I'm creating a site that lists resources that are referenced in a book. These resources are categorized by book chapter (category), theme (tag), timeline (tag), and also have page numbers (custom meta-box info).
I need the posts to be displayed according to their page number whether we're looking at them by category or tag. I could MANUALLY order them by date -- but there's A LOT of posts.
I've tried looking into get_template_part() and get_post() and can't find ways to override that in functions.php to list alphabetically.
Any help would be appreciated!
