It has been my idea to make a function, and pass the fields, then register a global
feedback var
and then check one by one each required field, or what ever you are trying to verify
in the
fields.
function formCheck ($username,$password,$smellycat) {
global $feedback, $username, $password;
if (!$username) {
$feedback .= "Yo! This ain't right ... fix it!";
return false;
}
blah blah blah ...
