I apologize for the (probably FAQ) newbie problem. FedEx hasn't delivered my copy of "The Zope Book" or "Programming Python" yet, so please forgive me.
Suppose I have the name of an object in variable `foo'. I would like to test for the existence of the named object. Suppose that foo=='bar'. The following won't work:
<dtml-if foo> <br>Yep! </dtml-if>
because `foo' will always have a value. How, then, can I see if `bar' exists?
A million thanks,
try: <dtml-if expr="_.has_key(foo)"> there is an object named <dtml-var name="foo">! </dtml-if> hth, /---------------------------------------------------\ Casey Duncan, Sr. Web Developer National Legal Aid and Defender Association c.duncan@nlada.org \---------------------------------------------------/
