Question

我是yiibie，我正在尝试使用uploadaction()功能中的createaction()功能，以便我可以上传视频，还可以管理视频。我正在使用multiuploadfile扩展名。我不知道如何将上传功能合并到创建功能。这是我的VideoController的代码，它同时具有actionUpload()和actioncreate()功能。

<?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(
//          'accessControl', // perform access control for CRUD operations
//          'postOnly + delete', // we only allow deletion via POST request
                    'rights',
        );
    }

请帮帮我，谢谢。

您可以使用actionUpload()在actionCreate()中致电$this但是您必须根据自己的需要检查如何使用actionUpload结果：

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 ,
    ));
}
