I'm using Drupal 7, and trying to work some magic from within a hook_node_presave() function.
I have a node reference field, and I'm trying to get the name of the referenced node rather than nid. When I trace out the field (
$node->field_my_name) I get the following
Array ( [und] => Array (  => Array ( [nid] => 23 ) ) )
I wondering if there is a way to get the title without doing a full load of the referenced node. Is there anyway I can do this with a token? Would this no be an issue if I were using entity reference rather than references?
