.SH DESCRIPTION
.IX Header "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.
.PP
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.
.PP
This constraint doesn't honour the \f(CWnot()\fR value.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
Is a sub-class of, and inherits methods from
HTML::FormFu::Role::Constraint::Others, HTML::FormFu::Constraint
