With new possibilities of WP3+, custom taxonomies, custom post types, is there a way to create, without the use of a plugin a custom field with or without predefined values to choose from ?
Thank you
Add pre-defined custom fields in WordPress without plugin
Maybe you need to look at custom meta boxes….
You can completely control extra data for specific posts in their own separate box.
Codex link:
add_meta_box – Docs – WordPress
You will need to hook in to the ‘save_post’ action hook to save your custom data.
