product packaging is a default feature of Virtuemart, no plugin is used.
For a Google Merchant Feed i need the product_unit column from the virtuemart_products table. It's for the unit_pricing_base_measure tag described on https://support.google.com/merchants/answer/7052112?hl=en
For a second comparison shopping website i need the final price (with vat) divided with product_packaging from the virtuemart_products table and the product_unit information from the same table as a string.
$needed = $product->product_price_with_vat / $product->product_packaging . " " . $currency . " / " . $product->product_unit
Is it posible to use more than 6 user extended fields in the professional version of productXport? I run out of these fields if your solution needs this feature.
