de.bitfolge.feedcreator

1. Documentation:

de.bitfolge.feedcreator is a MidCOM library for adding RSS and Atom feeds into component output. It uses the LGPLd FeedCreator class library by Kai Blankenhorn.

Documentation:

Usage is relatively simple. First you need to include the library into the _autoload_libraries array of your component's interface class:

$this->_autoload_libraries = Array(
    'midcom.helper.datamanager',
    'de.bitfolge.feedcreator',
);

Then in your viewer class create a handler method for RSS output that skips regular style output:

$_MIDCOM->skip_page_style = true;

And finally in the RSS output's show method populate and show the feed (example from net.nemein.wiki):

$nap = new midcom_helper_nav();
$node = $nap->get_node($nap->get_current_node());

$_MIDCOM->cache->content->content_type("text/xml");
$_MIDCOM->header("Content-type: text/xml; charset=UTF-8");

$rss = new UniversalFeedCreator();
$rss->title = $node[MIDCOM_NAV_NAME];
$rss->link = $node[MIDCOM_NAV_FULLURL];
$rss->syndicationURL = "{$node[MIDCOM_NAV_FULLURL]}rss.xml";
$rss->cssStyleSheet = false;

$count = 20;
$wikipages = mgd_list_topic_articles($this->_topic->id, 'reverse revised');
if ($wikipages)
{
    while (   $wikipages->fetch() 
           && $count)
    {
        $wikipage = mgd_get_article($wikipages->id);
        $author = mgd_get_person($wikipage->revisor);
        $item = new FeedItem();
        $item->title = $wikipage->title;
        $item->link = "{$node[MIDCOM_NAV_FULLURL]}{$wikipage->name}/";
        $item->date = $wikipage->revised;
        $item->author = $author->name;
        $item->description = $wikipage->content;
        $rss->addItem($item);
        $count--;
    }
}      
echo $rss->createFeed('RSS2.0');
debug_pop();
// This will exit
$_MIDCOM->finish();
