I've worked this one out myself - and it was pretty obvious: use a beforeValidate method. I've included one below in case anyone else searches and needs the answer
/** * Returns true if all is ok, false if something failed validation */ function beforeValidate() { echo ''; // Sample code to invalidate one field and make validation fail $this->invalidate('field_Name', 'messageKey'); // messageKey can be the error message or the key to the error message in the messages array (see 1.2 validation documentation) return false; } On Mar 28, 9:18 pm, Tim W <[EMAIL PROTECTED]> wrote: > Hi all, > > Say I have a check box and a text field on a form.
