I solved my problem with: https://stackoverflow.com/questions/61622017/get-woocommerce-product-categories-that-contain-a-specific-product-brand/61624358#61624358 turns out wp_query wasn’t the right choice for my requirements.

Custom Field: how to save array of multiple key-values in WordPress
MySQL Query Returns Array () In Shortcode
Repeat a function with 24hrs gap for n number of days
The structure of the array you’ve provided suggests that you’re trying to access an incorrect level of the array. Try to replace: $t[0][“_give_amount”] = 25.00; $t[1][“_give_amount”] = 65.00; $t[2][“_give_amount”] = 100.00; $t[3][“_give_amount”] = 250.00; $t[4][“_give_amount”] = 650.00; with: $t[0][0][“_give_amount”] = 25.00; $t[0][1][“_give_amount”] = 65.00; $t[0][2][“_give_amount”] = 100.00; $t[0][3][“_give_amount”] = 250.00; $t[0][4][“_give_amount”] = 650.00;
How can I loop at a Specific Taxonomy from a custom post type?
<?php $totalprice_posts = get_posts(‘post_type=items&author=”.$thisauthorID.”&tag=’.$thispostID.’&numberposts=-1′); $totalprice_array = array(); foreach ($totalprice_posts as $post) { $productprice = get_post_meta($post->ID, “productprice”, true); $productquantity = get_post_meta($post->ID, “productquantity”, true); $totalproductprice = ($productprice * $productquantity); array_push($totalprice_array, $totalproductprice); } echo implode(‘,’, $totalprice_array); echo array_sum($totalprice_array); ?
Hmm…i might be getting you wrong, but do you know that WP comes with an AJAX callback framework that helps you with this, making calling your own callback file unneccessary?
I believe that your best option would be to create a single field and save all values in an array, something like this: Create more Meta Boxes as needed.
