基本上正如标题所说，我想获得类别和子类别的列表，然后针对这些类别/子类别发布文章（带有链接）。
这就是我试图实现的结构：
第1类第1子类第1子类第2子类第2子类第1子类第2子类第2子类第2子类第1子类第3子类子类别2中的第3个帖子子类别1中的子类别1中的子类别1中的子类别1中的子类别2中的子类别32在子类别2内，第3篇在子类别2内，第3篇在子类别2内，第2篇在子类别2内，第1篇在子类别2内，第2篇在子类别2内，第3篇在子类别2内，第1篇在子类别2内第一篇没有子类别的帖子，目前为止，在阅读了关于该主题的所有内容后，我有以下代码：
<ul>
<?php
$get_parent_cats = array(
\'parent\' => \'0\' //get top level categories only
);
$all_categories = get_categories( $get_parent_cats );//get parent categories
foreach( $all_categories as $single_category ){
//for each category, get the ID
$catID = $single_category->cat_ID;
echo \'<li><a href=" \' . get_category_link( $catID ) . \' ">\' . $single_category->name . \'</a>\'; //category name & link
$get_children_cats = array(
\'child_of\' => $catID //get children of this parent using the catID variable from earlier
);
$child_cats = get_categories( $get_children_cats );//get children of parent category
echo \'<ul class="children">\';
foreach( $child_cats as $child_cat ){
//for each child category, get the ID
$childID = $child_cat->cat_ID;
//for each child category, give us the link and name
echo \'<a href=" \' . get_category_link( $childID ) . \' ">\' . $child_cat->name . \'</a>\';
}
echo \'</ul></li>\';
} //end of categories logic ?>
</ul>
现在，这段代码很好地显示了类别和子类别，但我需要以某种方式循环浏览我的帖子，并用类别/子类别显示它们。我还尝试使用休闲代码：
<?php
// get all the categories from the database
$cats = get_categories();
// loop through the categries
foreach ($cats as $cat) {
// setup the cateogory ID
$cat_id= $cat->term_id;
// Make a header for the cateogry
echo "<h2>".$cat->name."</h2>";
// create a custom wordpress query
query_posts("cat=$cat_id&posts_per_page=100");
// start the wordpress loop!
if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php // create our link now that the post is setup ?>
<a href="<?php the_permalink();?>"><?php the_title(); ?></a>
<?php echo \'<hr/>\'; ?>
<?php endwhile; endif; // done our wordpress loop. Will start again for each category ?>
<?php } // done the foreach statement ?>
</div><!-- #content -->
</div><!-- #container -->
此代码显示特定类别中的所有类别和帖子，但结构不是我想要的。两天来，我一直在尝试将这两段代码组合在一起，但我尝试的结果都不符合我的要求。我对Wordpress没有经验，我真的需要帮助。

此函数可以立即运行，只需确保将名称更改为您自己的分类法和帖子类型即可。请随意阅读评论以了解更多说明。
