[Zope] Returning a ZPT form with fields filled in

[robert rottermann]

I give you here an example how you can do it as a set of a pagetemplate 
and an acociated script.
How to adapt it to your partiqular situation is up to you.
Robert

here a minimal form with one field:
As you can see values are collected first from the request.
They are put there when pass parameter trough the url like so:
http://myserver/mytemplate?first=robert&last=rottermann
if it they are not found not found there then the options are checked.
The parameters are put there when you call the template as a method in a 
python script like so:
return mytemplate(first="robert", last="rottermann")
If neither of them yield a result nothing (which is an empty string in 
this situation) is assigned.
The net result is, when you call the template the first time, an empty 
form is presented,
when you press the submit butten the form is represented with its input 
converted to lowercase.

<form action="myscript" "tal:define="
    name request/first | options/first | nothing;
    age request/last | options/last | nothing;">
       
    <input name="first" type="text" tal:attributes="value first">
    <input name="first" type="text" tal:attributes="value first">
    <input type=submit">
</form>

Here the script myscript

## Script (Python) "myscript"
##bind container=container
##bind context=context
##bind namespace=
##bind script=script
##bind subpath=traverse_subpath
##parameters=frst, last
##title=
##
# do some processing
first = first.lower()
last = last.lower()

# call the page tamplate as function and pass parameters
return mytemplate(first=first, last=last)
