According his comment:
- Added a
get_meta_{$type}system, similar to how you hadshow_field_{$type}functions. This allows you to do a number of things: pre-format metadata before you display it or pull data from other sources other than the custom fields/ postmeta table. - Taxonomy type. Extended from original version. It uses a custom
get_meta_taxonomyto pull terms from the taxonomy system. It also uses jQuery to support hierarchical taxonomies. - Rehauled the image system. Now you don’t need to save the images as metadata: I created a
get_meta_imagesfunction that does a query of all the attached image ids and returns that as the meta. - Added
get_field_nameandget_field_idfunctions. You could change the way you set the name or id attributes of your fields so you could support more complex meta boxes, like ones that pull data from multiple other posts of different post types. - Parent type allows you to set the post_parent of a post, creating a hierarchical structure across multiple post types. The
parent_typeis the custom post type of the parent you want. It then gives you a select field that lets you pick from a list of all the posts of that type. The one you pick gets stored in the post’s post_parent field in the wp_posts table automatically. Cool part is that WordPress saves it automatically because the field’s name is post_parent. No save function required.
Add menu select box
This code is written by Asafche. Actually, it’s not a class. It’s just an additional method for new field type. But it worths a try (if you need it, of course).
Sliders
Pippin Williamson wrote this extended class that help users to create Sliders. Refer to his comment to know how to use it.
