A GROUP BY statement can group your posts after the JOIN. For WordPress you can use the posts_groupby filter. add_filter( ‘posts_groupby’, ‘my_post_limits’ ); function my_post_limits($groupby) { global $pagenow, $wpdb; if ( is_admin() && $pagenow == ‘edit.php’ && $_GET[‘post_type’]==’listings’ && $_GET[‘s’] != ” ) { $groupby = “$wpdb->posts.ID”; } return $groupby; }
get_the_ID() returns the ID of the current post by way of get_post. Get post assumes the current post to be the global variable $post unless passed parameters specifying otherwise. That means that get_the_ID() should return the same value as contained in $post->ID. Using get_the_ID() lets you avoid dealing with the global directly, though you are … Read more
Excellent responses on WP Hackers: http://lists.automattic.com/pipermail/wp-hackers/2012-June/043213.html What you’re doing with that query, is loading EVERY matching post into memory, including the full post contents. As you can imagine, this is probably quite a lot of items. You can pass ‘fields’ => ‘ids’ into WP_Query to simply return a list of matching post_ids instead, which should … Read more

I would only increase the version number if users needed to download the plugin again. The “Tested up to” variable is not used when the plugin is installed, only when people want to install it or want to upgrade. In that case, the information comes from the server anyway, so you don’t need to force … Read more

Custom UI is great where it improves the experience and makes the task easier. After all, a plugin extends WordPress and therefore a lot of the time is extending the user interface. This might mean a screen that is arranged completely differently to any other screen, but if it is logical and understandable then there’s … Read more
get_bloginfo(‘url’) calls home_url() calls get_home_url() reads option home get_bloginfo(‘wpurl’) calls site_url() calls get_site_url() reads option siteurl get_bloginfo(‘siteurl’) and get_bloginfo(‘home’) are deprecated arguments and return get_bloginfo(‘url’) (siteurl argument is documented wrong in Codex as equal to wpurl, it’s not in current code) The difference is that these two function chain to different options, which are typically … Read more
