我已经编辑了woocommerce archive-product.php文件来实现我的布局，但还有一件事我需要弄清楚。我想在每页的档案中显示现有子类别的总数。
例如，我有两个主要产品类别（A，B），每个产品类别都有一些子类别：
SELECT * FROM (SELECT ROUND(CAST(val * CAST(0.01 AS NUMERIC(2,2)) / CAST(12 AS INT) AS DECIMAL(15, 9)), 9) AS val FROM [value] AS pr) a
我想显示每个父母的子类别的数量，在我的案例中，A档案页面中的2个子类别和B档案页面中的3个子类别。
这是我到目前为止所做的：
Category A
Subcategory A1
Subcategory A2
Category B
Subcategory B1
Subcategory B2
Subcategory B3
这是与我的问题相关的部分：

任何帮助都将不胜感激。
答案 0 :(得分：1)
您可以使用get_term_children()函数以这种方式计算子类别：
$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 ));
这3个工作正常。
但不要使用：
$taxonomyName =get_query_var( 'product_cat' ); $countchildren = count (get_term_children( $term_id, $taxonomyName ));
$taxonomyName实际上是您的主要类别slug ，但不是分类标记：$taxonomy = $queried_object->taxonomy;
