get_categories() only returns categories in use
提问by John
$args = array(
"type" => "post",
"orderby" => "name",
"order" => "ASC");
$types = get_categories($args);
When this is executed. $types only contains "Uncategorized" since it is used as the default to my posts. There are other categories available, but they are not returned unless I have a post that uses them. How can I return all possible categories and not just the ones that are in use?
执行此操作时。$types 只包含“未分类”，因为它被用作我帖子的默认值。还有其他类别可用，但除非我有使用它们的帖子，否则不会返回它们。如何返回所有可能的类别，而不仅仅是正在使用的类别？

<?php $args = array("hide_empty" => 0,
"type" => "post",
"orderby" => "name",
"order" => "ASC" );
$types = get_categories($args);
?>

For this I suggest to use:
为此，我建议使用：
wp_list_categories( $args );
