Yii cant validate file input - php

Question

I'm currently doing a project in PHP Yii Framework. I have a form which requires the user to upload a file. During the registration, user uploaded the file, however, when user submits the form, the form is always detected blank on the file input, it's like as if there is no attachment on the form. below is the code:
Model - CandidateResume:
return array(
array('resume_file','file','types'=>'doc,docx,pdf', 'allowEmpty'=>true, 'safe'=>true, 'on'=>'register'),
);
Model - Candidate:
return array(
array('can_email,name,repeat_can_email, can_password,repeat_can_password','required', 'on'=>'simplereg'),
);
View:
$form = $this->beginWidget('bootstrap.widgets.TbActiveForm',array(
'id'=>'candidate-form',
'enableAjaxValidation'=>true,
'type'=>'horizontal',
'htmlOptions' => array(
'enctype' => 'multipart/form-data',
'autocomplete'=>'off', //turn off auto complete in FF
)
));
echo $form->textFieldRow($model,'can_email',array('class'=>'span5','maxlength'=>100));
echo $form->textFieldRow($model,'repeat_can_email',array('class'=>'span5','maxlength'=>100));
echo $form->passwordFieldRow($model,'can_password',array('class'=>'span5','maxlength'=>100));
echo $form->passwordFieldRow($model,'repeat_can_password',array('class'=>'span5','maxlength'=>100));
echo $form->fileFieldRow($resume,'resume_file', array('id'=>'resume_file'));
$this->endWidget();
Controller - Candidate:
public function actionCreate()
{
$model = new Candidate();
$model->setScenario('simplereg');
$resume = new CandidateResume();
$resume->setScenario('register');
// Uncomment the following line if AJAX validation is needed
//$this->performAjaxValidation($model);
if(isset($_POST['Candidate'], $_POST['CandidateResume']))
{
$_POST['CandidateResume']['resume_file'] = $resume->resume_file;
$model->attributes = $_POST['Candidate'];
$resume->attributes = $_POST['CandidateResume'];
$uploadedFile = CUploadedFile::getInstance($resume,'resume_file');
if($resume->validate() && $model->validate())
{
$model->save();
if(!empty($uploadedFile)) // check if uploaded file is set or not
{
$saved = $uploadedFile->saveAs(Yii::app()->params['RESUME_PATH'].$model->can_id.'_'.$uploadedFile->getName());
$resume->resume_file = Yii::app()->params['RESUME_DIR'].$model->can_id.'_'.$uploadedFile->getName();
$resume->resume_send_ip = Yii::app()->request->userHostAddress;
}
$resume->save();
}
}
$this->render('create',array('model'=>$model, 'resume'=>$resume));
}
If I remove the validation on the controller:
if($resume->validate() && $model->validate())
The form data can be saved and attachment is placed properly in the folder. However, I need to do the validation for the form. Therefore I cant skip this part.
Is there anything that I missed out? I have checked many times and do researches for the solutions. All provides the similar solutions, therefore I can't figure out the things. Can anyone help me? Thank you in advance.

You don't set the resume_file attribute. It cames from $_FILES not from $_POST
$resume->attributes = $_POST['CandidateResume'];
$uploadedFile = CUploadedFile::getInstance($resume,'resume_file');
$resume->resume_file = $uploadedFile; //add this line
