Ecommerce digital product payment database PHP. I have a learning program on the web made in FLASH that helps people learn At the moment I do not have a website and no way to accept payment at this point. Within the FLASH software I have a simple database where I can add users to login into the software but I want to take this to the next step. I want to be able to have an database to add users and delete users automatically after payment is received and have a set amount of weeks of usage. 1. User view website and decides to pay for 1 month usage. ( 7days, 1, 6 12 months usage can be bought ) 2. User inputs details into the website, name, suername, address, username, password, email etc. 3. Once payment is received ( paypal) the system will send an invoice email to user. 4. The database will automatically add the user name and password from the details inputted from the user. 5. User will be able to use the service for period paid and system will send a reminder when period is over. So what is needed: A simple website to show what the service is about. All designs, text and pictures will be supplied The ability to do all 1 – 6 points.
