Retrieves an external feed and parses it. Uses the SimplePie and FeedCache functionality for retrieval and parsing and automatic caching.
<?php $feed = fetch_feed( $uri ); ?>
This example will retrieve and display a list of links for an existing RSS feed, limiting the selection to the five most recent items:
<h2><?php _e( 'Recent news from Some-Other Blog:', 'my-text-domain' ); ?></h2>
<?php // Get RSS Feed(s)
include_once( ABSPATH . WPINC . '/feed.php' );
// Get a SimplePie feed object from the specified feed source.
$rss = fetch_feed( 'http://example.com/rss/feed/goes/here' );
$maxitems = 0;
if ( ! is_wp_error( $rss ) ) : // Checks that the object is created correctly
// Figure out how many total items there are, but limit it to 5.
$maxitems = $rss->get_item_quantity( 5 );
// Build an array of all the items, starting with element 0 (first element).
$rss_items = $rss->get_items( 0, $maxitems );
endif;
?>
<ul>
<?php if ( $maxitems == 0 ) : ?>
<li><?php _e( 'No items', 'my-text-domain' ); ?></li>
<?php else : ?>
<?php // Loop through each feed item and display each item as a hyperlink. ?>
<?php foreach ( $rss_items as $item ) : ?>
<li>
<a href="<?php echo esc_url( $item->get_permalink() ); ?>"
title="<?php printf( __( 'Posted %s', 'my-text-domain' ), $item->get_date('j F Y | g:i a') ); ?>">
<?php echo esc_html( $item->get_title() ); ?>
</a>
</li>
<?php endforeach; ?>
<?php endif; ?>
</ul>
fetch_feed caches results for 12 hours by default. You can modify this by modifying the time interval via the filter wp_feed_cache_transient_lifetime.
Since Version 2.8
fetch_feed is defined in wp-includes/feed.php.
