Love this plugin, but one little bug, if you are using an external object cache (like APC or Memcache) and you look at your posts list and see a missing featured image, then you add one, the list still shows that you don’t have a featured image (or if you change one it shows the old). This is due to caching. I created this simple function for my functions file to solve it. It’d be great if you can integrate this into your code:<\/p>\n
\/***
\n*
\n* ADMIN: Clear cache for featured image column plugin when new featured image
\n* only useful as long as featured image column plugin is active
\n* could be a conditional to check if meta_key=_thumbnail_id, but figured the lookup isn’t worth it, just delete the cache on all post meta updates for a post
\n*
\n****\/<\/p>\n
function fic_thumbnail_updated_actions($meta_id, $post_id) {<\/p>\n
\t$post_id\t= (int) $post_id;
\n\t$cache_key\t= “featured_image_post_id-{$post_id}-_thumbnail”;
\n\t$cache\t\t= wp_cache_delete( $cache_key, null );<\/p>\n
