I have a content who contains an unlimited collection field. Via a custom module, how can I get and set the informations which are in field collection in the content (nid) ?
I have read the api documentation of field collection but I don't understand how it works (I'm french..) By example I see this function : field_collection_item_load, the parameter is an item but...what is an item ? xD
Another question, my field collection contains an another field collection. Is there a particular way to get and set this "sub"-field collection ?
If you can me a very sample example of get and set, I thank you very much
