   I'm trying to figure out how to get custom fields into an RSS feed. I've created a new custom field key called "colour" and I want to have the value in my feed as well as the usual title and description, eg:

   <item>
   <title>Banana</title>
   <description>A long fruit that you peel.</description>
   <colour>Yellow</colour>
   </item>

   I've looked in Codex here:

   http://codex.wordpress.org/Custom_Fields

   But I can't figure it out. I've tried adding a line to the loop for colour to the RSS php file, but it doesn't work:

   <?php while (have_posts()) : the_post(); ?>
   <item>
   <title><?php the_title_rss() ?></title>
   <description><?php the_excerpt_rss() ?></description>
   <colour><?php get_post_meta($post->ID, $key, $single) ?></colour>
   <?php do_action('rss_item'); ?>
   </item>
   <?php endwhile; ?>

   Hopefully I'm missing something simple, any help much appreciated!

   The loop doesn't affect your RSS at all if you. if you know about filters you have to modify your RSS creating using

   <?php add_filter('rss_head', 'your_custom_fucntion_here') // rss 0.9 ?>
   <?php add_filter('rss2_head ', 'your_custom_fucntion_here') // rss2 ?>
   <?php add_filter('atom_head ', 'your_custom_fucntion_here') // atom ?>

   I cant't really give you the whole code at the moment but if you need all the code I may be able to write it later on if not read a bit about the hooks here
