Class

views_handler_field_ncs_last_comment_name
Field handler to present the name of the last comment poster.

Code

function query() {
  // last_comment_name only contains data if the user is anonymous. So we
  // have to join in a specially related user table.
  $this->ensure_my_table();
  // join 'users' to this table via vid
  $join = new views_join();
  $join->construct('users', $this->table_alias, 'last_comment_uid', 'uid');
  $join->extra = array(array('field' => 'uid', 'operator' => '!=', 'value' => '0'));

  // ncs_user alias so this can work with the sort handler, below.
  //    $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->field_alias = $this->query->add_field(NULL, "COALESCE($this->user_table.name, $this->table_alias.$this->field)", $this->table_alias . '_' . $this->field);

  $this->user_field = $this->query->add_field($this->user_table, 'name');
  $this->uid = $this->query->add_field($this->table_alias, 'last_comment_uid');
