[Zope] Composing variables

[Jonathan]

I don't know if this is what you are looking for, but can use a form of indirection that is available thru dtml:

<dtml-call "REQUEST.set('a1', 'aaa')">
<dtml-call "REQUEST.set('b1', 'a1')">

<dtml-var b1>
<br>
<dtml-var "_[b1]">

will print:

a1 
aaa 

This will allow you to load variable b1 within a 'pointer' to a variable containing the data you want.

  Hello Andreas and thank for your answer. I've posted this question to at-users
  list too but still no answer. In fact this problem is not related only to AT. Let me 
  give you an example:

  var alternative = 'bar' or 'baz'
  var foo_baz = 'content based on baz'
  var foo_bar = 'content based on bar'

  These can be defined either in ZPT, DTML or Python Script. The problem is the same.
  The question is how can I obtain the value of foo_$alternative.

  An example written in PHP:

  $alternative  = "bar";
  $foo_bar = "content based on bar";
  echo ${"foo_".$alternative} 

  This will produce "content based on bar".

  Thanks for your time,
  Cristi

    Please ask AT related questions on the at-users list. In general you should 
    not access attributes in AT directly but only through the accessor methods.
    There is something like getField(fieldname) in the AT which might help you
    (look also at the AT docs).
