A multiple of total weight per order

I tried adding the following code to have a field (total_sauce) calculated from the total weight of each order:

add_filter(‘woe_get_order_product_value_total_sauce’, function ($value, $order, $item, $product,$item_meta) {

$value = $item[‘total_weight’]/8;
return $value;
}, 10, 5);

I already added the field and it’s showing up but the calculated value is not showing up.

we have to calculate total weight. So anyone who needs similar field

Please, follow to https://algolplus.freshdesk.com/support/solutions/articles/25000016635-add-calculated-field-for-order-
use meta key “total_sauce” and this PHP code.

add_filter('woe_get_order_value_total_sauce', function ($value, $order, $fieldname) {
	$total_weight = 0;
	foreach( $order->get_items() as $item_id => $product_item ){
		$quantity = $product_item->get_quantity(); // get quantity
		$product = $product_item->get_product(); // get the WC_Product object
		$product_weight = $product ? $product->get_weight() : 0; // get the product weight
		// Add the line item weight to the total weight calculation
		$total_weight += floatval( $product_weight) * $quantity ;
	}
	return $total_weight/8;
}, 10, 3);
