   I am having a problem with the code given here for RSS feeds.

   <?php // Get RSS Feed(s)
   include_once(ABSPATH . WPINC . '/rss.php');
   $rss = fetch_rss('http://example.com/rss/feed/goes/here');
   $maxitems = 5;
   $items = array_slice($rss->items, 0, $maxitems);
   ?>
   
   <ul>
   <?php if (empty($items)) echo '<li>No items</li>';
   else
   foreach ( $items as $item ) : ?>
   <li><a href='<?php echo $item['link']; ?>'
   title='<?php echo $item['title']; ?>'>
   <?php echo $item['title']; ?>
   </a></li>
   <?php endforeach; ?>
   </ul>

   The site I am working on pulls an RSS feed from a calendar site; when the feed is empty, I want to display a message instead. This displays the RSS feed properly when it points to a feed w/content, but it does not display the message when the feed is empty.

   I would welcome *any* suggestions!

   It works for me, i've just plonked that into a theme on my test install, right in the header file and pointed it to an empty category feed at my website, i received the "No Items" message as expected...

   Am i missing something?

   What about using if(count($items) < 1) instead of if(empty($items))?

   Just a thought...

   Both should work...

   I can't replicate the problem though, it worked straight off.. :( ...

   I'd imagine counting is slower then checking if empty... (by milliseconds, lol) .. i'd stick with the if empty... :P

   (count($items) < 1) fixed it, thanks! :D

   How ironic, i'll eat my words... :)

   ** yum yum **

   Perhaps someone with access to the codex could update the page to use count instead..
