The auto conf message doesn't support any 'logic' per se, only static text/html & {variables}.
A possible workaround (please use
, this workaround has been described before several times):
- adding a hidden field as a proxy container
- using my-functions.php / filter routine to populate the container based on any criteria (e.g. other form fields)
- in the auto conf message {reference} this proxy container
In v10.4 I will add additional application logic to my_cforms_logic() to allow to change the conf message on the fly.
This will make the proxy container unnecessary.
