Hey people, I just wondering how i would go about updating a item_quantity field in mysql database. This is the dilemma:

im building a site that allows people to sell there own items abit like ebay does, they will provide details of there item into a form that then gets entered into my database, they will have a paypal button that will pay into there paypal account once the item is sold, but im trying to figure out how can i update my database once their item has sold to update the quantity field.

please any ideas would be great??

iv been looking throu the scripts available and even searched the paypal site but im getting the impression that i have to set MY paypal account ipn settings to allow the ipn script to work BUT paypal wont be accessing my paypal account. There doesnt seem to be any good examples even on youtube

when the seller comes to my site to sell something a paypal button will be dynamically made for each item they are selling then once the item has sold i want to be able to update my database to either reduce the qty or set a field to sold so the item doesnt display anymore.

any help or idea appiciated or if anyone knows how to do it i can pay
