[TYPO3-english] retrieve IDs of content items in FCE?

[Erich Specht]

Thank you for the reply, Torsten.  The problem with that solution is that
each time a user copies a page with the FCE on it, I believe the copy will
have a new ID so the typoscript won't be looking at the new copy of the FCE.

Is there another way to access the IDs of content items within an FCE on a
page - perhaps by field name rather than ID of the FCE?

Yes, you can do that using the XPATH cObj. Check out the tutorial on how to
get values from a tt_content flexform:

http://typo3.org/extensions/repository/view/cobj_xpath
http://typo3.org/extension-manuals/cobj_xpath/1.1.1/view/1/4/#id547457

Its basically the same for FCEs since they also store their values in XML.
You may adapt the following snippet to your structure:

lib.xpath = XPATH
lib.xpath {
  source.data = DB : tt_content:###YOUR_FCE_ID###:tx_templavoila_flex
  return = string
  expression = //field[@index="###YOUR_FIELDNAME###"]/value
  resultObj {
    cObjNum = 1
    1.current = 1
  }
}

Have fun,
Torsten
