Thanks Vsourz, let me explain myself better:
I’m adding into body mail the special mail tag [_serial_number] like this:
Your ID: [_serial_number]
This is working just fine (I’m getting an email confirmation with an incremental number for each submission). Nevertheless, what I need is to include that [serial_number] value into Advanced Contact form 7 database.
I tried with dynamic hidden plugin but is not working… Is there any possible solution for this?
