Class Summary HTML_QuickForm_advcheckbox
Описание
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 creating a hidden field with the passed-in name and creating the checkbox with no name, but with a javascript onclick which sets the value of the hidden field.
