function _trigger_normalize_node_context

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 the node hook, the user object is not available since the node hook doesn't pass it. So here we load the object the action expects.

Parameters

$type: The type of action that is about to be called.

$node: The node that was passed via the nodeapi hook.

Return value

The object expected by the action that is about to be called.

File

modules/trigger/trigger.module, line 196

Enables functions to be stored and executed at a later time when triggered by other modules or by one of Drupal's core API hooks.

Code

function _trigger_normalize_node_context($type, $node) {
  switch ($type) {

    // If an action that works on comments is being called in a node context,
    // the action is expecting a comment object. But we do not know which comment
    // to give it. The first? The most recent? All of them? So comment actions
    // in a node context are not supported.
    // 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(array(
        'uid' => $node->uid,
      ));
  }
}
