Yii2 增删改查后仍留在当前页的方法

摘要：序言实现增删改查操作成功后仍留在当前页，能给用户一个良好的体验。殊途同归，如有更好的实现方法，欢迎交流。需求分析实现增删改查后操作成功后仍然留在当前页面。分析总结此方法的好处是不动核心代码，调用方式保留了自带的方式。

实现增删改查操作成功后仍留在当前页，能给用户一个良好的体验。但是 Yii2 框架本身是没有在增删改查操作成功后仍留在当前页的效果的，要实现这样的一个效果得自己写。我的原则是不动核心代码，始终坚持自己的原则，现实现了我把它分享出来。殊途同归，如有更好的实现方法，欢迎交流。

1、实现增删改查后操作成功后仍然留在当前页面。

1、链接的效果图

共有两个文件ActionColumn.php和Helper.php
1、ActionColumn.php文件
