Hi; Here's my code. I know there are all sorts of errors. But I'm not sure where in the documentation to find the corrections (other than somewhere in the Zope Book). Your help would be appreciated.
<dtml-let lang="REQUEST.get('HTTP_ACCEPT_LANGUAGE')"> <dtml-in expr="context.objectsInTheFolder"> <dtml-if expr="&dtml-id==&dtml-lang"> <dtml-let approved="&dtml-lang"> <dtml-else> <dtml-let approved="en-us"> </dtml-if> </dtml-in> </dtml-let>
First of all, terminate all &dtml entities by a semicolon. Second, dtml-let needs a closing tag. This tag can't be outside of the DTML hierarchy the opening tag is in, which means that if you define a variable inside of a dtml-if, you have to close it inside, too, and the value is lost for further use. Shortly: this won't work, try another way. Third, IMHO it doesn't make sense to extract values from variables inside a Python expression per DTML entities, try "id == lang" in line 3, and correct line 4 accordingly (your DTML namespace will be correctly looked up inside the expressions, you don't need the &dtml-...; part). Point four: would it be possible that this could be better done in a script? Good night! Martin
