upload a file using yii upload function.
Everything saves well, exept for the image. Here's my code:
Controller:
public function actionUpdate($id)
{
$model=$this->loadModel($id);
$dir = Yii::getPathOfAlias('webroot.images.producten');
// Uncomment the following line if AJAX validation is needed
// $this->performAjaxValidation($model);
if(isset($_POST['Producten']))
{
$model->attributes=$_POST['Producten'];
$model->images=CUploadedFile::getInstance($model,'images');
$nf = $model->images;
if($model->save()){
$this->redirect(array('view','id'=>$model->id));
$model->images->saveAs($dir.'/'.$nf);
$model->images = $nf;
$model->save();
}
}
$this->render('update',array(
'model'=>$model,
));
}
Form:
<div class="row">
<?php echo $form->labelEx($model,'images'); ?>
<?php echo CHtml::activeFileField($model,'images'); ?>
<?php echo $form->error($model,'images'); ?>
</div>
Model:
public function rules()
{
// NOTE: you should only define rules for those attributes that
// will receive user inputs.
return array(
array('naam, beschrijving, prijs', 'required'),
array('images,', 'file', 'allowEmpty'=>true,
'safe' => true,
'types'=> 'jpg, jpeg, png, gif',
'maxSize' => (1024 * 300), // 300 Kb
),
array('aangepast_door', 'numerical', 'integerOnly'=>true),
array('naam', 'length', 'max'=>50),
array('prijs, actieprijs', 'length', 'max'=>10),
//array('toegevoegd, aangepast', 'safe'),
// The following rule is used by search().
// #todo Please remove those attributes that should not be searched.
array('naam, beschrijving, prijs, actieprijs', 'safe', 'on'=>'search'),
);
}
Please help me get this to work.

First of all add enctype= "multipart/form-data" to your form tag or add "enctype" option to associative array if you used form widget yo begin form.
If it will not helps you, please post var_dump($_POST) results here
