Define hooks

Additional hooks are supported with the hooks() method.

Here you can register additional actions and filters to WordPress and allows you to keep logic associated with your post type in one class.

use PostTypes\PostType;
use WP_Post;

class Books extends PostType
{
    //...

    /**
     * Adds additional hooks for the post type.
     *
     * @return void
     */
    public function hooks(): void
    {
        add_action( 'save_post_book', [ $this, 'onSave' ], 10, 3 );
    }

    /**
     * Run additional logic when saving a Books post.
     *
     * @param int $post_id
     * @param WP_Post $post
     * @param bool $update
     * @return void
     */
    public function onSave(int $post_id, WP_Post $post, bool $update)
    {
        // Run additional logic when a Books post type is saved...
    }
}
