Validation Multiuploading?

Hello!

I try create files uploading.

the problem is that I cant pass validation when I use getInstance[color="#FF0000"]s[/color]

this is my controller




public function actionIndex()

	{

		$model = new ImageUpload();

		$dataProvider=new CActiveDataProvider('BannerModel');


		if(isset($_POST['upload']))

		{

			$dir = Yii::getPathOfAlias('webroot').'/images/banners/';


			$model->attributes = $_POST['upload'];

			

			$files = CUploadedFile::getInstances($model, 'file');

			// if($model->validate())

			// {

				foreach($files as $file)

                {

					if(file_exists(Yii::app()->request->getBaseUrl(true).'/images/banners/'.$file->getName()))

					{

						Yii::app()->user->setFlash('error', "Error!");

						$this->render('index',array('dataProvider'=>$dataProvider,'model'=>$model));

						exit();

					}

					else

					{

						$sql = "INSERT INTO banner (`id`, `imgsrc`, `status`) VALUES (NULL, '".$file->getName()."', '1')";

						Yii::app()->db->createCommand($sql)->execute();

						

						$file->saveAs($dir.'/'.$file->getName());

						Yii::app()->user->setFlash('success', "OK!");

						$this->render('index',array('dataProvider'=>$dataProvider,'model'=>$model));

					}

				}

				

		}

		else

		{

			$this->render('index',array('dataProvider'=>$dataProvider,'model'=>$model));

		}

		

	}



and this is my model




class ImageUpload extends CFormModel

{

    public $file;

 

    public function rules()

	{

        return array(

            array('file', 'file', 'types'=>'jpg, jpeg, png', 'maxSize' => 10485760), // 10 mb

        );

    }

}
