Using instructions from the WordPress codex, I have replaced/added to a number of WordPress core and theme functions. For these tasks, code, such as
add_action( 'after_setup_theme', 'mytheme_custom_header_setup'); are already putting the code to work in the right place of the processing.
Now, I have a situation where I want to move code from a custom WordPress template in a child theme into
functions.php and call it from the template file as needed. In this case, essentially, I want to move code into
functions.php that will include a few layers into a highly customized
front-page.php after pulling in some custom field data.
Do child theme template files have access to
functions.php or do I need to add some code somewhere to make that connection?
