它使用get_terms 和wp_get_object_terms 内部获取类别。您可以使用与这些函数关联的过滤器来实现所需的功能。

<?php
//$args = apply_filters( \'get_terms_args\', $args, $taxonomies );
add_filter(\'get_terms_args\', \'wpse53900_filter_cat\');
function wpse53900_filter_cat($args, $taxonomies){
    //this is where you can check the taxonomies and roles to filter out the ones you want
    //additionally, make sure to add a check here so that your code runs only on the post edit/add screens
}
