Hello,
I ask about how to detect root in the list and Got three answer:
<dtml-if "_.len(PARENTS) == 1"> We're at the root folder <dtml-else> You can go up from here </dtml-if>
<dtml-if "title == 'Zope'">
Title is Zope <dtml-else> No title not zope </dtml-if>
<dtml-if "id == ''"> root folder have not identity <dtml-else> there is id </dtml-if>
However, all of them fail working in virtual web with siteroot set. How can I detect the root with or without siteroot?
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. HTH, Bill
