[Mediawiki-l] Extension help

[Jim Hu]

I don't understand why you have those lines in LocalSettings.  You  
should only have to put

> 192 include_once("extensions/magpierss/rss.php");

in LocalSettings, after saving the extension code as a file in the  
extensions directory.  Assuming that you are using the extension code at

http://meta.wikimedia.org/wiki/User:Alxndr/RSS

that code calls the magpierss library.

By putting

> 191 $rss = fetch_rss($url);


in LocalSettings, you're sending an undefined value, $url, to magpie.   
The extension is supposed to get the url from the wikitext of the page  
where you are including the feed, e.g. <rss>http://myfeed.com</rss>
