各WooCommerce親カテゴリの既存のサブカテゴリの合計数を取得

Question

私は既に私のレイアウトを達成するためにwoocommerce archive-product.phpファイルを編集しましたが、私が把握する必要があるものはまだあります。各ページをアーカイブする際に既存のサブカテゴリの総数を表示したい。

私はそれらの一つ一つは、いくつかのサブカテゴリを持っていることを二つの主要な製品カテゴリ（A、B）を持っている。例えば

：

Category A 
    Subcategory A1 
    Subcategory A2 

Category B 
    Subcategory B1 
    Subcategory B2 
    Subcategory B3 

私はそれぞれの親のサブカテゴリの数を表示したい、私の場合2でAアーカイブページのサブカテゴリとBアーカイブページの3サブカテゴリ。

これは私がこれまで何をやったかである：

そしてこれは私の問題に関連した一部です：

<?php 

           $taxonomyName =get_query_var('product_cat'); // use use get_queried_object()->taxonomy; to get the current taxonomy name 
           $countchildren = count (get_term_children($term_id, $taxonomyName)); 

        echo '<h3 class="group-products mts mbm cat-title text-underline">'.'<span class="big">'.'Products Families'.'<span class="cont-post">'.'(' .$countchildren.')'.'</span>'.'</span>'.'</h3>'; 

        ?> 

任意のヘルプのヘルプをいただければ幸いです。あなたは、単にこの方法を数える子カテゴリを取得するにはget_term_children()機能を使用することができます

Answer 1

：

$countchildren = count(get_term_children($queried_object->term_id, 'product_cat')); 

それとも

$countchildren = count(get_term_children($term_id, 'product_cat')); 

それとも

$countchildren = count(get_term_children(get_queried_object()->term_id, get_queried_object()->taxonomy)); 

3が正常に動作しています。

しかし、使用しないでください。$taxonomyNameとして

$taxonomyName =get_query_var('product_cat'); 
$countchildren = count (get_term_children($term_id, $taxonomyName)); 

現実にあなたの主なカテゴリのスラッグではなく、分類スラグである：

$taxonomy = $queried_object->taxonomy;
