[pmwiki-users] how to re-show form with pre-existing field data?

[Shi Sherebrin]

hi,

I'm using ZAP forms to submit data from a survey.

There are some required fields, and when they are left blank, the form is 
re-displayed with a "data missing" message.  However, when this happens all the 
other forms that *were* filled out come back blank.  Apparently this is 
something that should be solvable at the PmWiki level.  I'd welcome ideas for 
how to do this.

here is my current source code:

(:messages:)
(:zapform:)
(:zap ip={$IPAddress}:)
||width=80%
||'''Email address:''' ||(:input text e_mail size=30:) ||
||'''Name:''' ||(:input text name size=15:) ||

(:zap required="e_mail,name":)
(:zap savedata="ip,e_mail,name":)
(:input submit value="Submit":)

(:zap nextpage="Test.Done":)
(:zapend:)

thanks,
Shi.
