[mastrboy]

is there a bether way to do this?
(checking for empty variables..)

function validateEmpty($theinput,$description = '') {
                if (empty($theinput)) {
                        $this->errors[] = $description;
                        return false;
                } else {
                        return true;
                }
        }

That looks to be about the simplest way. Why would it need to be any simpler if it works? 🙂

Nothing, injections normally occur when peope use eval or by putting unescaped, unprocessed strings directly into a MySQL query. If your looking toi avoid exploits you'll need things like addslashes etc.
