HTML::FormFu::Constraint::DependOn - Multi-field Dependency Constraint

    type: DependOn
    name: foo
    others: bar

If a value is submitted for the field this constraint is attached to, then a value must also be submitted for all fields named in others in HTML::FormFu::Constraint::_others.

By default, if any of the named fields in others in HTML::FormFu::Constraint::_others are missing, an error will be attached to each missing field. This behaviour can be changed by setting any of attach_errors_to_base in HTML::FormFu::Constraint::_others, attach_errors_to_others in HTML::FormFu::Constraint::_others or attach_errors_to in HTML::FormFu::Constraint::_others.

This constraint doesn't honour the not() value.

Is a sub-class of, and inherits methods from HTML::FormFu::Constraint::_others, HTML::FormFu::Constraint
