按分類術語顯示自定義文章類型列表

Question

我需要顯示按術語分類的自定義文章類型列表。我們的想法是這樣的：

服務列表：

<ul> 
<li> 
    <a href="#">Webdesign (taxonomy term)</a> 
    <ul> 
    <li>Business Website A (custom post type from this taxonomy term)</li> 
    <li>Business Website B (custom post type from this taxonomy term)</li> 
    <li>Business Website C (custom post type from this taxonomy term)</li> 
    </ul> 
</li> 
<li> 
    <a href="#">Illustration (taxonomy term)</a> 
    <ul> 
    <li>Business Illustration A (custom post type from this taxonomy term)</li> 
    <li>Business Illustration B (custom post type from this taxonomy term)</li> 
    <li>Business Illustration C (custom post type from this taxonomy term)</li> 
    </ul> 
</li> 
<li>Other service without taxonomy (if has no taxonomy, show in first level)</li> 
</ul> 

我已經試過wp_list_pages和wp_list_categories，但沒有成功。

• 有人可以給我一個提示如何進行？

您可以使用get_posts或WP_Query與分類參數：

例與get_posts：

<ul> 
    <li> 
     <a href="#">Webdesign</a> 
     <ul> 
<?php $items = get_posts(array(
    'post_type' => 'my_post_type', 
    'tax_query' => array(
     array(
      'taxonomy' => 'my_taxonomy', 
      'field' => 'slug', 
      'terms' => 'webdesign' 
     ) 
    ) 
)); 
if($items){ 
    foreach ($items as $item){ 
     setup_postdata($item); 
     echo '<li>' . get_the_title($item->ID) . '</li>'; 
    } 
} ?> 
     </ul> 
    </li> 
</ul>
