我已经尝试了几个小时来修改这个插件以使用自定义分类而不是帖子标题和/或帖子内容
http://wordpress.org/extend/plugins/kau-boys-autocompleter/
添加了我认为应该进行修改的插件的代码/部分。我可以发布一些我尝试过的东西，但我认为它只会让人们感到困惑，我不认为我曾经接近过。通常我可以完美地修改代码，但似乎找不到它。我已经尝试过这里发布的这种方法。
http://wordpress.org/support/topic/autocomplete-taxonomy-in-stead-of-title-or-content
但它不起作用。我已经尝试围绕他的建议寻找可能的解决方案，但我开始认为他的建议甚至还没有接近修复它。
