Building Custom Post Type Generator

Let’s start building our central custom post type generator. This is the module that handles:

• Receiving all of the custom post type configurations in your project
• Loop through each of them to do the following:
  • Generate the features supported by the custom post type
  • Generate the labels
  • Build the arguments
  • and then register the custom post type with WordPress

We’ll start by copying and pasting the code from our FAQ module into the new Custom module. Then we’ll start working on refactoring it. Our goal is to remove all of the specific implementation code, i.e. to make it generic and reusable to handle any custom post type.

Imagine that you have a project where you are building a typical business-centric website for a client. This client wants FAQs, Portfolios, and Testimonials. Those are typical components in a business website. Each of those is a perfect custom post type candidate. Therefore, your project could have at least three separate custom post types.

Now, look at the FAQ module. You wouldn’t want to repeat the code for the portfolio or testimonial. Why? Because it’s redundant, error-prone, and time-consuming. Think about it. One change and you have to go to three separate places to change it. You have to remember to change all three of the custom post types. That’s highly inefficient and wasteful.

Rather, our reusable module houses all of the code we need. We just pass a configuration to it for the FAQ, portfolio, and testimonial. Then it handles the work and registration for us. Now if a change happens, it’s in one place. That’s more efficient and a better strategy for building code.
