WordPress-列出子类别和子类别，带帖子

我有以下代码。它允许我显示子类别和其中的文档。问题是，一个子类别可能包含更多的子类别。下面的代码将显示属于子（父）级别的子（孙子）类别的文档。

请任何人都能说明如何解决这个问题，以便文档只显示在他们直接所属的类别下面吗？此外，还要强调什么是子-子（孙子）类别？所有帖子标题都应链接到帖子

<?php
$categories =  get_categories(\'child_of=34\');  
foreach  ($categories as $category) {
    //Display the sub category information using $category values like $category->cat_name
    echo \'<h3>\'.$category->name.\'</h3>\';
    echo \'<ul>\';

    foreach (get_posts(\'cat=\'.$category->term_id) as $post) {
        setup_postdata( $post );
        echo \'<li><a href="\'.get_permalink($post->ID).\'">\'.get_the_title().\'</a></li>\';   
    }  
    echo \'</ul>\';
}
?>

下面是一些

第1子类第1子类第4子类第2子类第3子类

<ul class="catArchive"> <?php $catQuery = $wpdb->get_results("SELECT * FROM $wpdb->terms AS wterms INNER JOIN $wpdb->term_taxonomy AS wtaxonomy ON ( wterms.term_id = wtaxonomy.term_id ) WHERE wtaxonomy.taxonomy = \'category\' AND wtaxonomy.parent = 0 AND wtaxonomy.count > 0"); $catCounter = 0; foreach ($catQuery as $category) { $catCounter++; $catStyle = \'\'; if (is_int($catCounter / 2)) $catStyle = \' class="catAlt"\'; $catLink = get_category_link($category->term_id); echo \'<li\'.$catStyle.\'><h3><a href="\'.$catLink.\'" title="\'.$category->name.\'">\'.$category->name.\'</a></h3>\'; echo \'<ul style="margin-left:15px;">\'; query_posts(\'category__in=\'.$category->term_id.\'&showposts=5\');?> <?php while (have_posts()) : the_post(); ?> <li><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a></li> <?php endwhile; ?> <li><a href="<?php echo $catLink; ?>" title="<?php echo $category->name; ?>">More <strong><?php echo $category->name; ?></strong></a></li> <li> <?php $sub_cat_id = $category->term_id; $get_sub_args = array(\'child_of\' =>$sub_cat_id); $categories_arr = get_categories($get_sub_args); //print_r ($categories_arr); foreach ($categories_arr as $sacategory) { //Display the sub category information using $category values like $category->cat_name echo \'<h2>\'.$sacategory->name.\'</h2>\'; echo \'<ul style="margin-left:15px;">\'; foreach (get_posts(\'cat=\'.$sacategory->term_id) as $post) { setup_postdata( $post ); echo \'<li><a href="\'.get_permalink($post->ID).\'">\'.get_the_title().\'</a></li>\'; } echo \'</ul>\'; } ?></li> </ul> </li> <?php } ?> </ul>  </div>
