ok, quick description of the problem, I'm trying to reference the postdata from some checkboxes. Unfortunately the checkboxes are dynamically generated therefore I don't know how many there are and thus can't name them individually.
I remember reading that naming them with square brackets (as "name[]") will automatically create an array in the postdata (meaning $_POST[name] is an array) is this true?
anyway, the fact is that my checkboxes are not posting. I print_r($_POST) and it comes back with all expected posts BUT not the checkbox postdata, even if I don't name them with [].
I will post code here for reference, but it's quite long.
