function node_build_content
7.x node.module | node_build_content($node, |
6.x node.module | node_build_content($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.
