Re: Refreshing page after form submission

When you send out the FORM the first time, create a random unique value: $token = md5(uniqid()); Store that token in your database in a table. Include that in an INPUT TYPE=HIDDEN with a random unique VALUE="<?=$token?>" When you process the form, mark that $token in the database as "Submitted" If they attempt to re-process the same form (IE, the $token is already "Submitted") then you can do something, or nothing, or whatever you think best. > I have tried using cache control to no avail : Browsers and cache control have a turbulent history, and while they are really nifty for getting good browsers to refresh content, they are not real reliable. If you *need* more control over content caching, change your URLs, perhaps randomly, when you want content to not be cached. -- Like Music? http://l-i-e.com/artists.htm
