Yii2实现增删改查后留在当前页的方法详解

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，如有更好的实现增删改查的方法，欢迎交流。

封装代码

共有两个文件ActionColumn.php和Helper.php

1、ActionColumn.php文件

  [
  'url' => 'view',
  'icon' => 'eye',
  'class' => 'btn btn-success btn-xs',
  'label' => Yii::t('yii', 'View'),
  'appendReturnUrl' => false,
  'url_append' => '',
  'keyParam' => 'id',//是否传id,不传设置null

  [
  'url' => 'update',
  'icon' => 'pencil',
  'class' => 'btn btn-primary btn-xs',
