Class

views_handler_sort_ncs_last_comment_name

Sort handler to sort by last comment name which might be in 2 different fields

Code

function query() {
  $this
    ->ensure_my_table();
  $join = new views_join();
  $join
    ->construct('users', $this->table_alias, 'last_comment_uid', 'uid');

  // @todo this might be safer if we had an ensure_relationship rather than guessing
  // the table alias. Though if we did that we'd be guessing the relationship name
  // so that doesn't matter that much.
  //    $this->user_table = $this->query->add_relationship(NULL, $join, 'users', $this->relationship);
  $this->user_table = $this->query
    ->ensure_table('ncs_users', $this->relationship, $join);
  $this->user_field = $this->query
    ->add_field($this->user_table, 'name');

  // Add the field.
  $this->query
    ->add_orderby(NULL, "LOWER(COALESCE({$this->user_table}.name, {$this->table_alias}.{$this->field}))", $this->options['order'], $this->table_alias . '_' . $this->field);
}
