Here's a fragment from a table that allows sorting by clicking the header
in a dtml method named 'displayTable':
Then feed sort_key into your SQLSelectQuery to use in an ORDER BY clause.
select * from table order by <dtml-var sort_key>
You can change the properties of an object in DTML by callling its
manage_changeProperties method, for example:
<dtml-call expr="foo.manage_changeProperties(bar='New Value')">
will changes the value of foo's bar property to 'New Value'.
There are several ways of getting the effect of assigning variables in
DTML, but it really isn't meant to have a direct way of declaring and
assigning variables. The way you're trying to use an object's properties
will, I believe, cause problems in the case of simultaneous users, because
it will act as a global variable.
