How to Identify Fields from Field Collection? I have a Content Type, which has field collection and I need to load the fields present inside the field collection, Any idea on how to do this?

Very Important Note: There is no content created for this Content Type as yet.
This'll do it:

$entity_type = 'field_collection_item';
$bundle_name = 'field_profile_address';

$info = field_info_instances($entity_type, $bundle_name);

// $info at this point is an array of fields attached to the queried bundle.


From your last 2 questions I think you'd be very interested in the Field Info API docs.
