首先，使用为给定类型的帖子注册分类法get_object_taxonomies(). 然后检查哪些是分层的，例如使用is_taxonomy_hierarchical() conditional tag. 最后一步是显示列表。

// current post ID
$post_id = get_the_ID();
// taxonomies registered for this type of posts
$taxonomies = get_object_taxonomies( get_post_type() );

$taxs_tree = [];   // hierarchical taxonomies
$taxs_flat = [];   // non-hierarchical taxonomies
foreach ( $taxonomies as $tax )
{
    if ( is_taxonomy_hierarchical( $tax ) )
        $taxs_tree[] = $tax;
    else
        $taxs_flat[] = $tax;
}

从每个分类中获取术语并显示它们。

// get terms as links
$terms_flat = $terms_tree = [];
foreach ( $taxs_tree as $tax ) {
    $terms_tree[] = get_the_term_list( $post_id, $tax );
}
foreach ( $taxs_flat as $tax ) {
    $terms_flat[] = get_the_term_list( $post_id, $tax );
}

echo \'<span id="one">\';
foreach ( $terms_tree as $links ) {
   echo $links;
}
echo \'</span>\';

或：

//
// terms assigned to post, ordered by name, from all hierarchical taxonomies
$args = [
   \'taxonomy\'   => $taxs_tree,   // here you can pass array of taxonomies
   \'object_ids\' => get_the_ID(), // get only terms assigned to this post (current post)
   //\'orderby.  => \'name\',       // default
];
$terms_tree = get_terms( $args ); // array of WP_term objects

//
// terms assigned to post, ordered by name, from all non-hierarchical taxonomies
$args[\'taxonomy\'] = $taxs_flat;
$terms_flat = get_terms( $args ); // array of WP_term objects

//
// display 
echo \'<span id="one">\';
foreach ( $terms_tree as $term ) {
    $link = get_term_link( $term );
    if ( is_wp_error( $link ) ) {
        continue;
    }
    echo \'<a href="\' . esc_url( $link ) . \'" rel="tag">\' . $term->name . \'</a> \';
}
echo \'</span>\';

// the same with $terms_flat

第二种解决方案（使用get_terms) 对术语排序from all 按名称划分的层次分类法，而第一个get_the_term_list) 对术语排序from each 层次分类法separately.
