in reply to Re: Re: passing an array to a checkbox_group
in thread passing an array to a checkbox_group

you have to pull the values from the checkbox with a param .. e.g.,
@fieldnames=$query->param('FieldNames')
and the resultant array is less tractable to splits and other parsing operations, so be prepared to use a substr() to separate out what you want.
