7. What the @#$*! is a Custom
Post Type?
Also referred to as CPTs
3/24/12 Custom Post Types and Taxonomies 7

8. CPTs - from the Codex
“WordPress can hold and display many different types of
content. Internally, these are all stored in the same place,
in the wp_posts table.
These are differentiated by a column called post_type.
WordPress 3.0 gives you the capability to add your own
custom post types and to use them in different ways.”
http://codex.wordpress.org/Post_Types

26. Generally there are two different
methods used for a “slideshow”
custom post type…
3/24/12 Custom Post Types and TaxonomiesCustom Post Types and Taxonomies

27. First method
• The entire post type is one slideshow
• Each entry (post) is a slide
• Featured image is the slide image
• hierarchial=false (register cpt)
• orderby=menu_order (wp_query)
• Fancy AJAX re-ordering, eg:

28. First method – back end

29. First method – front end
3/24/12 Custom Post Types and Taxonomies 29

30. Second method
• Each entry (post) is a complete slideshow
• Usually has a shortcode system
eg [slideshow id=21]
• Often has more bells and whistles, though can
be more work to customize
