NAME

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

VERSION

version 2.07

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" in HTML::FormFu::Role::Constraint::Others.

By default, if any of the named fields in "others" in HTML::FormFu::Role::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::Role::Constraint::Others, "attach_errors_to_others" in HTML::FormFu::Role::Constraint::Others or "attach_errors_to" in HTML::FormFu::Role::Constraint::Others.

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