I have been struggling with the following problem:
The default wordpress RSS Feed includes also tags in category function. As a result, if you use a merge tag to show the post category (i.e. I am using RSS campaign on Mailchimp to send emails to my subscribers) it shows the category and in addition all the tags.
I looked around and located the file '/wp-includes/feed.php' on line #301 there's the relevant code. I am including it here as well:
function get_the_category_rss($type = null) {
if ( empty($type) )
$type = get_default_feed();
$categories = get_the_category();
$tags = get_the_tags();
$the_list = '';
$cat_names = array();
$filter = 'rss';
if ( 'atom' == $type )
$filter = 'raw';
if ( !empty($categories) ) foreach ( (array) $categories as $category ) {
$cat_names[] = sanitize_term_field('name', $category->name, $category->term_id, 'category', $filter);
}
if ( !empty($tags) ) foreach ( (array) $tags as $tag ) {
$cat_names[] = sanitize_term_field('name', $tag->name, $tag->term_id, 'post_tag', $filter);
}
$cat_names = array_unique($cat_names);
foreach ( $cat_names as $cat_name ) {
if ( 'rdf' == $type )
$the_list .= "\t\t<dc:subject><![CDATA[$cat_name]]></dc:subject>\n";
elseif ( 'atom' == $type )
$the_list .= sprintf( '<category scheme="%1$s" term="%2$s" />', esc_attr( apply_filters( 'get_bloginfo_rss', get_bloginfo( 'url' ) ) ), esc_attr( $cat_name ) );
else
$the_list .= "\t\t<category><![CDATA[" . @html_entity_decode( $cat_name, ENT_COMPAT, get_option('blog_charset') ) . "]]></category>\n";
}
return apply_filters('the_category_rss', $the_list, $type);
}
I understand that I can fix the problem by deleting the following lines:
$tags = get_the_tags();
and
if ( !empty($tags) ) foreach ( (array) $tags as $tag ) {
$cat_names[] = sanitize_term_field('name', $tag->name, $tag->term_id, 'post_tag', $filter);
}
I don't want to edit core files though. I also tried to find a plugin, but no luck.
Is there a filter I could use to resolve this in order to avoid editing core files?
Thank you in advance for any help! Kat

Reset to default 1Try this - think I found this from little mike.
add_filter('get_the_tags', 'strip_tags_from_feeds');
function strip_tags_from_feeds($terms) {
if (is_feed())
return array();
return $terms;
}
