If you want to get a post with meta key show_on_homepage and meta value on, you can do it in the following way: $rd_args = array( 'meta_key' => 'show_on_homepage', 'meta_value' => 'on' ); $rd_query = new WP_Query($rd_args); If you need to query all posts except the ones with this pair of meta key and value, you can use the following parameters: $rd_args = array( 'meta_key' => 'show_on_homepage', 'meta_value' => 'on', 'meta_compare' => '!=' ); $rd_query = new WP_Query( $rd_args ); Get Posts with a Specific Custom Field Value // the meta_key 'color' with the meta_value 'white' $rd_args = array( 'meta_query' => array( array( 'key' => 'color', 'value' => 'white' ) ) ); $rd_query = new WP_Query( $rd_args ); Get all the posts except the ones with meta key «color» and meta value «white»: $rd_args = array( 'meta_query' => array( array( 'key' => 'color', 'value' => 'white', 'compare' => '!=' ) ) ); $rd_query = new WP_Query( $rd_args ); Get all the posts with white OR green color custom field value: // custom field name is color and custom field value is 'white' OR 'green' $rd_args = array( 'meta_query' => array( array( 'key' => 'color', 'value' => array('white','green'), 'compare' => 'IN' ) ) ); $rd_query = new WP_Query( $rd_args ); Get all the posts (products in online shop for example) except white products and green products: $rd_args = array( 'meta_query' => array( array( 'key' => 'color', 'value' => array('white','green'), 'compare' => 'NOT IN' ) ) ); $rd_query = new WP_Query( $rd_args ); Get Posts Within a Given Range of Numeric Meta Values // the product price is more than 2000...

Here are few wordpres hacks that are very usefull while developing wordpress plugins and themes. Hide wordpress adminbar add_action('init', 'remove_admin_bar'); function remove_admin_bar() { if ( !current_user_can('administrator') && !is_admin()) { show_admin_bar(false); } } Show user/author posts only in admin By default wordpress displays all posts for any user logged into wp-admin. The following code restricts the post list by displaying only his posts. function wps_get_post_list_by_user($clauses) { if (is_admin()) { global $user_ID, $wpdb; // $clauses['join'] = ", wp_posts"; $clauses['where'] .= " AND wp_posts.post_author = ".$user_ID; }; return $clauses; }; if ( !current_user_can( 'edit_users' ) ) { add_filter('posts_clauses', 'wps_get_post_list_by_user'); } Remove unwanted admin menus function remove_admin_menu_items() { $remove_menu_items = array(__('Links'), __('Dashboard'), __('Media'), __('Links'), __('Appearance'), __('Tools'), __('Settings'), __('Comments'), ); global $menu; end ($menu); while (prev($menu)){ $item = explode(' ',$menu[key($menu)][0]); if(in_array($item[0] != NULL?$item[0]:"" , $remove_menu_items)){ unset($menu[key($menu)]);} } } if(get_logged_user_role()!="administrator"){ add_action('admin_menu', 'remove_admin_menu_items'); } Set Post Expert Length function custom_excerpt_length( $length ) { return 100; } add_filter( 'excerpt_length', 'custom_excerpt_length', 999 ); Hide Plugin Update Notifications just copy and paste that code in the .php file of the plugin add_filter('site_transient_update_plugins', 'dd_remove_update_nag'); function dd_remove_update_nag($value) { unset($value->response[ plugin_basename(__FILE__) ]); return $value;...
