Need some work for php ,mongo and some server side url redirection

Requirement: 1. simple html page with Signup button. ( [login to view URL] ) and Login button. 2. When clicked on signup button, it will goto “[login to view URL]” , which will have 4 fields : a. Full name b. Email c. Password d. Username and “Save” button. and When clicked on “login” button , it will goto [login to view URL] , which will have 2 fields a. Email b. Password and “Login” button. 3. When clicked on Signup - ->“Save” button , will send ajax request to php page . [login to view URL] 4. On [login to view URL] , on basis of “username” , we have to create new mongodb database. Note that we want to create different different databases as per “username” , which is going to be unique. so next time , any user logged in , we have to check its username in background , then points all requires to that database only. 5. Create “users” collection , inside “database “ and save signup info inside it. 6. Now from “[login to view URL]” page … we enter credentials , click on login button.. there is API , [login to view URL] a. which checks username from email id , b. check if any database available with that username c. if not give error , if yes.. and redirect to page [login to view URL] NOTE THAT: AFTER SUCCESSFUL LOGIN , THE URL SHOULD REPRESENT -> [login to view URL] format —> this is most important point .. you may have to play with “.htaccess” or “ if you can create subdomains .. [login to view URL] … this will also be fine.. note that , after login , on each with we want to track which username is … to KNOW … from database we have to select values.. Hope you understand this. Any doubt ask me.
