This document discusses custom post types and taxonomies in WordPress. It explains that custom post types allow adding different content types beyond standard posts and pages. Taxonomies allow categorizing and tagging custom content. Plugins can easily create these, or they can be coded manually. Templates and queries must also be customized to display and retrieve custom content types and taxonomies. Custom fields further extend content by adding specific metadata.

3. What is a Post Type? Posts and pages and more! Oh my!

4. How Do They Work? Should be called “Content Types” Content goes into the posts table Each content item is assigned a post_type The queries output the content The default post type is ‘post’

5. Built in Types Main Content Post – blog style content Page – static content Other Attachment – any images or other files uploaded to a post (of any type) Revision – an archive of versions of a particular post Nav Menu Item – Used in the new menu system

6. Custom Types Employees Products … any content that needs to be stored and used differently than blog posts or static pages Won’t show up in main RSS feed

7. What Isn’t a Post Type? Asides and galleries and links! Oh my!

13. Custom Taxonomies Employee departments Product categories … any way you want to tag or categorize your custom post types Can be used with blog posts and static pages as well Multiple taxonomy query coming in WordPress 3.1 Use Query Multiple Taxonomies plugin

14. Hand Coding The hard way

15. Register a Post Type function post_type_movies(){ register_post_type('movies', array('label'=> __('Movies'), 'public'=>true, 'show_ui'=>true, 'supports' =>array( 'post-thumbnails', 'excerpts', 'trackbacks', 'custom-fields', 'comments', 'revisions') ) ); register_taxonomy_for_object_type('post_tag', 'movies'); } add_action('init', 'post_type_movies'); First Impressions of Custom Post Type by Frank Bültge on WPEngineer.org http://bit.ly/posttypes

16. Default Arguments // Args prefixed with an underscore are reserved for internal use. $defaults =array( 'label' =>false, 'publicly_queryable' => null, 'exclude_from_search' => null, '_builtin' =>false, '_edit_link' =>'post.php?post=%d', 'capability_type'=>'post', 'hierarchical' => false, 'public' => false, 'rewrite' =>true, 'query_var' =>true, 'supports' =>array(), 'register_meta_box_cb' => null, 'taxonomies' =>array(), 'show_ui' => null ); First Impressions of Custom Post Type by Frank Bültge on WPEngineer.org http://bit.ly/posttypes

17. The Taxonomy Code function post_type_movies(){ … register_taxonomy('actor', 'movies', array( 'hierarchical'=>true, 'label'=> __('Actor') ) ); register_taxonomy(‘director', 'movies', array( 'hierarchical'=>false, 'label'=>__(‘Director'), 'query_var'=>‘director', 'rewrite' =>array('slug'=>‘director') ) ); } add_action('init', 'post_type_movies'); First Impressions of Custom Post Type by Frank Bültge on WPEngineer.org http://bit.ly/posttypes

18. Using Plugins The easy way

19. “ Overheard WordCamp Birmingham 2009 WordPress is the iPhone of the internet. You’ll always hear, “There’s a plugin for that!”

20. Plugins for Creating Them Custom Post Type UI Creates both TONS of labeling options WP Post Type UI Creates both Buggy Allows a custom icon More Types & More Taxonomies Allows you to override built in types and taxonomies Allows a custom icon Works seamlessly with the More Fields plugin (stay tuned for more)

21. Plugins for Manipulating Them Custom Post Type Order Drag and drop ordering Simple Custom Post Type Archives Adds support for custom post type archive permalinks Adds new body classes to custom post type archives Adds a new conditional, is_custom_post_type_archive Fixes the wp_title output on custom post type archives to show the custom type's label Adds custom post type feeds And more… Post Type Switcher Change the post type one item at a time Convert Post Types Bulk edit post types

22. Custom Templates Now what do I do?

23. Template Hierarchy Custom Post Type single-{post_type}.php single.php index.php Custom Post Types Display Coming in version 3.1 Use Simple Custom Post Type Archives plugin Custom Taxonomy taxonomy-{taxonomy}-{term}.php taxonomy-{taxonomy}.php taxonomy.php archive.php index.php

24. Custom Loops & Queries This gets hardcore

25. The Loop The Basic Loop <? $loop =newWP_query('post_type=movies'); while ($loop->have_posts()): $loop->the_post(); ?> ... Do Stuff Here ... <?endwhile; ?> Add Custom Taxonomies $loop =newWP_query('post_type=movies&actor=joaquin-phoenix'); $loop =newWP_query('post_type=movies&actor=joaquin-phoenix&director=m-night-shyamalan');

26. Term Lists Get All Terms $terms =get_terms('actors', 'order_by=count&order=DESC'); Get Terms in a Post get_the_term_list( $post->ID, 'actors', '<p>Actors: ', ',', '</p>' ) Other Functions get_term get_term_children get_term_by get_taxonomies

27. More Custom Content But wait, there’s more!

28. “ Matt Mullenweg WordCamp Birmingham 2009 I like what you’re doing; I just don’t like the way you’re having to do it. So I’m going to make it better.

29. No More Flutter Custom Post Types to create the special content Custom Taxonomies to organize the content Custom Fields to get specific information on each post in a way that is human and pretty

30. Customized Custom Fields Plugins More Fields Builds pretty boxes with custom types of custom fields Works perfectly with More Types and More Taxonomies Custom fields Widget-like interface Doesn’t seem to interact with custom post types Easy Custom Fields Just as much coding as the hand coded method … not so easy Hand Coded add_meta_box() Basically limitless Lots o’ code WordPress.org Codexhttp://bit.ly/metabox01 Tutorial at Deluxe Blog Tipshttp://bit.ly/metabox02 We Function Tutorialhttp://bit.ly/metabox03
