You cannot redirect the user with a form post also since a redirect is simply a header telling the browser that the page has moved. You could however hack something up with a quick intermediate page with something like this:
function post_redirect($target, $post_vars)
{
echo "<form action=\"$target\" name=post_form method=post>";
foreach($post_vars as $name=>$value)
{
echo "<input type=hidden name=\"$name\" value=\"".htmlspecialchars($value)."\">";
}
echo "</form>";
echo "<script language=javascript>document.post_form.submit()</script>";
}
