I'm designing an internal web application that uses MySQL as its backend database. The integrity of the data is crucial, so I am using the innoDB engine for its foreign key constraint features.

The serialize-string will be inserted in a mySQL-database, so it would be fine if all checkboxes would be inserted and not only the ones that is ticked(on). it's possible to make on column in the database for each of the checkboxes, and use this if/else-statement: if(isset($_GET['checkbox'])) {...
