That would be the idea, yes. It was some time since worked with Quick_Form, so there might be a specific order you need to perform the adding of the rule in relation to the validate() method call on the $form object. > Btw yes it must be checked when user submit this. But If it's possible > client option on rule, would be better. I am not sure about this, is there even client-side validation support in Quick_Form? Haven't really looked into this. I would suggest writing a manual javascript evaluation for the specific fields that should be visible when the checkbox is checked, or to have a postback between. The JavaScript option sounds most tempting, since it makes it a bit more user-friendly. That way you can use the JavaScript alert() function to present the fields that have erroneous information as well as altering styles in the fields in question to perhaps have a red border to indicate errors.
