Want to redirect your WordPress default RSS feed to for example Feedburner? Add this in your theme’s functions.php and change to your custom feed link.
/* Custom rss feed
/* ------------------------------------ */
function alx_custom_rss_feed( $output, $feed ) {
// Do not redirect comments feed
if ( strpos( $output, 'comments' ) )
return $output;
return esc_url('http://feeds.feedburner.com/MyFeed/');
}
add_filter( 'feed_link', 'alx_custom_rss_feed' , 10, 2 );
The comments feed will remain the same.
