Posted 2021-05-04

// Make sortable
add_filter( 'manage_edit-product_sortable_columns', 'sortable_number' );
function sortable_number( $columns ) {
  $columns['number'] = 'number';
  return $columns;
}

// sort by NUMBER query
add_action( 'pre_get_posts', 'services_number_orderby' );
function services_number_orderby( $query ) {
    if( ! is_admin() )
        return;

    $orderby = $query->get( 'orderby');

    if( 'number' == $orderby ) {
        $query->set('meta_key','number');
        $query->set('orderby','meta_value_num');
    }
}
