獲取每個WooCommerce父類別的現有子類別的總數

Question

我已編輯woocommerce archive-product.php文件以實現我的佈局，但仍有一件事需要弄清楚。我想顯示每個頁面中存檔的現有子類別的總數。

例如我有兩個主要產品類別（A，B）在它們中的每一個具有一定的亞類：

Category A 
    Subcategory A1 
    Subcategory A2 

Category B 
    Subcategory B1 
    Subcategory B2 
    Subcategory B3 

我要顯示的每個父的子類別的數，在我的情況2 A歸檔頁面中的子類別和B歸檔頁面中的3個子類別。

這是我迄今所做的：

這關係到我的問題的一部分：

<?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>'; 

        ?> 

任何幫助幫助將不勝感激。

Answer 1

您可以簡單地使用get_term_children()功能來獲取子類別數是這樣的：

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

或者

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

或者

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

三是工作的罰款。

但不要用：

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

由於$taxonomyName在現實中是你的主要類別塞，而不是分類蛞蝓是：

$taxonomy = $queried_object->taxonomy;
