HTML::FormFu::Constraint::DependOn(3pm) User Contributed Perl Documentation HTML::FormFu::Constraint::DependOn(3pm)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::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.
