web form script

I am looking for a script or code, so that when I fill out a form on one website it, automatically fills out a form on another website for me. ## Deliverables I am an independent contractor for a company. Recently the company came out with a 90-minute pre-recorded webinar that potential customers can watch online. At the end of the webinar the customers are given an opportunity to purchase. If they purchase, then I get a percentage of the sale. To automate and expand my marketing efforts I am developing an affiliate program, where I will share a percentage of the sale with people who refers visitors to the site and their visitor buys. In order to do this I need to have an affiliate management software in place, to track which affiliate referred what customer. I can't install the software on the website where the webinar is hosted. When a customer arrives at the website to watch the video they are asked to fill out a form with their first name, last name, and email address. Once they fill out the form they are taken to another page where they can view the video. This form populates a report that I get listing who viewed the webinar and who purchased the product at the end of the video by email address. If I have all the affiliates just drive traffic to the website, I have no way of determining which affiliate referred what customer and compensating the appropriate affiliate. However, at the same time I need the customer to go to the site through my affiliate link and fill out the form so I can get the commission when the customer buys. Then I would pay out the appropriate affiliate from my commission. My solution to the problem is to have my own domain and website so I can have an affiliate management software that tracks which affiliate refers what customer. However, I still need the form on the company website filled out so I can tell if the customer makes a purchase. I want to have a form on my website with first name, last name, email address. When a customer fills out that form the affiliate management software will have an email address to associate to the referring affiliate. Then I want some sort of script or code to automatically fill out the form on the companies website and submit it. I can then tell which affiliate referred what customer. I can tell when a visitor made a purchase. I can cross reference the two to compensate the appropriate affiliate.
