Hey all,

I have a form, generated in php, with a lot of checkboxes on it. They
are initialized from the db. All checkboxes are in a 2d array and they
come through to my processing script fine. The only problem is that
the ones that are unchecked do not come through. I know that the post
command only sends the checked boxes. What I would like to know is which
ones were changed, ie checked or unchecked by the user. Right now I do
it by putting a string with the old values in a hidden textbox and 
comparing those to what I get back in the array. I have been thinking
about writing some client side script to produce the differences.

Does anyone know if there is a better way to do this?
