Thanks Chris, Chris and Quentin! But contrary to my earlier findings, it turns out the session var is not staying in memory.... Does this mean I haven't got the necessary part of Zope installed? The session item first comes up as follows: SESSION id: 10309401531156298065, token: 42527132A0c0Y8rr7Ag, contents: [('TrolleyQty', '1'), ('TrolleyStockNo', '4')] but when I move to another form and view the request there, the session now reads: SESSION <Python Method object at 0x86292d0> actually, the session appears under "lazy items" the second time around, do I have to refresh it or something every time? in which case I could just re-store the REQUEST var every time, but this seems a lot of hassle to do this on every form!! or is it still there and I'm just not reading it properly? I cannot get the list function to work! but maybe sorting this out will sort that out as well.... so have I just got something switched off I can switch on? thanks all! Regards, Greg.

See also http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/Sessions.stx for exhaustive sessioning docs. These are written for 2.6 but mostly work under 2.5.

Would have actually been better to do this with the python script:
request = container.REQUEST session = request.SESSION
stockno = session['StockNo'] stockno.append(request['TrolleyStockNo']) session.set('StockNo:list', stockno)
qty = session['Qty'] qty.append(request['TrolleyQty']) session.set('Qty:list', qty)

You'll have to get the list, add the item, and then put it back:
<dtml-call "REQUEST.SESSION.set('StockNo:list',REQUEST.SESSION['StockNo'] + [TrolleyStockNo])"> <dtml-call "REQUEST.SESSION.set('Qty:list',REQUEST.SESSION['Qty'] + [TrolleyQty])">
Ugh it's about time to make that in a Python script:
request = container.REQUEST session = request.SESSION
stockno = session['StockNo'] + [request['TrolleyStockNo']] session.set('StockNo:list', stockno)
qty = session['Qty'] + ['TrolleyQty'] session.set('Qty:list', qty)
Aah, much more readable :)

Hi Quentin,
That does indeed help, many thanks!
Except... how do I get the variables to add themselves to each in a list fashion?
I expected this to work....
<dtml-call "REQUEST.SESSION.set('StockNo:list',TrolleyStockNo)"> <dtml-call "REQUEST.SESSION.set('Qty:list',TrolleyQty)">
...but instead got some variables called StockNo:list and Qty:list who's values were replaced by every interation, not added to!
Regards,
Greg.

Hi- Most new Zope installs come with a session manager in the root folder, and a temporary folder with a session data container. All you have to do is use REQUEST.SESSION.set() instead of REQUEST.set(). HTH, --Quentin On Sunday, September 1, 2002, at 10:59 PM, Greg Conway wrote:
Hi all,
Just wondering, does Zope (I'm using 2.5.0) have built-in session support?
I have just discovered that my REQUEST variables don't stay in memory! so I just need something that will store a variable in memory regardless of traversing through forms!
I guess that this means sessions sessions or cookies, not really sure about either of them, and preliminary findings indicate I may need to add more stuff into Zope to get sessions working!
So if there is any easy way of doing this, can somebody please enlighten me before I go off at a lengthy tangent again to re-invent the wheel?
:)
many thanks!

Greg Conway.
