Generates and prints an RSS feed.

Generates an RSS feed from an array of node IDs, and prints it with an HTTP header, with Content Type set to RSS/XML.


$nids: An array of node IDs (nid). Defaults to FALSE so empty feeds can be generated with passing an empty array, if no items are to be added to the feed.

$channel: An associative array containing title, link, description and other keys, to be parsed by format_rss_channel() and format_xml_elements(). A list of channel elements can be found at the RSS 2.0 Specification. The link should be an absolute URL.

4 calls to node_feed()
blog_feed_last in modules/blog/blog.pages.inc
Menu callback; displays an RSS feed containing recent blog entries of all users.
blog_feed_user in modules/blog/blog.pages.inc
Menu callback; displays an RSS feed containing recent blog entries of a given user.
NodeFeedTestCase::testNodeFeedExtraChannelElements in modules/node/node.test
Ensures that node_feed() accepts and prints extra channel elements.
taxonomy_term_feed in modules/taxonomy/taxonomy.pages.inc
Generate the content feed for a taxonomy term.
1 string reference to 'node_feed'
node_menu in modules/node/node.module
Implements hook_menu().

I'm getting "malformed entity" errors when I use this function. I can load the nodes in question with entity_load or node_load_multiple without error, but when I attempt to feed the same array of nids to node_feed, I get:

EntityMalformedException: Missing bundle property on entity of type node. in entity_extract_ids() (line 7633 of /var/www/vhosts/test.cms.mo.gov/httpdocs/includes/common.inc).

Anyone else seen, or better yet, solved this?
