How can I make a separate RSS feed for each custom post type?
I had searched the net for it and found suggestions to do something like this:
http://www.yoursite.com/feed/?post_type=book
I tried the above, but it just didn’t work! It only takes me back to the custom post type archive page again…
Does anybody knows where I went wrong or what I am missing???
FYI, I used the Custom Post Permalinks plugin to allow post type specific permalinks for post type archive pages. Not sure if this may affect the RSS feed problem.
Cheers!
add the small example function:
add_action( 'request', 'fb_add_to_feed' );
// add to post-feed
function fb_add_to_feed($request) {
if ( isset($request['feed']) && !isset($request['post_type']) ) {
$request['post_type'] = get_post_types( $args = array(
'public' => true,
'capability_type' => 'post'
) );
}
return $request;
}
Alternative you can creat a own feed onl yfor the custom post type. See the follow example for a “Draft Feed” of draft posts.
