RE: Re[2]: [PHP] Preventing a form from being submitted twice

Well, that's kinda hard to do. You should start by looking at the session management functions of PHP. Then, track your sessions by creating a table in a database. Then, once you are doing that...you will have a session id associated with any individual using your website. Once that individual submits an entry, save the session id with the order and don't allow them to submit another order since their session id is already stored. -OR- If you only want them to be able to submit ONE ORDER EVER, then create a cookie on their computer (that lasts for a year) once they have completed the transaction and check for the cookie every time someone tries to submit an order. IF the cookie exists, then prevent the order from processing. Hope this helps. -----Original Message----- From: rdkurth@starband.net [mailto:rdkurth@starband.net] Sent: Saturday, December 01, 2001 4:51 AM To: php-general Subject: Re[2]: [PHP] Preventing a form from being submitted twice could you give me a few more words to point me in the right direction Saturday, December 01, 2001, 1:41:49 AM, you wrote: Se> Two Words: Session Management >> How can I prevent somebody from using the back button after they fill >> in a form and it takes them to a second page that checks there data >> using php code.
