Convert PHP multi page sign up to session

Current multi page account signup form complete in php and inserts into MySQL database. Need to convert to a session with login and password assignment. **New Features to be incorporated:** * Capture billing info to pass through to a cgi for credit card processing. * Once login/password has been selected/inserted into DB, rest of sign up form is available for future editing. Login will always be email address. * Login/Authtenticate/set cookie for session. Reset password class to generate a random password for reset needed. * The code must be in PHP with insert into MySQL DB. Commented code required for any functions used. Developer will be provided current PHP pages and Database schema. Work to be done on developer's server, with a working version to be available for review on the developer's server. Work will be accepted when user can 1. Enter an account user/password (a check must be made to eliminate multiple accounts with same email address) 2. Sign In/Out of account. 3. Edit any part of sign up form once logged in, and have those changes saved to db with a timestamp. (The timestamp will only apply to certain records, not all) 4. Upon user billing entry, code will display labled variables and data for pass through to credit card processing. 5. Code will display pass back variables (accepted/rejected) from credit card authorization. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Exclusive and complete copyrights to all work purchased.
