1. Creatively Creating
Custom Post Types

#WordSesh2

2. Hi, I’m Nikhil (NikV)
• I develop with WordPress
• I can be found on Twitter @TechVoltz
• Core contributor for WordPress 3.7

3. Custom Post Types?
They Rock (Seriously)

4. But what are Custom Post Types?
An example of a post type is posts
and pages

5. Portfolio
Post Type could be paintings

6. Online Store
Post Type could be Products

7. Your only limitation is
Your imagination

8. “WordPress can hold and display many different
types of content.”
-WordPress Codex

9. Custom Post types should
be added with…
A plugin of course

10. Create a file called myposttype.php
<?php
/**
* Plugin Name: Your Custom Post Type plugin
* Plugin URI: http://yourpluginswebsite.com
* Description: A brief description of your Plugin.
* Version: The Plugin's Version Number, e.g.: 1.0
* Author: Your Name
* Author URI: http://yourwebsite.com
* License: A "Slug" license name e.g. GPL2
*/

11. add_action('init', 'wordsesh_sessions');
function wordsesh_sessions() {
$wordsesh_args = array(
'public' => true,
'query_var' => 'wordsesh',
‘can_export’ => true,
'supports' => array( 'title', 'editor', 'thumbnail', 'excerpt', 'comments', 'page-attributes' ),
'labels' => array(
'name' => 'WordSesh 2 Sessions',
'singular' => 'WordSesh 2 Session',
'add_new' => 'Add Session',
'add_new_item' => 'Add Session',
'edit_item' => 'Edit Session',
'new_item' => 'New Session',
'view_item' => 'View Session',
'search_items' => 'Search Sessions',
'not_found' => 'No sessions found',
'not_found_in_trash' => 'No Sessions found in the Trash',
),
);
register_post_type('WordSesh', $wordsesh_args );
}

12. Now lets add to our
Custom Post Type

13. Custom meta data
With meta boxes

14. Let’s add a meta box
function add_cpt_metabox(){
add_meta_box('cpt_meta', 'Speaker Meta Box', 'cpt_meta',
'wordsesh','side', 'default');
}
add_action('add_meta_boxes', 'add_cpt_metabox');

15. '<input type="text" name=“cpt_meta" value="' . $cpt_meta . '"
class="widefat" />';

16. You can also use…
User roles and Capabilities with
Custom Post Types

17. function delete_wordseshcpt_menu() {
if( !current_user_can( 'administrator' ) ):
remove_menu_page('edit.php?post_type=wordsesh');
endif;
}
add_action('admin_menu', 'delete_wordseshcpt_menu');

19. Capabilities with Custom Post Types

21. Adding Capabilities to roles

23. Templates
For Custom Post Types

24. Styling your CPT Page
With single-$posttype.php

25. Having an Archive Page for
your CPT
With archive-$posttype.php

28. Taxonomies
More Organization

29. “Basically, a taxonomy is a way to group things
together”
-WordPress Codex

30. Taxonomies
Categories and Tags

31. Portfolio
Taxonomy is oil painting

32. add_action('init','wordsesh_tracks‘);

33. function wordsesh_tracks(){
$tracks_args = array(
'hierarchical' => true,
'query_var' => 'tracks',
'show_tagcloud' => true,

34. 'labels' => array(
'name' => 'Tracks',
'edit_item' => 'Edit Track',
'update_item' => 'Update Track',
'add_new_item' => 'Add New Track',
'new_item_name' => 'New Track',
'all_items' => 'All Tracks',
'search_items' => 'Search Tracks',
'popular_items' => 'Popular Tracks',
'add_or_remove_items' => 'Add or remove Tracks',
'choose_from_most_used' => 'Choose from most used Tracks',
),
);

35. register_taxonomy('tracks',
array('wordsesh'), $tracks_args);
The array(‘wordsesh’) is our custom post type
