Update product_quantity with -1 turns out unlimited

-- HikaShop version -- : 2.6.4

Dear support,

We encounter that when we import csv file to update product_quantity
(with 'Update the product quantity instead of replacing it' turns on),
product quantity become unlimited instead of deduct 1 from current product quantity.

Is this a bug or we have another solution to have this problem solve?

Thank you

Hi,

Mmm well it's not really a bug. This allows to you update the quantity to unlimited as -1 means unlimited in HikaShop.
The problem is that you can't decrease the quantity with the 'Update the product quantity instead of replacing it' option turned on.
If you want to change that, you can replace the line:
if(JRequest::getInt('update_product_quantity','0') && $field=='product_quantity' && $product->product_quantity != -1){
to:
if(JRequest::getInt('update_product_quantity','0') && $field=='product_quantity'){
