PHP coding with AJAX

I require a function to be written that mimics the same function on another facebook application. This function is found at [login to view URL] I want to duplicate the Send Gifts function and the way it works. I will add the gifts to the database and setup the categories. The send gifts function should automatically pull the categories and gifts from the database. I also want the same function created for posting messages on the walls. Both functions should exactly mimic the ones given in the link above. I will provide FTP and database access, and advise which files the code should go into.
