[Plugin: MultiTags] proper tags in RSS feeds

Hi upyup,

sorry to say, but adapting the feed is not possible from inside the plugin.
I have searched through the wordpress-code to find, where the feed-information is set. And that’s deep inside the core, without the possibility to hook into.

If you want to patch the core you can do so in wp-include/general-template.php

You find (in WP 3.0.1):

} elseif ( is_tag() ) {
		$tag_id = intval( get_query_var('tag_id') );
		$tag = get_tag( $tag_id );

		$title = esc_attr(sprintf( $args['tagtitle'], get_bloginfo('name'), $args['separator'], $tag->name ));
		$href = get_tag_feed_link( $tag_id );

You can replace $tag->name with multi_tags_get_title() (at least the title will then be better, but the link is still wrong)

I will add a convenience-function similar to “get_tag_feed_link” which will hanlde multiple tags, but you still have to change part of the core. Which is a bad thing.

For the 3.1 release the lines that have to be changed to get the “multi-tag”-feed working are a little bit different, than mentioned in the faq.

In wp-includes/general-template.php

you have to replace (in the if-branch ( is_tag() )):

$title = esc_attr(sprintf( $args['tagtitle'], get_bloginfo('name'), $args['separator'], $term->name ));
$href = get_tag_feed_link( $term->term_id );

with
if ( function_exists('multi_tags_get_title') )
$title = esc_attr(sprintf( $args['tagtitle'], get_bloginfo('name'), $args['separator'], multi_tags_get_title() ));
else
$title = esc_attr(sprintf( $args['tagtitle'], get_bloginfo('name'), $args['separator'], $term->name ));
if ( function_exists('multi_tags_get_tag_feed_link') )
$href = multi_tags_get_tag_feed_link( $tag_id );
else
$href = get_tag_feed_link( $term->term_id );


Hope you enjoy this plugin.
