I think the simplest way to handle this would be to process all available
options each time that form is submitted. Create a hashtable (or the PHP
equivalent - it's not my strongest language, sorry) with every option's
value set to false by default, compare it with the form array and update all
submitted values to true. Then update each corresponding field in your
datastore to true or false accordingly. A little more work for the db, sure
- but spares you the headache of trying to trap the nebulous "unselect"
