You don't use the cgi module when using the mod_python publisher
handler. Your function will be called with the form variables as named
parameters, like this:
def handle_form_input( req, firstname, lastname ):
# do something here
I would recommend giving defaults for the parameters so if the user
doesn't submit a value it, it doesn't throw an exception, like this:
def handle_form_input( req, firstname=None, lastname=None ):
# whatever
And, I've been known to simulate the cgi behavior like this:
def handler_form_input( req, **form ):
# access your form variables as an array
print "You entered %s %s" % ( form[lastname], form[firstname] )
But, remember that this "form" is a simple dict, not a cgi.FieldStorage
and I don't know what it does with multiple values with the same key.
FieldStorage puts them in an array, you'd have to experiment with this
in the publisher handler.
See how much better answers you get when you ask good questions and
include error messages. :-)
Hope that helps,
