Detailed Description

If all of the fields specified in the otherFields list are not present in the input data, the field under validation must be present and not empty. For the other fields it will only be checked if they are not part of the input data, not their content.

If ValidatorRule::trimBefore() is set to true (the default), whitespaces will be removed from the beginning and the end of the input value before validation. So, fields that only contain whitespaces will be treated as empty.

See Validator for general usage of validators.
