The way to edit additional db table fields in CMS is to overwrite getCMSFields function. I want to fill some fields automaticly and disable them from editing by cms users. How can I make this? I see to solutions:

1) worse - in getCMSFields fill fields witah values, and disable them from editing in cms
2) better - catch save action called when button "save & publish" pressed and set fields

First solutions is quite easy to implement. But I've no idea how make second solution.

Thx for any help

this is not hard at all, try with overriding the $defaults array,

and specify the default values you need there.

then after that in the getCMSFileds method use headerfields
