[RESOLVED] Stop a page from being 'refreshed'

[stewartship]

Hi everyone.

Does anyone know how to stop a page from being refreshed. The scenario is the page is using sessions and user input, once all is validated, a query inserts the information about the order and designates an order_id (primary key, autoincrement on a mysql table in my databse), and the information is shown on screen. the problem is, that each client can technically have multiple orders, but i have a seperate section to deal with this.

SO what i need is some info on how to stop a user being able to use the refresh button on their browser toolbar, which posts the page again creating another order and order id for that client, which i dont want!

Thanks in advance for your help.

PHP can't give you that sort of control over the client-side software and I doubt that JavaScript could either. That sort of control is potentially quite dangerous.

One possibility would be a confirmation mechanism. Or, since you're already writing a stateful application, you could add a facility to make it able to distinguish between a mere page refresh and a new order submission.

Hi saraadmin!
Thanks for the quick response. I agree it does seem a bit dodgy. Thanks for the advice think i will try and use one of the session order_id variables as a control, gonna be a bit fiddly but should work.
Thanks
