Hi Ian, Here are a few ideas regarding this.
Best deal with session variables within a CFLOCK statement (see docs for
details of possible race conditions) and therefore a useful way to go about
this is to copy any session structures to the request scope on each request.
I have a similar 'wizard' style process and I create a structure (inside
cflock) session.wizard
For each wizard step I create session.wizard.stepN (where N is step
number).
I then duplicate this structure to the request scope so that I can forget
about locking from now on.
In each form page I CFPARAM request.wizard.stepN.formfieldN for all my form
fields for this step with any default values.
When the form is submitted I cfloop thru the form structure and copy the
form values to the request.wizard.stepN.formfieldN values. Finally I
duplicate the request scope to the session scope inside a CFLOCK so the
values are remembered to the next request.
In terms of keeping this data in some way, you might consider using CFWDDX
which can convert complex CFML variables (like your wizard structure) and
convert them to a XML string. You could then write this string to a file or
database. CFWDDX can then be used to convert it back again. There are many
ways to store this data but this in my mind would be the neatest.
