I am looking for a programmer to build an AJAX-based product reviews module. - Save user ratings and comments in a single record - No page refresh (XMLHTTP) - Hovering star ratings (as on Youtube) - User may only rate a product once (I already have the registration / authentication system) - Display comments and stars - Average star calculation I know how to program using PHP and MySQL so I will provide all database fields and variables. I just need help with the Javascript. Please feel...
