HTML form submissions will not send you information about
unselected
form items. So either you need a way to regenerate the list
from
scratch, or you need to include the ids in a hidden field in
the form
itself.
In the latter case, make sure to somehow protect the list of
ids so that
they cannot be tampered with by the form submitter -- who
could
otherwise just add extra ids to the list and cause
potentially unwanted
deletions. One way to do this would be to include a hash of
the id
values plus a secret key. Or encrypt the id list with some
form of
symmetrical encryption.
