RE: [Zope] How to use RESPONSE.redirect ?
Thanks for the input. I ended up putting the info I needed into the url
dtml-var "someurl?a=blah"
I put it in a method that is usuble from a couple of forms and it seems to
work.
Thanks again.

Hi Stuart,
i ran into the same problem a little while ago. i was trying to pass the
user around to the proper displayprocess page(with inputs inplace)
after a logic page that determined where they should go based on their
inputs. IMO, The crux of the problem is that Zope as a web development
platform should include the urlparse lib from the python core more over
this problem and others like it should be remedied i believe by a
standard method of extending the modules in the _ namespace with thread
safe modules that a developer deems nesc. OK enough soap box... i ended
up reimplementing the nesc. functionality in a python method and created
another method to implement complete form insertion in much the same the
style that of some ACS(arsdigita) utiltiy methods do. here they are,
usage examples are included in the code.
of course this solution requires evan simpson's python methods product
be installed on your zope.
Cheers Kapil

If you want to pass the form variables, you're in for a fight. (o8
otherwise, you could simply try :
dtml-var "otherform(_.None, _)" instead of a redirect.
If you want to make sure only the correct form vars are passed, you could
flub it with something like:
dtml-call "RESPONSE.redirect('otherform?var1=%svar2=%s' % (var1, var2) )"
If this doesn't help, some more detail on your part might. (o8
Any ideas..
TIA

Have a better one,

If your original form submits using the GET method, then QUERY_STRING
will contain the already URL encoded parameters that the browser
sent originally.
True. However, the GET method is of limited utility which is not
appropiate for many situations mainly because of size constraints.
Examples, file upload, most anything with text area, stuff with a user
passwd. Granted the above example is something that is going to stick
the whole thing in the URL anyways. But the two python methods can be
used for both GETs and POSTs and if you use the second method
url_encode_vars you can pass it a dict of only those values you want to
receive in the next page example.
dtml-call "RESPONSE.redirect(url_encode_vars({'var1':var1,
'metoo':metoo}))"
DTML also has a url_encode format you can use to cause a string to
be url encoded if it isn't already. Check the dtml reference.
been there, done that.
DTML fmts are useful only for inserting text into a page or link with a
dtml-var or the entity syntax. there are no functions that will
encode a var in a pythonish expression("") which is what you need when
doing this with a redirect.

Re: [Zope] How to use RESPONSE.redirect ?
HTTP is stateless. You'll have to build the entire query string and put it into
your redirect URL.
