try something like this, assuming the id of the folder you want is 'myFolder': <dtml-if expr="'myFolder' not in objectIds('Folder')"> <dtml-call expr="manage_addFolder('myFolder', 'title of my new folder')"> </dtml-if> The problem with using <dtml-in> is it will try to add the new folder once for every folder in the parent folder, and will fail to create the folder if the parent folder is empty. -Randy

Hi!

Perhaps something like this:

<dtml-in expr="objectValues('Folder')"> <dtml-if id==2001> Matches <dtml-else> <dtml-call "nameofFolder.manage_addFolder('titleofFolder', 'something else?')"> </dtml-if> </dtml-in>

You'll have to check if that actually works, because somehow it seems wrong... but anyhow, It should be enough to go on....

Im pretty much a newbie, but I had alot of help from the list today, so I try to return the favour : ) Cheers, Paz

I'm trying create a method to go through a site and create certain folders if they don't already exist. I can check for the existence of the folders with this:

<dtml-in expr="objectValues('Folder')"> <dtml-if "id=='2001'"> It matches<p> </dtml-if>

</dtml-in>

But how do I craft the "else" to create the folder? Obviously, if I throw the <dtml-else> inside the "in" loop, it'll throw itself into the "else" action for every iteration where it doesn't find the named folder.
