只显示帖子的子类别

Question

我有一个自定义帖子，我想显示它的一部分的所有类别。有两个部分这一点，在页面我只显示了顶级类别，它的一部分的顶部，这是我做的：

<?php $term_list = wp_get_post_terms($post->ID, 'project-categories', array('fields' => 'all', 'parent' => 0)); 
foreach($term_list as $term) { ?> 

    <div class="type-block"> 
     <span class="type-initial"><?php echo the_field('category_initials', 'project-categories_' . $term->term_id); ?></span> 
     <span class="type-name type-name-<?php echo $term->term_id; ?>"><?php echo $term->name; ?></span> 
    </div>        

<?php } ?> 

走向我想在页面的底部只显示它所属的子类别 - 这些子类别可能是几个顶级类别的一部分。我如何显示它们？这是我的尝试：

<?php $term_list = wp_get_post_terms($post->ID, 'project-categories', array('fields' => 'all', 'parent' => array(7, 10, 8, 9, 11))); 
foreach($term_list as $term) { ?> 

    <div class="type-block type-block-black"> 
     <span class="type-initial"><?php echo the_field('category_initials', 'project-categories_' . $term->term_id); ?></span> 
     <span class="type-name type-name-<?php echo $term->term_id; ?>"><?php echo $term->name; ?></span> 
    </div>        

<?php } ?> 

目前它只显示最后一个子类别，如何显示多个类别？

试试这个代码

<?php 
    $term_list = wp_get_post_terms($post->ID, 'project-categories', array('fields' => 'all')); 
    $term_list = wp_list_filter($term_list, array('parent'=>'0'),'NOT'); 
    foreach($term_list as $term) { ?> 

     <div class="type-block type-block-black"> 
      <span class="type-initial"><?php echo the_field('category_initials', 'project-categories_' . $term->term_id); ?></span> 
      <span class="type-name type-name-<?php echo $term->term_id; ?>"><?php echo $term->name; ?></span> 
     </div>        

<?php } ?>
