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);
}
