You can pass an array to the query as the following example described in the Codex shows: $args = array( ‘orderby’ => array( ‘title’ => ‘DESC’, ‘menu_order’ => ‘ASC’ ) ); $query = new WP_Query( $args ); In your case will be something like this: /* Order Posts Alphabetically */ function prefix_modify_query_order( $query ) { … Read more
I modified some code from an old blog post to do this, and allow for query-strings to be attached to the file as well. Original credit goes to amberpanther.com, and it turns out they made a plug-in out of this, too. //create the shortcode [include] that accepts a filepath and query string //this function was … Read more
A long time ago WordPress did not put feed links into the head element automatically. Theme or plugin authors had to do that. In 2009 automatic_feed_links() was introduced, a function that should be used in themes or plugins to let WordPress do the hard work. One year later it was added to Twenty Ten, and … Read more
The save_post action fires When a post is updated and/or published — including when a new post is inserted. <?php add_action( ‘save_post’, ‘wpse41912_save_post’ ); function wpse41912_save_post() { // do stuff } If you want your functions to fire only when a post is being edited, you can hook into edit_post.

The correct way is to pass first argument as a unique string which acts as an identifier for the action & any additional arguments after that do_action(‘unique_action_tag’, $parameter1, $parameter2,,,, & so on); To attach functions to this action you’ll do // 10 is the priority, higher means executed first // 2 is number of arguments … Read more
I guess you mean add_action( ‘pre_get_posts’, ‘private_groups’ ); add_action( ‘pre_get_posts’, ‘search_results’ ); add_action( ‘pre_get_posts’, ‘name_profiles’ ); versus add_action( ‘pre_get_posts’, ‘combined_into_single_callback’ ); You can just check the difference using e.g. memory_get_usage() and timer_stop(). Many good plugins out there to help with that. I would say go with the first one, as they seems to be unrelated … Read more
Maybe you can try adding your condition directly in the query string, using something like this function wpse_29570_where_filter($where){ global $wpdb; if( is_search() ) { $search= get_query_var(‘s’); $query=$wpdb->prepare(“SELECT user_id FROM $wpdb->usermeta WHERE ( meta_key=’first_name’ AND meta_value LIKE ‘%%%s%%’ ) or ( meta_key=’last_name’ AND meta_value LIKE ‘%%%s%%’ )”, $search ,$search); $authorID= $wpdb->get_var( $query ); if($authorID){ $where = … Read more
WordPress read the templates from file headers, and then set them in the cache. using wp_cache_set() nad a key that is derived from the md5 has of stylesheet folder.

The admin_url() function retrieves the URL to the admin area for your current site. You needn’t give the blog id for your current site. You can use this function if you aren’t running WordPress multisite. And use the get_admin_url() function to get a specific site URL in the multisite admin.
