Hi,

You can use header('Location:someotherpage') to redirect the user to another page after they have posted. When they then press F5, they are on that new page without POST-data.

no, because is a page where a client put some orders, and he MUST see that page with the evolution of the orders
thanks

Yeah, but you can easily redirect to a php page:
header('Location:view_order.php");

function cleanPostVars(){
if (isset($HTTP_POST_VARS)) $HTTP_POST_VARS = array();
if (isset($_POST)) $_POST = array();
}

cleanPostVars();

But that is of no use as the $_POST data will still be sent when the user presses F5 to refresh the page!

tolgaong. I actually had to grin about your solution. :^D

Although it is what was asked for, you must have noticed that it isn't going to help out with the problem described.
