wordpress - 自定义分类法中的类别和子类别

Question

我找到并使用以下代码在我的网站上显示默认分类法“类别”的子类别，但我创建了一个自定义分类法，并且无法更改代码以便他为新分类法做同样的事情，请帮助

 <?php

if(is_category()) {
    $subcategories = get_terms('category', 'parent='.get_query_var('cat'));

    if(empty($subcategories)) {
        $thiscat = get_term(get_query_var('cat'),'category');
        $subcategories = get_terms('category', 'parent='.$thiscat->parent.'');
    }
    if(empty($subcategories)) $subcategories = array();
    if(!empty($subcategories)) {
        echo '<ul>';

        foreach($subcategories as $subcat) {
            if(get_query_var('cat') == $subcat->term_id) $current = ' current-cat'; else $current = '';
            echo '
            <li class="cat-item cat-item-'.$subcat->term_id.$current.'">
                <a href="'.get_category_link( $subcat->term_id ).'" title="'.$subcat->description.'">'.$subcat->name.'</a>
            </li>';

        }
        echo '</ul>';
    }
}
else {
    // If no current cat query, just get the top level ones using wp_list_categories.
    ?>
    <ul>
        <?php wp_list_categories('title_li=&depth=1');?>
    </ul>
    <?php
}
?>

事实证明，代码可以按我的意愿工作，但如果可以优化，我将很乐意提供帮助……此代码显示分类法主要类别的子类别。如果有人应该使用，只需将“auto”更改为您的分类名称。我的自定义分类是“自动”

    <?php

if(is_tax()) {
    $subcategories = get_terms('auto', 'parent='.get_queried_object()->term_id);

    if(empty($subcategories)) {
        $thiscat = get_term(get_queried_object()->term_id,'auto');
        $subcategories = get_terms('auto', 'parent='.$thiscat->parent.'');
    }
    if(empty($subcategories)) $subcategories = array();
    if(!empty($subcategories)) {
        echo '<ul>';

        foreach($subcategories as $subcat) {
            if(get_queried_object()->term_id == $subcat->term_id) $current = ' current-cat'; else $current = '';
            echo '
            <li class="cat-item cat-item-'.$subcat->term_id.$current.'">
                <a href="'.get_term_link($subcat,'auto').'" title="'.$subcat->description.'">'.$subcat->name.'</a>
            </li>';

        }
        echo '</ul>';
    }
}
else {
    // If no current cat query, just get the top level ones using wp_list_categories.
    ?>
    <ul>
        <?php wp_list_categories('taxonomy=auto&title_li=&depth=1');?>
    </ul>
    <?php
}
?>

感谢您提供更正的代码。我为那些想要在循环结束后退出的人添加了一些内容。我没有显示父类别树，而是进行了一些修改以显示该特定类别下的产品或服务的图像和标题。以下是代码

if(is_tax()) {
    $subcategories = get_terms('product_categories', 'parent='.get_queried_object()->term_id);
  // this is the change which display all the products in the specific category if it does not have child categories
    if(empty($subcategories)) {
        $thiscat = get_term(get_queried_object()->term_id,'product_categories');
    if (have_posts('thiscat')):while (have_posts('thiscat')) : the_post('thiscat');{?>
        <div class="box cat-item-<?php $subcat->name.$current ;?>" style="min-height: 231px; margin-bottom:10px">
            <a href="<?php the_permalink($post->ID); ?>" title="<?php $post->name ;?>"> <?php the_post_thumbnail('thumbnail');?></a>
        <h5><a title="<?php the_title(); ?>" href="<?php the_permalink($post->ID); ?>"><?php the_title(); ?></a></h5></h5></div>
                    <?php } 

                    endwhile;   
                    else : {

                                ?>
        <div class="box  cat-item cat-item-<?php $subcat->name.$current; ?>" style="min-height: 231px; margin-bottom:10px">
        <h5>Products will be upadated later. Do visit Later </h5 >          
        </div>
                                        <?php }


                endif;
}
if(empty($subcategories)) $subcategories = array();
if(!empty($subcategories)) {
    echo '<div class="fixed-row clearfix dynamic-fixedRow-735" id="row_order_2">';

    foreach($subcategories as $subcat) {
        if(get_queried_object()->term_id == $subcat->term_id) $current = ' current-cat'; else $current = '';
        echo '
        <div class="box cat-item cat-item-'.$subcat->name.$current.'" style="min-height: 231px; margin-bottom:10px"><h5>
            <a href="'.get_term_link($subcat,'product_categories').'" title="'.$subcat->description.'">'.$subcat->name.'</a>
        </h5></div>';

    }
