Hi guys, am designing a seat reservation system. i want the check boxes to represent the seats

I want to know how to make each check boxes into array and how to group all the check boxes in a single canvas so that it will store multiple values in one single variable in the database column. there are other texboxes that i want to insert in the same form to get the use booking details.

If am gona store multiple value in one column how do i identify the check box group?
