Wordpress自定义类别层次结构
我有一个循环,除了它没有以分层的方式输出所有类别之外,它是有效的。相反,它们都是按字母顺序排列的Wordpress自定义类别层次结构,wordpress,categories,hierarchy,Wordpress,Categories,Hierarchy,我有一个循环,除了它没有以分层的方式输出所有类别之外,它是有效的。相反,它们都是按字母顺序排列的 <?php $categories = get_categories('hierarchical=1&order=ASC&hide_empty=0'); foreach ($categories as $cat) { $posts = new WP_Query( array('hierarchical' => 1, 'cat' => $ca
<?php
$categories = get_categories('hierarchical=1&order=ASC&hide_empty=0');
foreach ($categories as $cat) {
$posts = new WP_Query( array('hierarchical' => 1, 'cat' => $cat->cat_ID));
?>
<div class="project">
<h2><?php echo $cat->cat_name; ?>/h2>
</div>
<?php
}
?>
…但我需要它们像这样输出(按字母顺序排列的列表,但顺序正确):
我希望它们按字母顺序出现,但也显示父母/兄弟姐妹关系
我不需要担心添加一个类或兄弟类或任何东西(我缩进了上面的列表只是为了演示),而平面列表仍然可以,只要顺序正确
提前感谢。使用wp\u列表\u类别

这只会产生一个无序的列表,这不是我想要实现的。正如您在代码示例中看到的,我正在使用divs。代码示例显示得很简单,但实际上我也将在div中添加许多其他标记。
