YII框架学习 第五天(1） widget model 修改数据 删除数据

        public function actionUpdate($id)
        {
            $goods_model = Goods::model();
            $goods_info = $goods_model->findByPk($id);
            if(isset($_POST['Goods']))
            {
                foreach($_POST['Goods'] as $k => $v)
                {
                    $goods_info->$k = $v;
                }
                //$goods_info->goods_create_time = time();
                if($goods_info->save())
                {
                    $this->redirect('index.php?r=background/goods/show');
                }
            }
            $this->renderPartial('update',array('goods_model'=>$goods_info));        
        }

代码看着和昨天差不多,添加数据 也用的save方法

add  ----->    $goods_model = new Goods;

update -------> $goods_model = Goods::model();

删除数据

        public function actionDel($id)
        {
            $goods_model = Goods::model();
            $goods_info = $goods_model->findByPk($id); // 一看就知道
            if($goods_info->delete())
            {
                $this->redirect('index.php?r=background/goods/show');                
            }
            var_dump($goods_info);
        }
