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>
