This is a convenience class and collection of methods to make creating new custom post types with their own metaboxes easy.
The general idea is to define a function that’s hooked to the <code>register_post_types</code> action. The function defines a class for your post type that extends the <code>GO_Cpt</code> class. This follows a design pattern established by the modern widgets API (as introduced in WP 2.8) https://codex.wordpress.org/Widgets_API#Developing_Widgets .
The result is a new custom post type and much easier creation and updating of custom meta associated with that post type. You’ll also have a convenient object you can use to access the metadata associated with each post.
<pre><code>function my_customposttype() { class My_CustomPostType extends GO_Cpt { function __construct() { // execute the parent constructor with the name 
 // and definition for the custom post type parent::__construct( $post_type_name , $post_type_definition ); } function metabox( $post , $meta ) { // print out the form here // 
 // this method is optional, only use it if you want to 
 // add a metabox to your custom post type } function update( $new_meta , $old_meta ) { // sanitize and validate the metadata // then return $meta so it can be saved // // this method is required if a 
 // metabox() method is included } } global $my_customposttype; $my_customposttype = new My_CustomPostType; } // hook that function to the register_post_types action add_action( 'register_post_types' , 'my_customposttype' ); </code></pre>
Backstory: defining the post type class inside the function avoids issues with loading order and fatal errors resulting from attempting to extend a class that might not exist yet. Isn’t PHP awesome?
See the included hello world example: https://plugins.trac.wordpress.org/browser/go-cptfactory/trunk/example-helloworld-cpt.php
To access the meta associated with a post, you can call <code>$my_customposttype->get_meta( $post_id );</code>
You can easily add a method and hook to filter <code>the_content</code> or <code>the_excerpt</code> to insert custom values that may have been entered in the post meta. Simply add <code>add_filter( 'the_content' , array( $this , 'the_content' ));</code> in the <code>__construct()</code> and then define another method in the <code>My_CustomPostType</code> class such as:`
<pre><code> function the_content( $content ) { 
 $meta_print = print_r( $this->get_meta( get_the_ID() ) , TRUE ); 
 return $meta_print . $content 
 } </code></pre>

When working on WordPress themes, we tend to use a lot of custom post types. This gives the end- user custom little sections to manage content in. Often enough we see the need to be able to feature posts or custom posts of custom post types (cpts).
This can be accomplished by using a bunch of different Featured Posts Plugins. And we probably have used all of them over the years. To date we have yet to find one that didn’t conflict or break somehting in our WordPress themes. So we created our own, to be specifc we created our own to be easily used with Posts, Custom Posts, and with the Simple Page ordering plugin that we install on every WordPress Theme that we develop.
To use:
<ol>
<li>Download the feature-posts-and-custom-posts.zip file to your computer.</li>
<li>Unzip the file.</li>
<li>Upload the feature-posts-and-custom-posts folder to your /wp-content/plugins/ directory.</li>
<li>Activate the plugin through the Plugins menu in WordPress.</li>
<li>In your theme and in the template you need the featured functionality uses a custom query like this query_posts("post_type=professionals&posts_per_page=-1&meta_key=_jsFeaturedPost&meta_value=yes"); to grad all of the featured posts.</li>
</ol>
