note 67191 added to function.setcookie

You can use cookies to prevent a browser refresh repeating some action from a form post... (providing the client is cookie enabled!) //Flag up repeat actions (like credit card transaction, etc) if(count($_POST)>0) { $lastpost= isset($_COOKIE['lastpost']) ? $_COOKIE['lastpost'] : ''; if($lastpost!=md5(serialize($_POST))) { setcookie('lastpost', md5(serialize($_POST))); $_POST['_REPEATED']=0; } else { $_POST['_REPEATED']=1; } } //At this point, if $_POST['_REPEATED']==1, then the user //has hit the refresh button; so don't do any actions that you don't //want to repeat!
