问题
i am yiibie and i am trying to use the uploadaction() function in the createaction() function so that i can upload videos and can also manage videos. I am using multiuploadfile extension. I dont know how to merge the upload function into create function.
This is the code of my VideoController which has both the actionUpload() and actioncreate() function.
<?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'.
*/
public $layout='//layouts/admin';
/**
* @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()
{
return array(
array('allow', // allow all users to perform 'index' and 'view' actions
'actions'=>array('index','view'),
'users'=>array('*'),
),
array('allow', // allow authenticated user to perform 'create' and 'update' actions
'actions'=>array('create','update'),
'users'=>array('@'),
),
array('allow', // allow admin user to perform 'admin' and 'delete' actions
'actions'=>array('admin','delete'),
'users'=>array('admin'),
),
array('deny', // deny all users
'users'=>array('*'),
),
);
}
/**
* Displays a particular model.
* @param integer $id the ID of the model to be displayed
*/
public function actionView($id)
{
$this->render('view',array(
'model'=>$this->loadModel($id),
));
}
/**
* Creates a new model.
* If creation is successful, the browser will be redirected to the 'view' page.
*/
public function actionCreate()
{
$model=new Video;
// Uncomment the following line if AJAX validation is needed

if($model->save())
$this->redirect(array('view','id'=>$model->id));
}
$this->render('create',array(

));
}
/**

if(!isset($_GET['ajax']))

}
else
throw new CHttpException(400,'Invalid request. Please do not repeat this request again.');
}

Please help me with this, thank you.

You can call actionUpload() in actionCreate() using $this but you have to check how you will use the actionUpload results depending on what you want:
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 ,
));
}
