Versions
7 – 8 hook_node_view($node, $view_mode, $langcode)

Act on a node that is being assembled before rendering.

The module may add elements to $node->content prior to rendering. This hook will be called after hook_view(). The structure of $node->content is a renderable array as expected by drupal_render().

When $view_mode is 'rss', modules can also add extra RSS elements and namespaces to $node->rss_elements and $node->rss_namespaces respectively for the RSS item generated for this node. For details on how this is used, see node_feed().

Parameters

$node The node that is being assembled for rendering.

$view_mode The $view_mode parameter from node_view().

$langcode The language code used for rendering.
