What’s $genres
? I don’t see it defined anywhere.
And wp_insert_term()
may return an error, so make sure to check if it is an error. So instead of simply doing return wp_insert_term($name,$tax)["term_id"]
, you could do something like this:
$data = wp_insert_term( $name, $tax );
if ( ! is_wp_error( $data ) ) {
return $data['term_id'];
}
