注册带或不带钩子的侧边栏
Registering sidebar with or without hook
我对此有点困惑。在 Wordpress 的函数文件中注册侧边栏时，我们使用 register_sidebar() 函数并在其中传递参数。
在不使用任何动作钩子的情况下，侧边栏工作得很好。但是，在手抄本中，我看到一个名为 'widget_init' 的动作挂钩用于注册侧边栏。所以，我的困惑是注册侧边栏的标准方法是什么，有或没有动作挂钩？
我发现 this interesting piece 在注册侧边栏上写着
Bad sidebar code
There are some common things I would like to see changed within
themes. Not all of these things are technically incorrect, but they
can present some unintended consequences or are just needless bits of
code.
Problem #1: Randomly dropping code into functions.php
If you’re a theme developer, you should be familiar with WordPress’
built-in hooks. Not only should you be familiar with them, you should
actually be using them.
The biggest issue I see is sidebar code just being dropped into
functions.php. You should create a sidebar registration function and
hook it to widgets_init. You can see an example of this in the
“Registering a dynamic sidebar” section above.
The reason this is important is so that child themes (and even
plugins) can know exactly when a sidebar was registered. This gives
child themes the opportunity unregister a sidebar if needed. Plus, not
doing it this way is just plain sloppy.
As a sidenote to this: You should never just drop code into
functions.php. Always use the hooks WordPress provides to execute your
functions when they should be executed in the WordPress flow.
