Thanks for the reference to the DTML Guide...it has helped a lot. I have come across something that I couldn't seem to find an answer to. I have the following line in my original code that I uploaded from an existing HTML directory...I can't seem to find a dtml tag that will replace the echo statements here...
href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80/ <!--#echo var="><!--#echo var="REQUEST_URI" -->;weblint"
Normally I'd say try, href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80 /<dtml-var "REQUEST['REQUEST_URI']">;weblint" (the new Zope syntax is <dtml-XXX, but you can use <!--#var XXX--> if you want. But that doesn't work as REQUEST_URI gives a KeyError. This is weird because other REQUEST variables seem to work. Any deep voodoo Zopistas know why? <dtml-in "REQUEST.items()"> <dtml-var sequence-key> : <dtml-var sequence-item> <br> </dtml-in> Hint: To see all the REQUEST variables tack on /REQUEST to any URL you have (only works with Zope < 2.1.4) or put this in a dtml document <dtml-var REQUEST> To just get the environment variables; <dtml-in "REQUEST.environ.items()"> <dtml-var sequence-key> : <dtml-var sequence-item> <br> </dtml-in> So your code should work if you do this; href="http://validator.w3.org/check?uri=http://dnrdb.cbi.tamucc.edu:80 /<dtml-var "REQUEST.environ['REQUEST_URI']">;weblint" (If this seems long winded, it's because I'm writing this as I figure it out! :) Hint: Remember that anything inside "..." is a Python expression and Python, *not* Zope syntax applies.
I found this snippet of code for an echo and set, but my attempts at modifying it to work for this have failed.
<!--#call "REQUEST.set('varName', 'varValue')"--> <!--#var varName-->
That should work fine. hth Tone. ------ Dr Tony McDonald, FMCC, Networked Learning Environments Project http://nle.ncl.ac.uk/ The Medical School, Newcastle University Tel: +44 191 222 5888 Fingerprint: 3450 876D FA41 B926 D3DD F8C3 F2D0 C3B9 8B38 18A2
