}
add_action('init', 'create_custom_post_type_books', 0);### Key Points in the Code:
– **Labels**: Define how the custom post type will appear in the admin panel.
– **Supports**: Specify which WordPress features the post type supports (e.g., title, editor, thumbnail).
– **Menu Icon**: Set the icon using a [Dashicons](https://developer.wordpress.org/resource/dashicons/).
– **Show in REST**: Enables the post type to use the Gutenberg editor and APIs.
– **Has Archive**: Set to `true` to create an archive page for the custom post type.
### Activating the Custom Post Type:
– Add the code to your theme’s `functions.php` file or create a custom plugin.
– Visit the WordPress admin and refresh permalinks by navigating to **Settings > Permalinks** and clicking **Save Changes**.
### Customizing the Output:
You can customize the display of your custom post type using template files:
– **Single Post**: `single-book.php`
– **Archive Page**: `archive-book.php`
Create these files in your theme directory to control how individual posts and archives of the custom post type are displayed.
