From this link: http://gerhardpotgieter.com/2013/09/17/woocommerce-custom-product-fields/
they have explained how to add custom product fields, BUT I didnt understood in that code for which specific product…
I mean for which product page, they’re adding custom field?
To be more clear, where to add my product id in that code so that my custom fields would appear in my required product page..
Sorry, if its a dummb question. ( iam not good at php ). pls understand.
