Problem with your FaceBook Tutorial
 
Firstly, great tutorial!
I'm trying to make it display only the 5 most recent entries in my facebook application. I've tried doing what the Magpie RSS howto says, but it says:
Quote:

Warning: Invalid argument supplied for foreach() in /usr/home/omgponi/public_html/fb/simplyhappynews/rss.php on line 21
my application code is as follows (Line 9 is the custom code, and I've renamed subsequent variables to use the new array, no dice.):
PHP Code:

<?php
include('conf.php');
define('MAGPIE_CACHE_DIR'$magpie_cache_dir);
define('MAGPIE_CACHE_ON'0);
define('MAGPIE_CACHE_AGE'600);

require_once(
'rss/rss_fetch.inc');
$rss = @fetch_rss($feed);
$rssitems array_slice($rss->items05);

$fbml '<fb:header decoration="no_padding">Simply Happy News</fb:header><div style="margin:0 10px 0 10px;">';
$fbml .= '<table border="0" width="100%" style="margin: 5px 5px 5px 5px;"><tr><td valign="top" width="80%"><a href="'.$rssitems->channel['link'].'" style="font-weight: bold;">'.$rssitems->channel['title'].'</a></td><td valign="top" width="80%"><fb:share-button class="meta">
  <meta name="medium" content="blog"/>
  <meta name="title" content="'
.htmlspecialchars(strip_tags($rssitems->channel['title'])).'"/>
  <meta name="description" content="'
.htmlspecialchars(strip_tags($rssitems->channel['description'])).'"/>
  <link rel="target_url" href="'
.$rssitems->channel['link'].'"/>
</fb:share-button></td></tr></table>'
;



foreach (
$rssitems->items as $item) {
        
$fbml .= '<div style="border-bottom: 2px solid #CCCCCC; padding-bottom:5px;"><br><div style="border-bottom: 1px dotted #CCCCCC; border-top: 1px dotted #CCCCCC;"><table border="0" width="100%" style="margin: 5px 5px 5px 5px;"><tr><td valign="top" width="80%"><a href="'.$item['link'].'" style="font-weight: bold;">'.$item['title'].'</a></td><td valign="top" width="80%"><fb:share-button class="meta">
  <meta name="medium" content="blog" />
  <meta name="title" content="'
.htmlspecialchars(strip_tags($item['title'])).'" />
  <meta name="description" content="'
.htmlspecialchars(strip_tags($item['description'])).'" />
  <link rel="target_url" href="'
.$item['link'].'" />
</fb:share-button></td></tr></table></div>'
;
        if(
$item['description']) $fbml .= $item['description'];
        
$fbml .= '</div>';
}
$fbml .= '</div>';

echo 
$fbml;

?>


Any ideas? Its really frustrating :)

I'd fill in the following line right after
Code:

$rss = @fetch_rss($feed);
for debugging purposes:
Code:

print_r($rss);
That way you see what's in $rss->items.

BTW, where did you define $feed?
