Simple Database Script

We are using a website called [login to view URL] to sell a software product. This script will be called automatically from that above website after a purchase is made. It sends (via http post) a list of details (username, password, email address, receipt, etc). We require all this information to be recorded in a mysql database. The program will then send an email automatically to a given email address with the contents we specify (connect to an auto responder). Then page will then redirect to another standard webpage. In additional another part of the script called from another page. This script will read a table and have another table to keep track of which record it previously read. If it gets to the last record on file it goes back to the first one. It will take a field from that table and join it with other fixed data we will provide you to form a url. It will then increment the variable pointing to the last record read so the next visitor using the script retrieves the next record, etc. The script should then automatically redirect to that url. This is a very easy script for an experienced php code who knows mysql. We will provide more extensive details to the successful bidder
