使用WP_User_Query进行名字和姓氏搜索

Question

I am trying to develop a directory search. The following works fine for last name search with like. But, I need last and first name to search together. How can I make that happen:

function dispDirectory()
{
  global $user_ID;

  // Disallow directory if there is a messaging administrator and this person is not it.
  if ($this->admin_user_id && $this->admin_user_id != $user_ID) {
    return '';
  }

    $directory = "<form name='form' method='post'><label for='clientname'>Client Name: </label>
    <input name='clientname' id='clientname' type='text' style='width: 181px;'
    value=''/><input type='submit'></form>";

    $clientname= $_POST["clientname"];

    $search_string = $clientname;

    $args  = array(
        'meta_key' => 'last_name',
        'meta_compare' => 'like',
        'meta_value' => $search_string,
    );

    $wp_user_query = new WP_User_Query($args);
    $wp_user_query->query_orderby = str_replace( 'user_login', 'wp_usermeta.meta_value', $wp_user_query->query_orderby );
    $wp_user_query->query();

    $users = $wp_user_query->get_results();


  foreach($users as $u)
  {
    $firstName = get_user_meta($u->ID, 'first_name', true);
    $lastName = get_user_meta($u->ID, 'last_name', true);         

    $directory .= '<p><strong>'.$lastName.', '.$firstName.'</strong> - <a href="'.$this->actionURL.'newmessage&to='.$u->ID.'">'.__('Send Message', 'cartpaujpm').'</a></p>';
  }
  return $directory;
}

You can search by multiple meta fields like below meta query,

$args  =  array ( 
        'meta_query' => array(
        'relation' => 'OR',
        array(
            'key'     => 'first_name',
            'value'   => $search_string,
            'compare' => 'LIKE'
        ),
        array(
            'key'     => 'last_name',
            'value'   => $search_string,
            'compare' => 'LIKE'
        )
        )
    );
