[Zope] dtml-in and if

[Phil Harris]

James,

Create a Script(Python) called news_filter that has these contents:

#---start of the filter
retval=3D[]
for a in objectValues(['Informatie', 'sitenieuws']):
    if has_key(a.aq_explicit,'publish'):
        retval.append(a)
return retval
#---end of filter


then in your dtml method:

<dtml-in news_filter start=3Dquery_start size=3D"6"
sort=3Dbobobase_modification_time reverse>
  <dtml-var title>
</dtml-in>

caveat: all this is untested as it's written, but should give you some
ideas.

Phil
