8. Your only limitation is Your imagination
9. “WordPress can hold and display many different types of content.” -WordPress Codex
10. But how do we add Custom Post Types? With a plugin of course
11. Create a file called myposttype.php <?php /** * Plugin Name: Your Custom Post Type * 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 */
12. add_action('init', 'wordup_sessions'); function wordup_sessions() { $wordup_args = array( 'public' => true, 'has_archive' => true, 'query_var' => 'wordup', 'menu_position' => 5, 'supports' => array( 'title', 'editor', 'thumbnail', 'excerpt', 'comments' ), 'labels' => array( 'name' => 'WordUp Sessions', 'singular' => 'WordUp 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 WordUp', 'not_found' => 'No sessions found', 'not_found_in_trash' => 'No Sessions found in the Trash', ), ); register_post_type('WordUp', $wordup_args ); }

28. add_action('init', 'wordup_tracks');
29. function wordup_tracks(){ $track_args = array( 'hierarchical' => true, 'query_var' => ‘wordup_tracks', 'show_tagcloud' => true,
30. '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', ), );
31. register_taxonomy(‘wordup_tracks', array('wordup'), $dev_args); } The array(‘wordup’) is our custom post type
