WordPress tutorials: Fetch and display RSS

Wpsnipp – Do you know that WordPress have a built-in RSS reader? Some time ago, I published a recipe to let you know how to use it. Today, I’m glad to show you an updated version of this very popular hack.This script will fetch an RSS feed and display it within your wordpress theme. Make sure you change the feed URL highlighted on line 4.



<?php if(function_exists('fetch_feed')) {
$feed = fetch_feed('http://feeds.feedburner.com/catswhoblog');
$limit = $feed->get_item_quantity(7); // specify number of items
$items = $feed->get_items(0, $limit); // create an array of items
if ($limit == 0) echo '<div>The feed is either empty or unavailable.</div>';
else foreach ($items as $item) : ?>
<a href="<?php echo $item->get_permalink(); ?>"
title="<?php echo $item->get_date('j F Y @ g:i a'); ?>">
<?php echo $item->get_title(); ?>
<?php echo substr($item->get_description(), 0, 200); ?>
<?php endforeach; ?>
