I'm working on my first Zope project, an on-line photo galley, now located at http://localhost:8080/gallery/ . The image objects are stored in a subfolder called "imgs". The page at the above URL has a nav bar with links that have the id of the image object to display in a query string, like so: http://localhost:8080/gallery/?imgID=doorway. What I want to do is display below the image the title of the image object whose id is passed in the query string, sort of like a caption. For some reason, though, I can't figure out how to ask for the image object's title directly. What I'm doing now (and which works, but is ugly), is this:
<dtml-if imgID> <dtml-in expr="imgs.objectValues()"> <dtml-if "imgID==_['id']"> <IMG SRC="imgs/<dtml-var imgID>" width=<dtml-var width> height=<dtml-var height>> <P align="center"><dtml-var title></P> </dtml-if> </dtml-in> </dtml-if>
How do I just do something like <dtml-var expr="imgs.title_or_id(imgID)"> (or something like that) and make it work?
<dtml-var "imgs[imgID].title_or_id"> hth, Danny
TIA, Zope masters!
