You can do it with a posts_where filter and a subquery. Note that you have to explicitly set suppress_filters to false, as get_posts normally ignores filters: function wpse28018_posts_where( $where ) { global $wpdb; $where .= ” AND {$wpdb->posts}.ID NOT IN ( SELECT DISTINCT post_id FROM {$wpdb->postmeta} WHERE meta_key = ‘alternate_page’ )”; return $where; } // … Read more
Short answer: no. Shortcodes are for injecting content directly in the Post Content, by the user, via the Post Edit screen. If your data are coming from a metabox, you have other, better, more efficient, and easier-to-control means of injecting content into the Post Content: primarily, the the_content filter (for general usage), or custom action … Read more

You just need to write a delete avatar function that gets the location of the file and deletes it using the php unlink function. The following code can be used as an example of how it’s done. I use this to delete the old user avatars when a user uploads a new one. It is … Read more
I haven’t touched user functions so far, but according to the codex, should look something like this. $args = array( ‘meta_key’ => ‘g300’, ‘meta_value’ => ‘,’ ); $users = get_users( $args ); EDIT This assumes that all the users with the field unchecked have a comma value ( for example, it won’t work if the … Read more
