Complete Code to Register Custom Post Types and Custom Taxonomies in WordPress — a practical guide to Complete Code to Register Custom Post Types and Custom Taxon with clear examples you can reuse in real projects.
In this example, we’ll create two custom post types Testimonials and Projects using the register_post_type() function. We’ll also register four custom taxonomies Type, Material, Service, and Category for the Projects post type using the register_taxonomy() function.
Simply add the following code to your theme’s functions.php file or a custom plugin. Once added, you’ll see the new post types and taxonomies in the WordPress admin dashboard, allowing you to organize and manage your content more efficiently.
