Maybe someone else will correct me, but I think one way to do this is indeed
to write your own validator. When you add the validator you might say
something like
'multi_fields'=>array(
new My_Validator_OneOrMoreFields(),
'fields'=>array('phone','email'),
'messages'=>array("Please provide either a phone number or an email
address')
),
And in your validator's logic you check that either one or the other is
nonempty. Meanwhile you can also add the validators e.,g., on the email,
that ship with ZF, with the allowEmpty flag set to true.
I did this for one form, and found I could use it again for another, giving
me a pleasing sense of DRY satisfaction.
