wordpress进阶教程(十四):给分类添加字段类文件

敬告：本类文件发表于2013年，可能已经过时，请参考或直接使用Ashuwp_framework框架。

在这篇教程作者将要结束给wordpress分类添加字段的教程，教程最后当然是送出类文件，前面也放出过两个类文件：主题后台、文章自定义字段。

但是这个类文件不一样，该类文件为wp自学笔记原创，所以有不完美的地方，比如没有提供图片上传的，不过如果读者需要，参考一下前面主题后台和文章自定义字段的两个类文件，完全可以自己添加进来。

版本控制：

2013.07.08，版本 1.0

1、增加删除分类删除数据功能

2、增加和更新-编辑器、图片上传、复选框等功能

类文件代码-2013年7月8日更新：
