Oct 11, 2020 at 6:13	comment	added	Sally CJ		Yes, that's fine. And check out the docs for `add_action()` here, but the `10` means the callback's priority - if there were 4 callbacks hooked to `save_post`, that priority determines the position of your own callback, e.g. is it the first or last one that executes. And the `2` is the number of args your callback accepts, but you need to check the hook docs (e.g. this for `save_post`) to know all the args for that specific hook.
