perhasp you can be more specific as to what _exactly_ you need? What
do you intend to do with he information. that has a bearing on how you
get it, and what form the result is in.
Try this:
<dtml-if URL2>
You can go up from here : <dtml-var URL0>
<dtml-else>
We're at the root folder: <dtml-var URL0>
</dtml-if>
This works because:
o URL0 is the root folder
o URL1 is the page you are looking: at it always exists.
o URL2 only exists if you are in a subfolder or sub-container
If you are needing this to build a navigation system, this may or may
not work fo ryou. You can look at the breadcrumbs howto, or wait a day
or so untill a new one is posted by yours truly, using python.
If all you need is the URL of the root folder, you can use <dtml-var
URL0>
Like i said, what you need it for, and how you need it determines how
to get it.
