T5 : How to compare old and new values of a form ?

[Webmaster Fée du Logis <we...@fee-du-logis.com>]

I would like to check if a value has been updated in a form before 
launching a time consuming treatment.
What's the simplest way to compare the old and new values of a form ?

Thanks in advance.

it depends how you store previous data,
... to do it all you'll need to look into form events
