Rewrite forms for custom module

[Chill_user]

Hello to all,

I have a questions about forms in BO (rewrite informations in custom module)

About my custom module:

1. I created a simple module which saves data in db tables - not the configuration values. (example)

2. All is working good exept I don't know how to  modify the existing data in db.

Exactly the questions:

- how to create forms to edit the data in the db from backoffice module?

 I tried to create form template in mymodule/templates/admin/custompage.tpl , the code is working but info is not editiong.  Also I tried to create forms with formhelper with custom functions.

How can I create a page, where I can edit db values?

 

Thanks a lot!
