Yii: cómo usar actionupload() en actioncreate()

Question

Soy yiibie y estoy tratando de usar la función uploadaction() en la función createaction() para poder subir videos y también administrar videos. Estoy usando la extensión de multiuploadfile . No sé cómo combinar la función de carga en la función de creación. Este es el código de mi VideoController que tiene las actionUpload() y actioncreate() .

<?php

class VideoController extends RController
{
    /**
    * @var string the default layout for the views. Defaults to ''//layouts/column2'', meaning
    * using two-column layout. See ''protected/views/layouts/column2.php''.

    /**
    * @return array action filters
    */
    public function filters()
    {
        return array(
//          ''accessControl'', // perform access control for CRUD operations
//          ''postOnly + delete'', // we only allow deletion via POST request
                    ''rights'',
        );
    }

    /**
    * Specifies the access control rules.
    * This method is used by the ''accessControl'' filter.
    * @return array access control rules
    */
    public function accessRules()
    {

            array(''allow'',  // allow all users to perform ''index'' and ''view'' actions
                ''actions''=>array(''index'',''view''),

Por favor, ayúdenme con esto, gracias.

Puede llamar a actionUpload() en actionCreate() usando $this pero debe verificar cómo usará los resultados de actionUpload dependiendo de lo que desee:

public function actionCreate() {
    $model = new Video;

    // Uncomment the following line if AJAX validation is needed
    // $this->performAjaxValidation($model);

    if (isset($_POST[''Video''])) {
        $model->attributes = $_POST[''Video''];

        $upload_results = $this->actionUpload();
        //Do something with $upload_results here

        if ($model->save()) {
            //Or after model saving do related saving with $upload_results here
            $this->redirect(array(''view'', ''id''=>$model->id));
        }
    }
    $this->render(''create'', array(
        ''model''=>$model,
        //''upload_results ''=>$upload_results ,
    ));
}
