[Zope] dtml sessions?

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.
