I have written the following query to fetch a list and want to show the list of names in ascending order.

I was earlier trying to pass meta_key and meta_value as arguments but it would not give the sorting correctly.

After trying meta_query I'm still stuck with the same problem.

$connected = new WP_Query(
        'connected_type'    => 'posts_to_pages',
        'connected_items'   => get_queried_object(),
        'nopaging'          => true,
        'post_type'         => 'attorney',
        'attorney_category' => 'partner',
        'post_status'       => 'publish',
        'posts_per_page'    => - 1,
        'caller_get_posts'  => 1,
        'orderby'           => 'order_clause',
        'order'             => 'ASC',
        'meta_query'        => array(
            'order_clause' => array(
                'key' => 'Last name',

The following is the error I get when I print the query result:

  • Are you sure the key name you used is correct: "Last name"? Or is it something like wpcf-last-name? Please check in database - wp_postmeta table. Jun 19, 2017 at 18:59
  • yeah i checked in database and key name is proper.

I don't believe order_clause is an acceptable orderby parameter. According to the documentation you will need to add a meta_key to your query if you want to orderby a meta_value.

I have amended your query to display attorney posts where the custom field key Last name is present regardless of the custom field value. orderby is set to meta_value which refers to the meta_key which has been set to Last name.

$connected = new WP_Query(
    'connected_type' => 'posts_to_pages',
    'connected_items' => get_queried_object(),
    'nopaging' => true,
    'post_type' => 'attorney',
    'attorney_category'=> 'partner',
    'post_status' => 'publish',
    'posts_per_page' => -1,
    'caller_get_posts'=> 1,
    'meta_key'  => 'Last name',
    'orderby' => 'meta_value title',
    'order' => 'ASC',

Presuming your custom field is actually called Last name this query should work.

You could add a second orderby parameter such as title as a fallback:

'orderby' => 'meta_value title'
