Class: HTML_QuickForm_advcheckbox  - X-Ref

HTML class for an advanced checkbox type field

Basically this fixes a problem that HTML has had
where checkboxes can only pass a single value (the
value of the checkbox when checked).  A value for when
the checkbox is not checked cannot be passed, and
furthermore the checkbox variable doesn't even exist if
the checkbox was submitted unchecked.

It works by prepending a hidden field with the same name and
another "unchecked" value to the checbox. If the checkbox is
checked, PHP overwrites the value of the hidden field with
its value.

__construct($elementName=null, $elementLabel=null, $text=null, $attributes=null, $values=null)   X-Ref
