Wordpress:仅显示顶级类别

Question

我正在使用这段代码:

$args = array(
  'orderby' => 'name',
  'hierarchical' => 1,
  'style' => 'none',
  'taxonomy' => 'category',
  'hide_empty' => 0,
  'depth' => 1,
  'title_li' => ''
);

$categories = get_categories($args);

我想要做的是只列出顶级类别。当我使用这段代码时，我得到的不仅仅是一级。有人能帮我吗？

没有depth get_categories() 的论据， 你应该试试 :

$args = array(
  'orderby' => 'name',
  'parent' => 0
);

parent : (integer) Display only categories that are direct descendants (i.e. children only) of the category identified by its ID. This does NOT work like the 'child_of' parameter. There is no default for this parameter. [In 2.8.4]
