    Hi

    I’ve been playing around with this for over an hour and I’ve searched for clues but no luck. I think I’m just lacking some basic PHP knowledge to solve this.

    I have the following code working fine for me:

    <?php
	include_once(ABSPATH.WPINC.'/rss.php'); // path to include script
	$feed = fetch_rss('FEED-URL'); // specify feed url
	$items = array_slice($feed->items, 0, 3); // specify first item and duration
?>
<?php if (!empty($items)) : ?>
<?php foreach ($items as $item) : ?>
<a href="<?php echo $item['link']; ?>"><?php echo $item['description']; ?></a>
<?php endforeach; ?>
<?php endif; ?>

    This gives me three latest posts. How do I keep the selection to 3 items but have it be random posts?

    Thanks

  • Use shuffle().

    Try below code.

    <?php
include_once(ABSPATH.WPINC.'/rss.php'); // path to include script
$feed = fetch_rss('FEED-URL'); // specify feed url
shuffle($feed->items);
$items = array_slice($feed->items, 0, 3); // specify first item and duration

if(!empty($items)){
	foreach ($items as $item){
		echo '<a href="'.$item['link'].'">'.$item['description'].'</a>';
	}
}
?>

    Hello
    Im having an issue with calling a custom field variable into the feed url.

    I basically want a page to show a different feed url based on whats been inputed into the custom field option. How would i implement this using this setup.

    <?php
	   $feeds =  get_post_meta($post->ID, 'feeds',true);
?>
<?php
	include_once(ABSPATH.WPINC.'/rss.php'); // path to include script
	$feed = fetch_rss('FEED-URL I WANT TO CALL FROM A CUSTOM FIELD'); // specify feed url
	$items = array_slice($feed->items, 0, 3); // specify first item and duration
?>
<?php if (!empty($items)) : ?>
<?php foreach ($items as $item) : ?>
<a href="<?php echo $item['link']; ?>"><?php echo $item['description']; ?></a>
<?php endforeach; ?>
<?php endif; ?>

    thanks in advanced to anyone with a solution.
