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 HTML::FormFu
