put
if (!isset($blocker))
{
your form goes here
within your form add
print "<input type=hidden name=blocker value=1>
end your form
}
With this, your input form is on the page when the page first loads (and
$blocker is not set), but disapears when the data is submitted and the page
reloads. Even if the user hits the refresh button on the browser, the
$blocker variable is still set and the form doesn't reapear.
You can chain up a bunch of these and accomplish with one page what would
have taken several.
Hope this helps,
Hugh
