What is register_taxonomy?

register_taxonomy() is a WordPress function that allows you to register a custom taxonomy. Taxonomies are used to organize your content into categories and tags. For example, you could create a taxonomy called "genre" to categorize your blog posts by genre, or a taxonomy called "tags" to allow your users to tag their posts with relevant keywords.

How to use register_taxonomy

To use register_taxonomy, you will need to pass the following arguments to the function:

• taxonomy: The name of the taxonomy.
• object_type: The type of object that the taxonomy will be associated with. For example, if you are creating a taxonomy for blog posts, you would use "post" as the object_type.
• args: An array of arguments that control the behavior of the taxonomy. These arguments are optional, but there are a few that you will likely want to set, such as the hierarchical argument, which determines whether the taxonomy is hierarchical (like categories) or non-hierarchical (like tags).

Here is an example of how to use register_taxonomy:

PHP

register_taxonomy(
  'genre',
  'post',
  array(
    'hierarchical' => true,
    'labels' => array(
      'name' => 'Genres',
      'singular_name' => 'Genre',
      'search_items' => 'Search Genres',
      'popular_items' => 'Popular Genres',
      'all_items' => 'All Genres',
      'edit_item' => 'Edit Genre',
      'update_item' => 'Update Genre',
      'add_new_item' => 'Add New Genre',
      'new_item_name' => 'New Genre Name'
    ),
    'query_var' => true,
    'rewrite' => array(
      'slug' => 'genre',
      'with_front' => false
    )
  )
);

Use code with caution.
