wp_create_term() WordPress Function

The wp_create_term() function is used to create a new term in the WordPress database. This function takes two arguments: the term name and the term slug. The term name is the name of the term, while the term slug is the URL-friendly version of the term name. The function will return the new term object on success, or false on failure.

	$id = term_exists( $tag_name, $taxonomy );
	if ( $id ) {
		return $id;
	}
