How can I create a custom post type with its own taxonomy?

Asked on Nov 30, 2025

Answer

Creating a custom post type with its own taxonomy in WordPress involves using the `register_post_type` and `register_taxonomy` functions. This allows you to organize content into distinct types and categories beyond the default posts and pages.

<!-- BEGIN COPY / PASTE -->
    function my_custom_post_type() {
        // Register the custom post type
        register_post_type('book', array(
            'labels' => array(
                'name' => __('Books'),
                'singular_name' => __('Book')
            ),
            'public' => true,
            'has_archive' => true,
            'rewrite' => array('slug' => 'books'),
            'supports' => array('title', 'editor', 'thumbnail')
        ));

        // Register the custom taxonomy
        register_taxonomy('genre', 'book', array(
            'labels' => array(
                'name' => __('Genres'),
                'singular_name' => __('Genre')
            ),
            'hierarchical' => true,
            'rewrite' => array('slug' => 'genres')
        ));
    }
    add_action('init', 'my_custom_post_type');
    <!-- END COPY / PASTE -->

Additional Comment:

Place this code in your theme's `functions.php` file or a custom plugin.
Adjust the labels and settings to suit your content needs.
Ensure permalinks are refreshed by visiting Settings → Permalinks after adding the code.
Custom post types and taxonomies can be managed in the WordPress dashboard under their respective new menu items.
