I am integrating a payment gateway into a distributed wordpress plugin. The notification page (page that the gateway sends info to after the payment has been made) requires only a message of "success" or "fail" to be printed. In that page, I need access to the database and some org options. Can someone please tell me how to produce such a page (i.e. no menu, no header, no footer and etc.)? The gateway in question is alipay.
