Have you ever wanted to add an external RSS feed to your WordPress blog? This is a great way to promote one of your other blogs (if it is in a similar niche) on a more popular site you run.
Most of you will probably remember that about a month ago we finally got around to launching our WordPress Forums, which has an RSS feed associated with it. In order to cross-promote our forums on this site, I wanted to display our most recent forum posts in the sidebar here at WordPress Hacks.
In order to accomplish this, I grabbed the following code from Jean’s post over at Smashing Magazine:
wp_rss('http://wpforums.com/external.php?type=RSS2', 5); ?>
It takes the rss.php file that is built into WordPress (used for widgets). In this code it is set to display the most recent 5 posts from the RSS feed “http://wpforums.com/external.php?type=RSS2.”
Here is how it looks:
I have gone ahead and added this to our WordPress Code page for easy reference.
