# RSS-Feed Mediawiki extension
# using magpieRSS (http://magpierss.sourceforge.net/)
# by mutante 25.03.2005

# requiring magpie (see above)
require_once('magpierss-0.71.1/rss_fetch.inc');

# give it a name
$wgExtensionFunctions[] = "wfRssExtension";

# register with global parser (http://meta.wikimedia.org/wiki/Write_your_own_MediaWiki_extension)
function wfRssExtension() {
global $wgParser;

# set hook (trigger) to rss, means <rss> will be made active tag
$wgParser->setHook( "rss", "renderRss" );
}

# the actual function (taking input)
function renderRss( $input ) {

# maybe its a good idea to escape string user input so they dont try to attach nasty things
# $input = mysql_escape_string($input);

# fetch the feed (magpie's job)
$rss = fetch_rss($input);

# setting variables for table head
$link=$rss->channel['link'];
$title=$rss->channel['title'];
$cdesc=$rss->channel['description'];

# putting the html table head into the output variable

$output="<table><tr><th align='left' colspan='3'><i>RSS-feed included from:</th></tr>
<th colspan='2'><a href='$link'>$title</a></th>
<th><i>'$cdesc'</i></th></tr><tr><th>Date</th>
<th>Page</th><th>Description</th></tr>";

# now a loop to add table rows until none more are found

foreach ($rss->items as $item) {

# setting variables for table row

$href = $item['link'];
$title = $item['title'];
$date = $rss->dc['date'];
$description = $item['description'];

# adding each single row (still in loop) (.= appends = would overwrite)

$output.="<tr><td>date $date</td><td colspan='1'><a href='$href'>$title</a></td><td>$description</td></tr>";
}

# loop done ,adding final tag to close table properly
$output.="</table>";

# dump the output all at once
return $output;
