Just check the value in db_operation.php. It looks like you have the skills. If not, let us know.

Browsers don't send checkbox data if the checkbox is not checked. You will need to find another way to obtain the data. One way is to have it already on the server. Hidden inputs is another way.

Yes, but you can always check if the key has been set.

Yes, that's supposing it has a unique key, you can use isset().
