Detailed Description

If the other field specified as otherField contains any of the values defined in the otherValues list, the field under validation must be present and not empty. This validator is the opposite of ValidatorRequiredUnless.

Note

Unless validation is started with NoTrimming, 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.

Return type

On success, ValidatorReturnType::value will contain a QString.

otherField	Name of the other input field to validate.
otherValues	Values in the other field from which one must match the other field’s content to require the main field.
messages	Custom error messages if validation fails.

validate()

ValidatorReturnType ValidatorRequiredIf::validate ( Context * c, const ParamsMultiMap & params ) const
