笨小兔很多实用dux主题的小伙伴，都因为dux本身没有设置一些功能而用来不方便，比如没有禁止古腾堡小工具啥的，笨小兔根据自己的使用习惯，准备了一下dux主题自定义代码，可以让dux更好用。
可以将下面代码段放入dux主题目录中的functions.php文件的// Customize your functions下面即可。
笨小兔已经做好每个代码的注释，自己根据需求选择。
//标签自动别名
add_action('create_term', 'my_custom_term_slug', $priority = 10, $accepted_args = 3);
function my_custom_term_slug($term_id, $tt_id, $taxonomy) {

wp_update_term($term_id, $taxonomy, $args = array('slug' => 't-' . $term_id));
}
}
