说明

This function adds or overwrites a taxonomy. It takes in a name, an object name that it affects, and an array of parameters. It does not return anything.

Care should be used in selecting a taxonomy name so that it does not conflict with other taxonomies, post types, and reserved WordPress public and private query variables. A complete list of those is described in the Reserved Terms section.
