Display product counter only in subcategories - WooCommerce - php

Question

Hello stackoverflow community.
I am trying to get functionality to display a product counter but only in subcategories. In the main categories I want to disable it.
At the moment I have been able to do this:
function add_product_count_view()
{
global $wp_query;
$category_id = $wp_query->get_queried_object()->term_id;
$query = new WP_Query(array(
'tax_query' => array(
array(
'taxonomy' => 'product_cat',
'field' => 'id',
'terms' => $category_id,
'include_children' => true,
),
),
'nopaging' => true,
'fields' => 'ids',
));
if (function_exists("is_shop") && $category_id != 0) {
echo '(' .esc_html($query->post_count) . ')';
}
}
and output
<span class="custom-home-category-counts">
<?php do_action('count_product_title');?>
</span>
This way I got what I want but the counter shows the same value for each subcategory
----UPDATE---- #CBroe
It is possible that all this code is garbage. My knowledge of PHP is quite poor. Generally what I mean is, I want to disable the product counter in main categories and leave only in all subcategories.
This is the original code that renders the product counter.
<?php if (get_theme_mod('category_show_count', 1)) : ?>
<p class="is-xsmall uppercase count">
<?php if ($category->count > 0) {
echo apply_filters('woocommerce_subcategory_count_html', $category->count . ' ' . ($category->count > 1 ? __('Products', 'woocommerce') : __('Product', 'woocommerce')), $category);
}
?>
</p>
<?php endif; ?>

After every custom WP_Query, you need to run wp_reset_postdata() to ensure that global $post is restored to the current post in the main query.
In your code, you can use this function as follows:
function add_product_count_view()
{
global $wp_query;
$category_id = $wp_query->get_queried_object()->term_id;
$query = new WP_Query(array(
'tax_query' => array(
array(
'taxonomy' => 'product_cat',
'field' => 'id',
'terms' => $category_id,
'include_children' => true,
),
),
'nopaging' => true,
'fields' => 'ids',
));
if (function_exists("is_shop") && $category_id != 0) {
echo '(' .esc_html($query->post_count) . ')';
}
wp_reset_postdata(); //reset the main query loop
}
This way, the next time the query runs, it runs with new data. This can be the reason why the counter shows same value for all sub categories.
