I made a DTML method which works, but doesn't do it
recursively. I'll try external methods.
Thanks..
<dtml-if fname>
<dtml-try "_.getitem(_['fname'],1)">
<dtml-with "_.getitem(_['fname'],1)">
<dtml-var title>
<dtml-unless "meta_type=='Folder'">
Item exists, but not a folder
</dtml-unless>
</dtml-with>
<dtml-except>
Folder not found
<dtml-if ftitle>
<dtml-try>
<dtml-call "manage_addFolder(_['fname'],_['ftitle'])">
Folder Created
<dtml-except>
Folder could not be created
</dtml-try>
<dtml-else>
<dtml-try>
<dtml-call "manage_addFolder(_['fname'],_['fname'])">
Folder Created
<dtml-except>
Folder could not be created
</dtml-try>
</dtml-if>
</dtml-try>
</dtml-if fname>
