Hi all I've successfully implemented the Facebook RSS application, and limited the number of feed items to 8. However, I'd like to limit the amount of each item that shows, as per the Magpie tutorial here: http://www.howtoforge.com/rss_syndication_magpieRSS This is the code they suggest: Code: if (strlen($desc) >= 100) { $desc = substr($desc,0,99)."..."; } I don't see where this can go in the rss.php code from the HOWTO. Any thoughts?
Try this: Code: <?php define('MAGPIE_CACHE_DIR', './magpie_cache'); define('MAGPIE_CACHE_ON', 1); define('MAGPIE_CACHE_AGE', 600); require_once('appinclude.php'); require_once('rss/rss_fetch.inc'); $rss = @fetch_rss('http://www.howtoforge.com/node/feed'); $fbml = '<div style="margin:0 10px 0 10px;">'; $fbml .= '<table border="0" width="100%" style="margin: 5px 5px 5px 5px;"><tr><td valign="top" width="80%"><a href="'.$rss->channel['link'].'" style="font-weight: bold;">'.$rss->channel['title'].'</a></td><td valign="top" width="80%"><fb:share-button class="meta"> <meta name="medium" content="blog"/> <meta name="title" content="'.htmlspecialchars(strip_tags($rss->channel['title'])).'"/> <meta name="description" content="'.htmlspecialchars(strip_tags($rss->channel['description'])).'"/> <link rel="target_url" href="'.$rss->channel['link'].'"/> </fb:share-button></td></tr></table>'; foreach ($rss->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([B][COLOR="Red"]substr($item['description'],0,99)[/COLOR][/B])).'" /> <link rel="target_url" href="'.$item['link'].'" /> </fb:share-button></td></tr></table></div>'; if($item['description']) $fbml .= $item['description']; $fbml .= '</div>'; } $fbml .= '</div>'; $facebook->api_client->profile_setFBML($fbml, $user); echo $fbml; ?>
Thanks falko, that works, although the extra code has to be put here as well: Code: <?php define('MAGPIE_CACHE_DIR', './magpie_cache'); define('MAGPIE_CACHE_ON', 1); define('MAGPIE_CACHE_AGE', 600); require_once('appinclude.php'); require_once('rss/rss_fetch.inc'); $rss = @fetch_rss('http://www.howtoforge.com/node/feed'); $fbml = '<div style="margin:0 10px 0 10px;">'; $fbml .= '<table border="0" width="100%" style="margin: 5px 5px 5px 5px;"><tr><td valign="top" width="80%"><a href="'.$rss->channel['link'].'" style="font-weight: bold;">'.$rss->channel['title'].'</a></td><td valign="top" width="80%"><fb:share-button class="meta"> <meta name="medium" content="blog"/> <meta name="title" content="'.htmlspecialchars(strip_tags($rss->channel['title'])).'"/> <meta name="description" content="'.htmlspecialchars(strip_tags($rss->channel['description'])).'"/> <link rel="target_url" href="'.$rss->channel['link'].'"/> </fb:share-button></td></tr></table>'; foreach ($rss->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(substr($item['description'],0,99))).'" /> <link rel="target_url" href="'.$item['link'].'" /> </fb:share-button></td></tr></table></div>'; if($item['description']) $fbml .= [COLOR="Red"]substr($item['description'],0,99)[/COLOR]; $fbml .= '</div>'; } $fbml .= '</div>'; $facebook->api_client->profile_setFBML($fbml, $user); echo $fbml; ?> Thanks again
I've got a problem with the script. When there are no items in my RSS feed I see the following error on my facebook application page/profile: Code: Warning: array_slice() [function.array-slice]: The first argument should be an array in /data/www/domain.co.uk/www/fb/rss.php on line 20 Warning: Invalid argument supplied for foreach() in /data/www/domain.co.uk/www/fb/rss.php on line 22 Presumably it's because the array is empty. My php skills don't stretch to working out what to do though
Try this: Code: [B][COLOR="Red"]if(is_array($rss->items) && !empty($rss->items)){[/COLOR][/B] foreach ($rss->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(substr($item['description'],0,99))).'" /> <link rel="target_url" href="'.$item['link'].'" /> </fb:share-button></td></tr></table></div>'; if($item['description']) $fbml .= substr($item['description'],0,99); $fbml .= '</div>'; } [B][COLOR="Red"]}[/COLOR][/B]
