   I'm a relative noob trying to filter post content selectively.

   In my installation, only posts in one category include the custom fields "sponsor text" and "sponsor link".

   If I create a custom category loop by category, the custom fields do not show up in single posts; if I apply it globally, then the special div to hold the meta data appears on ALL posts, even where the custom field data doesn't exist.

   Here is the global function:

   //  Custom Category Loop 
   
   function remove_category_loop(){ //  first remove the thematic action
       remove_action('thematic_categoryloop', 'thematic_category_loop');
       remove_action('thematic_archiveloop', 'thematic_archive_loop');
   }
   add_action('init','remove_category_loop');
   
   function child_category_loop() { // now rebuild your version of the action
   
    while (have_posts()) : the_post();
   
   	 global $post;
        $sponsortext = get_post_meta($post->ID , 'sponsor', true);
   	 $sponsorlink = get_post_meta($post->ID , 'sponsorlink', true);
   	 ?>
   
           <div id="post-<?php the_ID(); ?>" class="<?php thematic_post_class(); ?>">
              <?php thematic_postheader(); ?>
              <div class="entry-content">
                <?php thematic_content(); ?>
                <div id="sponsor">
   	<p><?php echo $sponsortext; ?></p>
       <p>For more information visit the website, <a href="http://<?php echo $sponsorlink; ?>" target="_blank">http://<?php echo $sponsorlink; ?></a></p>
       </div>
              </div>
              <?php thematic_postfooter(); ?>
           </div><!-- .post -->
   
        <?php endwhile;
   }
   
   add_action('thematic_categoryloop', 'child_category_loop');
   add_action('thematic_archiveloop', 'child_category_loop');

   This code works great for the one category page, http://seacliffmm.com/prod/centurion/category/clients-testimonials/,
   But not for the general blog category page, http://seacliffmm.com/prod/centurion/category/news/

   I'm sure the answer is an if-else construction,but so far I haven't been able to code one that works.

   Please advise, if possible.

   "if I apply it globally"

   does that mean you tried filtering the_content()?

   which is what i'd do and just add in a condition to test if $sponsortext exists

   function add_after_content($content) {
   
     global $post;
     $sponsortext = get_post_meta($post->ID , 'sponsor', true);
     $sponsorlink = get_post_meta($post->ID , 'sponsorlink', true);
   
     if($sponsortext && $sponsorlink){
       $sponsor = '<div id="sponsor">';
       $sponsor .= '<p>'. $sponsortext.'</p>';
       $sponsor .= '<p>For more information visit the website, <a href="http://'.$sponsorlink.'>" target="_blank">http://'.$sponsorlink.'</a></p>';
       $sponsor .= '</div>';
   
       $content .= $sponsor ;
     }
     return $content;
   }
   add_filter('the_content', add_after_content);

   totally untested, you might need to escape the backslashes... i'm not sure, but i think the concept is right.

   ps- you can now use

   function childtheme_override_category_loop()

   and you don't need to add or remove any actions. it's magic.

   For the most part, that worked like a charm: http://seacliffmm.com/prod/centurion/clients-testimonials/build-a-bear-workshop/. One remaining issue is that the &sponsorlink call is generating an extra character string, %3e, that is messing up the actual sponsor's links. Any idea where that's coming from?

   Other than that, it's beautiful. I knew some kind of conditional test was the answer; I just kept messing up the syntax for so many hours that I got frustrated. Thanks for demonstrating it so clearly.

   Yes, I've seen the function childtheme_override_category_loop() in the newer version of thematic, but have not (until now) had occasion to use it.

   Will file your magic and tips for future use.
