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/
