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" 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.
