Loads associated objects for node triggers.
When an action is called in a context that does not match its type, the object that the action expects must be retrieved. For example, when an action that works on users is called during a node hook implementation, the user object is not available since the node hook call doesn't pass it. So here we load the object the action expects.
$type: The type of action that is about to be called.
$node: The node that was passed via the node hook.
The object expected by the action that is about to be called.
function _trigger_normalize_node_context($type, $node) {
// Note that comment-type actions are not supported in node contexts,
// because we wouldn't know which comment to choose.
switch ($type) {
// An action that works on users is being called in a node context.
// Load the user object of the node's author.
case 'user':
return user_load($node->uid);
}
