Take a look at how the 'folder_contents' form is built:
it consists of checkboxes, one per content item, where
each box is named 'ids:list'.  Zope marshalls *all* form
fields with the ':list' suffix into a single list, named
with the prefix (in this case, 'ids').  So, you would write
your function something like what 'folder_copy' does, e.g.::

  ## Script (Python) "folder_publish"
  ##title=Publish selected content
  ##parameters=
  REQUEST=context.REQUEST
  if REQUEST.has_key('ids'):
    for id in ids:
      obj = getattr( context, id )
      context.portal_workflow.doActionFor(obj,
                'publish',comment='published by Bender')
    return REQUEST.RESPONSE.redirect(context.absolute_url()
     + '/folder_contents?portal_status_message=Item(s)+Published.')
  else:
    return REQUEST.RESPONSE.redirect(context.absolute_url()
     + '/folder_contents?portal_status_message='
     + 'Please+select+one+or+more+items+to+publish+first.')

Note that the action of the form in 'folder_contents' is the
'absolute_url' of the folder.  How then does this list get passed
to your function?  Notice the names of the various submit buttons
at the bottom of the form:  each one has the ':method' suffix,
which signals Zope to dispatch the request to the corresponding
method of the same name.  So, if you name your method
'folder_publish', you would add a button to your form::

   <input type="submit" name="folder_publish:method"
          value="Publish">

Hope that helps,

Tres.
