How to Display The Feed Content of a Website in WordPress

The fetch_feed is a built-in WordPress function that retrieves and parses an external feed.
Under-the-hood, it’s powered by SimplePie – a very fast and easy-to-use PHP feed parser.

Follow me as I walk us through the steps in using fetch_feed to display the feed content of this blog (w3guy.com).

First, include the feed.php file at wp-includes folder.


<?php
include_once( ABSPATH . WPINC . '/feed.php' );

Use the fetch_feed function to get a SimplePie feed object from the feed source.
```
$rss = fetch_feed( 'https://w3guy.com/feed' );
```
Halt execution if fetch_feed result to an error.
```
if ( is_wp_error( $rss ) )
return;
```
Determine the total feed items, but limit it to a maximum of eight (8).
```
$maxitems = $rss->get_item_quantity( 5 );
```
Build an array of all the items, starting with first element (element 0).
```
$rss_items = $rss->get_items( 0, $maxitems ); 
```

If there is no feed item, output the text No feed item otherwise Loop through each feed item and display each item as a hyperlink.


<ul>
	<?php if ( $maxitems == 0 ) : ?>
		<li><?php echo 'No feed item'; ?></li>
	<?php else : ?>
		<?php foreach ( $rss_items as $item ) : ?>
			<li>
				<a href="<?php echo esc_url( $item->get_permalink() ); ?>"
				   title="<?php printf( 'Posted %s', $item->get_date( 'j F Y | g:i a' ) ); ?>">
					<?php echo esc_html( $item->get_title() ); ?>
				</a>
			</li>
		<?php endforeach; ?>
	<?php endif; ?>
</ul>

Execute the code and you should see the feed content displayed as shown in the image below.

Here’s the entire plugin code:


<h2>Blog Update from W3Guy</h2>

<?php
include_once( ABSPATH . WPINC . '/feed.php' );

// Get a SimplePie feed object from the specified feed source.
$rss = fetch_feed( 'https://w3guy.com/feed' );

if ( is_wp_error( $rss ) ) {
	return;
}

// 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 );
?>

<ul>
	<?php if ( $maxitems == 0 ) : ?>
		<li><?php echo 'No feed item'; ?></li>
	<?php else : ?>
		<?php foreach ( $rss_items as $item ) : ?>
			<li>
				<a href="<?php echo esc_url( $item->get_permalink() ); ?>"
				   title="<?php printf( 'Posted %s', $item->get_date( 'j F Y | g:i a' ) ); ?>">
					<?php echo esc_html( $item->get_title() ); ?>
				</a>
			</li>
		<?php endforeach; ?>
	<?php endif; ?>
</ul>

Want to use the script, simply bundle it with a theme or plugin.
