I have added an extra
product option field called 'Custom ID' for each product.
The user customizes their product online and a unique number is generated.
I am able to display the unique number on screen with PHP.
How do I put/populate this unique number in to the product options field 'Custom ID'?
Example:
http://www.onlinestampandsign.com/product_02.php?productid=16134&cat=266&page=1&key= 02201742BC34L
Thanks greatly!
