function node_build_content

7.x node.module node_build_content($node, $view_mode = 'full', $langcode = NULL)
6.x node.module node_build_content($node, $teaser = FALSE, $page = FALSE)

Builds a structured array representing the node's content.

The content built for the node (field values, comments, file attachments or other node components) will vary depending on the $view_mode parameter.

Drupal core defines the following view modes for nodes, with the following default use cases:

  • full (default): node is being displayed on its own page (node/123)
  • teaser: node is being displayed on the default home page listing, on taxonomy listing pages, or on blog listing pages.
  • rss: node displayed in an RSS feed.

If search.module is enabled:

  • search_index: node is being indexed for search.
  • search_result: node is being displayed as a search result.

If book.module is enabled:

  • print: node is being displayed in print-friendly mode.

Contributed modules might define additional view modes, or use existing view modes in additional contexts.

Parameters

$node: A node object.

$view_mode: View mode, e.g. 'full', 'teaser'...

$langcode: (optional) A language code to use for rendering. Defaults to the global content language of the current request.
