Description
I added a picture gallery to WP and wanted to be able to add to my posts a reference to the related picture category. I figured that adding custom tags to the post would be the best way to do it. Then, I needed them processed so I added a filter to the the_meta() function.
I followed the instructions on how to add a patch, but right now, I don't see a way to attach the patch, so here it goes in source form:
Index: wp-includes/post-template.php =================================================================== --- wp-includes/post-template.php (revision 3923) +++ wp-includes/post-template.php (working copy) @@ -212,7 +212,7 @@ continue; $values = array_map('trim', get_post_custom_values($key)); $value = implode($values,', '); - echo "<li><span class='post-meta-key'>$key:</span> $value</li>\n"; + echo apply_filters('custom_tags',"<li><span class='post-meta-key'>$key:</span> $value</li>\n",$key,$value); } echo "</ul>\n"; }
As for how it is used, this is the code that I added to my picture gallery. I used Photopress as the basis for my gallery, but I modified it so the code as shown is unusable with the original distribution, it is just an example.
add_filter('custom_tags','photopress_custom_tags_process',10,3); function photopress_custom_tags_process($custom_tag,$key,$value) { // sample: <li><span class='post-meta-key'>$key:</span> $value</li>\n switch($key) { case 'photopress_cat': return '<li><a href="?pp_album=main&pp_cat=' . intval($value) . '">' . __('Photos','photopress') . '</a></li>'; case 'photopress_image': $args=explode(',',$value); return '<li><a href="?pp_album=main&pp_cat=' . intval($args[0]) . '&pp_image=' . intval($args[1]). '">' . __('Photo','photopress') . '</a></li>'; default: return $custom_tag; } }

This is a nice idea. It'd be difficult for multiple plugins to play nice together here. Still, it's pretty convenient.
I attached a similar patch that calls the filter the_meta_key
. It's a bit more descriptive (though not perfect).
the_meta_key
