Populate product options
 

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!

try {$smarty.get.key}

see smarty.php.net for more info

the {$smarty.get.key} I'm already using and it works great - outputs to the page - no problems

Would like to place this value in the product options field 'Custom ID'

Thanks
