 */

delete_term_meta()

/**
 * Remove metadata matching criteria from a term.

FAQ

Does this create new database tables?

Yes. It creates a new wp_termmeta database table for each site it's activated on.

Does this modify existing database tables?

No. All of WordPress's core database tables remain untouched.

Does this support querying by metadata?

Yes. It uses the WP_Meta_Query class to create the necessary MySQL. You can interface with it by passing a meta_query argument into get_terms(), by filtering get_terms_args or however else you choose.

Where can I get support?

The WordPress support forums: https://wordpress.org/support/plugin/wp-term-meta/

Can I contribute?

Yes, please! The number of users needing taxonomy term metadata is growing fast. Having an easy-to-use API and powerful set of functions is critical to managing complex WordPress installations. If this is your thing, please help us out!
