Upload files in shopping cart using a jotform while associating the files to the order

I am trying to figure out a way I can include a jotform in my shopping cart that would allow my customers the ability to add the files associated with their order.

We use Netsuite as our website engine.

I know I can just add the embed code into my shopping cart page, but I'm trying to figure out a way the files can be associated with the order without the customer having to re-enter a bunch of contact information again.

Is there any way I can pull in the PO# or customer name into the jotform so when they upload the files I know which order the files are for? 

Attached is the from we use now which shows up after they checkout.

Hi,

I see that you already have a full system designed for a shopping cart. For the form, I believe you could just try passing values to the form via URL parameters.

Here are the possible guides that you can refer to:

From your list of products, you can then just pass the information from the product variable directly to the form's URL, so when do they a checkout the information is already prefilled:

If your website is built with PHP and Javascript, you can follow the guides below to pass information directly to your form:

You could also try checking this guide: http://www.jotform.com/help/126-How-to-send-Submissions-to-Your-MySQL-Database-Using-PHP. It's a guide on how to pass the values directly to your MySQL database, I believe if you are uploading files this would be helpful and would be easy to append additional values or characters to the file name to give distinctions like PO# or Unique IDs.

I hope that helps.

Thank you.
