Display total sales for category in WooCommerce - php

Question

I'm trying to list the total amount of product sold at the top of each category page.
A portion of this total will be donated and my client wants to advertise the amount. I have been looking and trying things for hours now and have not had any luck. I found a plugin that displays total sales for the whole store, but I want just one category.
I tried adding another filter to this plugin, but no luck. Any thoughts?

Answer 1

function getSaleAmountbyCategoryID($product_cat_id)
{
//first getting all the Product ID by Category ID
$pro_args = [
'post_type' => 'product',
'pages_per_post' => -1,
'post_status' => 'publish',
'fields' => 'ids',
'tax_query' => [
[
'taxonomy' => 'product_cat',
'field' => 'term_id', //This is optional, as it defaults to 'term_id'
'terms' => $product_cat_id, //(int)
]
]
];
$product_ids_query = new WP_Query($pro_args);
$include_product_id = $product_ids_query->posts;
//getting all the success orders
$args = [
'post_type' => 'shop_order',
'posts_per_page' => '-1',
'post_status' => ['wc-processing', 'wc-completed', 'wc-onhold']
];
$my_query = new WP_Query($args);
$total = 0;
$orders = $my_query->posts;
foreach ($orders as $ctr => $value)
{
$order_id = $value->ID;
//getting order object
$order = wc_get_order($order_id);
$items = $order->get_items();
foreach ($items as $item_data)
{
$product_id = $item_data['item_meta']['_product_id'][0];
if (in_array($product_id, $include_product_id))
{
//getting product object
//$_product = wc_get_product($product_id);
//$qty = $item_data['item_meta']['_qty'][0];
$pro_price = $item_data['item_meta']['_line_total'][0];
$total += $pro_price;
}
}
}
return $total;
}
Add the ^^above code to your active theme functions.php
USAGE
In your product category page template call it like
echo getSaleAmountbyCategoryID(21); //replace it by your product caregory ID
Please Note: I won't say this is a best solution as it will be slow if you have 1000s of order. If I find out the better solution I'll update my answer.
Hope this helps!
