Our includes are rather chaotic. functions.php has turned into a dumping ground for everything. Let's impose some structure.
- Database Query - Move get, set, update, add, delete functions together into one db.php file or break them into category-db.php, option-db.php, post-db.php, bookmark-db.php, etc.
- WP Query - Move WP_Query class and all of the functions that wrap the wp_query object (is_*() and the loop functions) into query.php.
- Theme, Stylesheet, Template - Move all of the theming related functions to theme.php.
- Plugin - Move action and filter functions to plugin.php.
- Rewrite/Link - Move WP_Rewrite and supporting functions into rewrite.php.
- Misc - Leave what's left in functions.php.
I'd like to rename existing files while we're at it. The "-functions" suffix and "functions-" prefix aren't necessary. Let's try a three tier naming approach for the bookmark, category, option, post, page, and user functions.
- object-template.php - Template functions
- object-helper.php - Helper funcs for the template funcs
- object-db.php - DB functions that do the get and the set.
We'd have these for each of our objects (bookmarks, categories, ...). Helper functions would be the middle men between the template and db functions. We may not need separate files for helper funcs.
