WordPress 在后台按文件夹分类主题

问题描述

我想组织主题：

wp-content/themes/themeshop/theme1
wp-content/themes/themeshop/theme2
wp-content/themes/themeshop/theme3

从我的理解，这个组织在文件夹级别上完美的工作。我删除了子目录中的主题，一切似乎都很好。现在可以在主题页面的管理后台复制此分类吗？

最佳解决办法

Updated plugin version available at GitHub.

我第一次在 [wp-hackers] list 看到你的问题，在实施解决方案之后，即将出版一份 Q&A 。嗯，它已经在这里了，并有一个赏金放在它:)

正如 Daniel Bachhuber 指出的那样：

WordPress.com puts themes inside of subdirectories
/wp-content/themes/public  /wp-content/themes/premium 

我想出了这个解决方案，显示在后端：

在「多站点」中，我们可以在「主题」屏幕中添加一列，并使用 manage_themes_custom_column 和 manage_themes-network_columns 显示信息。
在单站安装中，我发现的唯一入口点是 theme_action_links 。

结果在多站点：文件夹/themes/clientes/和/themes/brasofilo/) 。在网络的 sub-sites 中没有输出。
