HTML::FormFu::Constraint::DependOn(3p)

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

SYNOPSIS
    type: DependOn
    name: foo
    others: bar

DESCRIPTION
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".

By default, if any of the named fields in "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", "attach_errors_to_others" or "attach_errors_to".

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