Codeigniter, MySQL Job by wherewhyhow

Here’s what I need doing: My website allows people to post listings once they have signed up, so there are currently two databases: Users: - Email address: - Password Sitters (listings) - First name - Last name - Address fields - Postcode - Description of services - Cost (rate) - Sitter photos I want to change this so that the users database can be completed by connecting to Facebook. So when a user connects via Facebook it will pull in the email address, first name and last name, and the profile picture photo. The system should check whether the user’s email is already on the system first. The database scheme may need to be slightly changed to look more like this: Users: - Email address - Password / (or Facebook ID) - First Name - Last Name - User Photo Sitters - Address fields - Postcode - Description of services - Cost (rate) - Sitter Photos What I want has been implemented by a couple of websites, such as Vayable ([login to view URL] ) [login to view URL] and www.dogvacay.com. Please don’t worry at all about what the site looks like – I can do this myself. Hopefully this helps you get started. If you need any more details or have any questions I am happy to provide more details.
