I am trying to create a child theme and need to replace some files that are in sub-folders.
In this post, it states
'get_stylesheet_directory();will go to the current theme, child or parent
Why don’t theme developers just use get_stylesheet_directory() if it would work for the parent or child theme?
It seems that I now have to change every reference to get_template_directory() to get my child files to work (that are in sub-folders) or is there another way of doing this?
This post by Andrew Nacin states that,
you can just replace files directly in a child theme.
But it seems that this only works for one level deep.
Is there a way for this to work with more than one level and would this be easier than changing each reference to get_template_directory()?
The answer is not complicated: “Because you may not want it to work for either the parent or a child theme.”
You choose the function that fits the situation. For example, you have a set of files in the parent theme that contain critical classes or functions. You use
get_template_directory()because you don’t want to allow the child to override/replace the files. It is the same reason you can’t replace WordPress Core files or functions (in most cases).
