Hi there, love the plugin, love it!!

i have a multi form of 5, since not all of the fields are required so they  wont be checked for illegal entries (its potently unsafe if its save to database), can i run one function to check for all possibilities and make sure no illegal chars/nums.. etc, were entered.

and

function isValid($str) {
    return !preg_match('/[^A-Za-z0-9.#\\-$]/', $str);
}

// to validate

If i want to put it in to my_cforms_logic  function, how do i loop it thought all data – field names dynamically, and then set to return an error on the client form where the error was found?

Can any one help me please?
