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. helgatheviking on "Add post_meta custom field data only when fields are true" http://themeshaper.com/forums/topic/add-post_meta-custom-field-data-only-when-fields-are-true#post-22086 Wed, 29 Jun 2011 21:26:53 +0000 helgatheviking 22086@http://themeshaper.com/forums/ "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 $sponsortext exists <pre><code>function add_after_content($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 .= ''. $sponsortext.''; $sponsor .= 'For more information visit the website, <a href="http://'.$sponsorlink.'>" target="_blank">http://'.$sponsorlink.'</a>'; $sponsor .= '</div>'; $content .= $sponsor ; } return $content; } add_filter('the_content', add_after_content);</code></pre> 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. candregg on "Add post_meta custom field data only when fields are true" http://themeshaper.com/forums/topic/add-post_meta-custom-field-data-only-when-fields-are-true#post-22084 Wed, 29 Jun 2011 20:58:55 +0000 candregg 22084@http://themeshaper.com/forums/ 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: <pre><code>// 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"> <?php echo $sponsortext; ?> For more information visit the website, <a href="http://<?php echo $sponsorlink; ?>" target="_blank">http://<?php echo $sponsorlink; ?></a> </div> </div> <?php thematic_postfooter(); ?> </div> <?php endwhile; } add_action('thematic_categoryloop', 'child_category_loop'); add_action('thematic_archiveloop', 'child_category_loop');</code></pre> This code works great for the one category page, <a href="http://seacliffmm.com/prod/centurion/category/clients-testimonials/," rel="nofollow">http://seacliffmm.com/prod/centurion/category/clients-testimonials/,</a> But not for the general blog category page, <a href="http://seacliffmm.com/prod/centurion/category/news/" rel="nofollow">http://seacliffmm.com/prod/centurion/category/news/</a> 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.
