我希望有人能给我指出正确的方向。

我正在使用Wordpress插件样板来开发一个自定义插件。安装时，插件将注册新的帖子类型（课程）、新的分类法（课程区域），并为新的帖子类型和分类法设置永久链接结构。

我已将代码（用于创建帖子类型和分类）添加到Activator类中，如下所示，但代码似乎没有运行，我希望guess 这是由我使用的add\\u操作挂钩（即codex为插件安装推荐的“init”挂钩）引起的，因为如果我在主插件文件（iwcollege-courses.php）中调用它，代码将按预期运行，但我真的不确定。

值得注意的是，我在激活插件时没有收到任何错误，它似乎激活成功，but no custom post types or taxonomies are created.

关于为什么会发生这种情况，以及我如何补救这种情况，有什么想法吗？

提前感谢，
