Remove or Edit <dc:creator>in Feeds

Question

Would like to remove or edit it to be a static value without editing core Wordpress files. Preferably as a function.

Answer 1

1. Copy /wp-includes/feed-rss2.php to your theme folder

2. Edit it and make whatever changes you desire (e.g. removing the line for dc:creator)

3. in your theme's functions.php file, add the following function:

remove_all_actions( 'do_feed_rss2' );  
function create_my_custom_feed() {  
    load_template( TEMPLATEPATH . '/feed-rss2.php');  
}  
add_action('do_feed_rss2', 'create_my_custom_feed', 10, 1);

Edit by Otto: While that will work, this would be a better way:

function create_my_custom_feed() {  
    load_template( TEMPLATEPATH . '/feed-rss2.php');  
}  
add_feed('rss2', 'create_my_custom_feed');

The add_feed function is smart, and will handle the actions and such for you.

Answer 2

Unfortunately, that element is hard-coded into WordPress core. Take a look at /wp-includes/feed-rss2.php:

<item>
    <title><?php the_title_rss() ?></title>
    <link><?php the_permalink_rss() ?></link>
    <comments><?php comments_link_feed(); ?></comments>
    <pubDate><?php echo mysql2date('D, d M Y H:i:s +0000', get_post_time('Y-m-d H:i:s', true), false); ?></pubDate>
    <dc:creator><?php the_author() ?></dc:creator>
    <?php the_category_rss('rss2') ?>

    <guid isPermaLink="false"><?php the_guid(); ?></guid>
<?php if (get_option('rss_use_excerpt')) : ?>
    <description><![CDATA[<?php the_excerpt_rss() ?>]]></description>
<?php else : ?>
    <description><![CDATA[<?php the_excerpt_rss() ?>]]></description>
    <?php if ( strlen( $post->post_content ) > 0 ) : ?>
        <content:encoded><![CDATA[<?php the_content_feed('rss2') ?>]]></content:encoded>
    <?php else : ?>
        <content:encoded><![CDATA[<?php the_excerpt_rss() ?>]]></content:encoded>
    <?php endif; ?>
<?php endif; ?>
    <wfw:commentRss><?php echo esc_url( get_post_comments_feed_link(null, 'rss2') ); ?></wfw:commentRss>
    <slash:comments><?php echo get_comments_number(); ?></slash:comments>
<?php rss_enclosure(); ?>
<?php do_action('rss2_item'); ?>
</item>
