Hi guys,
I know I've seen this answer before when browsing the forums - but I've search all day and I cant find it. How do I do a callback function to check another field?
i.e.
Field A
Field B
$this->form_validation->set_rules('fieldb','FieldB','callback_field_a_check');
Then in the callback, apply a rule to Field B, depending on what is in Field A?
I.e. Field B is ONLY "RequireD" if Field A is used
