I'm building a site which catalog (products) are shown and when clicked a Adobe Livecycle generated pdf will be opened. There are few form fields and when the submit button is pressed, the fileds will get submitted to the url http://localhost:3000/pdf-parser. This file will get all the parameters and can store in the database. The problem is to identify which user is sending the data via Pdf? This could be accomplished if I could inject some parameter like user_id into the Livecycle pdf file which would get passsed to the http://localhost:3000/pdf-parser so that I can stamp the user. I googled for this serveral times but I couldn't get the answer to this as Adobe Livecycle is a new product. So, can ayone-rails coder point me to the right direction?? Or is this even achievable?? Or is there any other solution to this problem??
