apply_filters( 'wp_insert_term_duplicate_term_check', object $duplicate_term, string $term, string $taxonomy, array $args, int $tt_id )

Filters the duplicate term check that takes place during term creation.

Description Description

Term parent+taxonomy+slug combinations are meant to be unique, and wp_insert_term() performs a last-minute confirmation of this uniqueness before allowing a new term to be created. Plugins with different uniqueness requirements may use this filter to bypass or modify the duplicate-term check.

Parameters Parameters


(object) Duplicate term row from terms table, if found.


(string) Term being inserted.


(string) Taxonomy name.


(array) Term arguments passed to the function.


(int) term_taxonomy_id for the newly created term.
