Wordpress Category external feed plugin

This wordpress plugin is for show custom external rss feed in category page.

For example if you want a category page list rss feed from another site category page, this is for you.

It is my first wordpress plugin (ok, maybe not exactly the very first hello world like ;)

It use simplepie because I like it. (it is included in package and license is almost compatible)

User guide

• Install and set cache folder writeable by server
• Edit category and set feed url
• Use simplepie api to access data returned by get_catfeed_feed($cat) (see simplepie)

example (in archive.php theme file):
{syntaxhighlighter brush:php}
if (is_category()) :
if($feed = get_catfeed_feed($cat)) :
?>

get_title() ?>

foreach($feed->get_items(0,10) as $item) :
?>

endforeach;
endif;
endif;
?>
{/syntaxhighlighter}

Tech info
Plugin create a new db table ($table_prefix.'category_ext_feed') with feedtitle and feedurl fields.

Note: it works only on edit category, not creation, because I do not know how to get category id on creation .. and documentation is missing
