Question

I have multiple checkboxes on a web page. That is, I have 4 different categories of checkboxes. For example, I have those categories:

1. decoration
2. entertainment
3. catering
4. security.

Each of these have about 5 or more checkboxes.

How do I proceed to save them into a DB? I am using MySQL and JDBC.

Answer 1

I’d say make them attributes of whatever your form is representing in the database.

In plain English: make them BOOL values, in the same table that you’re saving to when the user presses the “Submit” button (or whatever you’re giving them in the servlet).

UPDATE

Okay, so if your users can only be one of each:

user_types
==========
ut_id        int pk auto_incr
ut_code      varchar(4)
ut_desc      varchar(127)

user_type_details
=================
ut_det_id    int pk auto_incr
ut_id        int fk references user_types
ut_det_code  varchar(4)
ut_det_desc  varchar(127)

Your entries would look something like this:

SELECT * FROM user_types;

ut_id    ut_code    ut_desc
=====    =======    =======
1        DECO       decoration
2        ENTR       entertainment
3        CATR       catering
4        SECR       security


SELECT * FROM user_type_details WHERE ut_id = 2;

ut_det_id   ut_id    ut_det_code   ut_det_desc
=========   =====    ===========   ===========
7           2        D.J.          dj
8           2        SNGR          singer
9           2        DNCR          dancer
10          2        GTRS          guitarist

And so on.
