You can write a function and when using it in a script insert
$HTTP_POST_VARS as the argument:
function filled_out($form_vars) {
foreach ($form_vars as $key => $value) {
if (!isset($key) || ($value == "")) {
return false;
}
}
return true;
}
(I think this is from the Welling and Thomson book -- PHP and MySQL Web
Development.)
