I need to set multiple fields as "required" in Channel Form/Zoo Visitor, but I can't find anything in the documentation that describes how to do this. I can't set the fields to be required in the CP because validation needs to happen at form level, not entry level.
None of the following works:
rules:field_1|field_2=“required" rules:field_1=“required"|field_2=“required" rules:field_1=“required" rules:field_2=“required"
Anyone got any ideas?
