Jquery - How can I check if all of the checkboxes are checked?

pFor some reason my code doesn't work?! I need to check checkboxes, if all
are unchecked, then enable hidden field and send value to db, so I can
identify that checkboxes were unchecked./p pstrongQuestion 1:/strong Why
isn't my jquery code working?/p pstrongQuestion 2:/strong I need to record
checked or unchecked values to DB. My plan is to check if none selected in
php. Is this a good practice?/p pstrongHTML/strong/p precodelt;tr
