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.

SEE ALSO

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