Dive Into WordPress Custom Post Types – Part 3

Last updated March 8th, 2023 at 09:59 am

Before I get into the techniques of creating custom post types, I want to step back and look at the larger issue of custom content.

Custom Post Type < > Custom Content

The title of this series is “Dive into WordPress Custom Post Types”.

But I cannot emphasize enough that, technically, a custom post type — as in the thing you create using the register_post_type() function — is merely the foundational component of what I think of (and what I recommend you think of) as a “custom content module”. In fact, registering a custom post type is probably the simplest and easiest part of creating a custom content module.

Custom Content Module Defined

I define a custom content module as consisting of these components:

• the registered custom post type (required, duh)
• custom fields (technically optional but practically required)
• custom taxonomy/ies (optional)
• custom templates for displaying custom content on the front end (required)

I say that custom fields are practically required though technically optional because without them, a custom post type is nothing more than a post or a page (depending on what you specified when registering it).

(Yes, I suppose you could create a new post type without custom fields for content you want to keep separate from your default blog. But there are other ways to achieve this kind of segmentation, like with standard categories and post tags. Anyway, if you disagree with me, I certainly welcome your comments.)

What I’m Talking About in this Series

The types of custom content I’ll be talking about are similar to the examples from the first post in this series:

• Books you’ve authored (or read)
• Staff directory
• Testimonials
• Favorite movies
• Recipes
• Frequently Asked Questions
• Board of Directors

Up Next

My plan for the next post in this series is to put it all together using a real-world solution implemented in one of my web projects.

If you haven’t already done so, check out and bookmark the WordPress codex documentation for register_post_type().
