Custom Post Types?They Rock (Seriously)

But what are Custom Post Types?

An example of a post type is posts and pages

PortfolioPost Type could be paintings

Online StorePost Type could be Products

Your only limitation isYour imagination

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

-WordPress Codex

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

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*/

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 );

}

Now lets add to our Custom Post Type

Custom meta dataWith meta boxes

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');

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

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

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');

Capabilities with Custom Post Types

Adding Capabilities to roles

TemplatesFor Custom Post Types

Styling your CPT PageWith single-$posttype.php

Having an Archive Page for your CPTWith archive-$posttype.php

TaxonomiesMore Organization

“Basically, a taxonomy is a way to group things together”

-WordPress Codex

TaxonomiesCategories and Tags

PortfolioTaxonomy is oil painting

add_action('init','wordsesh_tracks‘);

function wordsesh_tracks(){

$tracks_args = array(

'hierarchical' => true,

'query_var' => 'tracks',

'show_tagcloud' => true,

'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',

),

);

register_taxonomy('tracks', array('wordsesh'), $tracks_args);

The array(‘wordsesh’) is our custom post type
