Yii $this->redirect 跳转失败，也不报错 [ 未指定版本 ]

  if (isset($_POST['Goods'])) {
   foreach ($_POST['Goods'] as $key => $value) {
    $goods_model->$key = $value;
   }
   $goods_model->goods_create_time = time();

    if ($goods_model->save()) {
     $this->redirect('./index.php?r=houtai/goods/show');
    }
  }
$goods_model->save()执行成功，$this->redirect就是不跳转
