RE: [PHP] Re: How to unset a post variable

Your best bet is to check that the data has not already been inserted rather than try to fiddle with the post: Don't know what db you are using but something like IF NOT EXISTS (SELECT X FROM Y WHERE Z=1) INSERT INTO Y VALUES X Cheers Mark -----Original Message----- From: Nieko Maatjes [mailto:php-news@nieko.net] Sent: 15 April 2005 14:34 To: php-general@lists.php.net Subject: [PHP] Re: How to unset a post variable On Fri, 15 Apr 2005 14:08:36 +0200, Mario de Frutos Dieguez <marfru@cartif.es> wrote: > My question is, how can i unset $_POST["buttonNew"] or leave it empty > because when the user refresh the page make insert commans again because > the $_POST["buttonNew"] arent empty. The browser sends $_POST, you can't just tell PHP to accept it the one time, and not the other, unless you use sessions of course. You might also try to refresh using a "302"-header I think, but I forgot how it worked exactly. It makes the browser refresh so that next time the user presses F5 or something the POST-data doesn't get sent. -- Nieko Maatjes http://www.nieko.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php Gamma Global : Suppliers of IBM, Compaq, Cisco, Sun Microsystems, 3Com and HP Products.
