One of my clients needs to pull an RSS feed from a real estate virtual tour provider and display it on one of their pages. I looked into a few plugins and could not find one that was easily customizable. After a quick google search I discovered that WordPress has some built-in functions based off of SimplePie‘s easy to use RSS API.
I also needed to customize the output a little bit, which required me to rely on PHP’s preg_match and preg_replace functions. Here is some simple example for embedding a feed into your WordPess website:
include_once(ABSPATH.WPINC.'/rss.php'); // path to include script
$feed = fetch_feed('http://url.to.feed/'); // specify feed url
if (!is_wp_error($feed)) :
$rss_items = $feed->get_items();
// Loop through each feed item and display each item as a hyperlink.
<?php foreach ( $rss_items as $item ) : ?>
<?php echo $item->get_title(); ?>
<?php endforeach; ?>
