尝试使用以下代码覆盖已注册分类的参数。

function wp_modify_taxonomy() {

    // get the arguments of the already-registered taxonomy
    $custom_category_args = get_taxonomy( \'genre\' );

    // make changes to the args
    $custom_category_args->rewrite[\'slug\'] = \'chambers\';
    $custom_category_args->rewrite[\'with_front\'] = false;

    // re-register the taxonomy
    register_taxonomy( \'genre\', \'chambers\', (array) $custom_category_args );
}
add_action( \'init\', \'wp_modify_taxonomy\', 11 );
