[support] Accessing values in the $node variable..

[Lucas D Hedding]

If don't mind trying something new, I'd recommend using
entity_metadata_wrapper from the entity API.

Here's a specific
example<http://www.appnovation.com/part_2_entity_metadata_wrappers_and_entity_api>using
field collections and a more general
example <https://drupal.org/node/1021556>. I've found
entity_metadata_wrapper to be much easier than dealing with $node->field_foo
[LANGUAGE_NONE][0]['value'] all over the place. Place a dependency on
entity in your .info file and have fun.
