Re: [Zope] Simple Problem (SESSION)

6 Aug 2002

      What Zope version are you using? You will need to have a Browser ID
Manager and a Session Data Manager somewhere in the tree where the DTML
document can acquire them (may as well be the root directory). If they
aren't there, add them, using the default options. You'll also need a
Session Data Container; this is best placed inside the temp_folder
created by default on installation. You'll need to point the session
data manager to the location of the session data container. 

Some or all of this structure is created automatically on installation;
I can't remember precisely how much. Anyway, add in anything that isn't
there, and sessioning should work.

This seems to work:
<dtml-var standard_html_header>
<dtml-unless "REQUEST.SESSION.has_key('foo')">
<dtml-call "REQUEST.SESSION.set('foo',0)">
</dtml-unless>
<dtml-call "REQUEST.SESSION.set('foo', REQUEST.SESSION['foo']+1)">
<h2><dtml-var title_or_id></h2>
<p>
You have visited this page <dtml-var "REQUEST.SESSION['foo']"> times.
</p>
<dtml-var standard_html_footer>
(The attributes of SESSION are listed in the API Reference under
TransientObject (of which it is an instance). But it behaves more or
less as a dictionary.)

Hi,
How can I make a page, in Zope, that when it is opened in print "1" and
every time the user refresh the page the number increments itself (2, 3,
...), using SESSION?
Thanks in advance,
Rares
