我一直在用谷歌搜索这个，但搜索起来并不容易。我有一个自定义的层次分类法，大致如下：
Chainsaws
- Electric
- Petrol
- Other
Grasscutters
- Electric
- Petrol
- Other
我最接近的方法是：
$products = get_terms(\'product-type\');
foreach ($products as $product) {
$out .= $product->name;
}
欢迎您提出任何见解。
提前感谢

<?php
$args = array(
\'taxonomy\' => \'product-type\',
\'hierarchical\' => true,
\'title_li\' => \'\',
\'hide_empty\' => false
);
?>
<ul>
<?php wp_list_categories( $args ); ?>
</ul>
以下是我突然想到的：
<?php
//Walker function
function custom_taxonomy_walker($taxonomy, $parent = 0)
{
$terms = get_terms($taxonomy, array(\'parent\' => $parent, \'hide_empty\' => false));
//If there are terms, start displaying
if(count($terms) > 0)
{
//Displaying as a list
$out = "<ul>";
//Cycle though the terms
foreach ($terms as $term)
{
//Secret sauce. Function calls itself to display child elements, if any
$out .="<li>" . $term->name . custom_taxonomy_walker($taxonomy, $term->term_id) . "</li>";
}
$out .= "</ul>";
return $out;
}
return;
}
//Example
echo custom_taxonomy_walker(\'category\');
?>
