Function Name: register_taxonomy_for_object_type

Explanation: The register_taxonomy_for_object_type function in WordPress is used to associate a custom taxonomy with a specific post type. This means that when the specified post type is registered or updated, the custom taxonomy will be available for use with that post type.

This function is particularly useful when you want to organize and categorize your content using custom taxonomies. By associating a taxonomy with a specific post type, you can create a structured and hierarchical system for classifying and filtering your content.

Example Usage Code: Let’s say you have a custom post type called "Books" and you want to associate a custom taxonomy called "Genres" with it. You can use the register_taxonomy_for_object_type function as follows:

function custom_taxonomy_for_books() {
    register_taxonomy_for_object_type('genre', 'books');
add_action('init', 'custom_taxonomy_for_books');

In this example, we define a function named "custom_taxonomy_for_books" that uses the register_taxonomy_for_object_type function to associate the "genre" taxonomy with the "books" post type. We then hook this function to the ‘init’ action, ensuring that it is executed when WordPress initializes.

Once this code is implemented, you will be able to assign genres to the "Books" post type, providing a way to categorize and filter your book content based on genres.
