Class

views_handler_argument_many_to_one

An argument handler for use in fields that have a many to one relationship with the table(s) to the left. This adds a bunch of options that are reasonably common with this type of relationship. Definition terms:

Code

function query() {
  $empty = FALSE;
  if (isset($this->definition['zero is null']) && $this->definition['zero is null']) {
    if (empty($this->argument)) {
      $empty = TRUE;
    }
  }
  else {
    if (!isset($this->argument)) {
      $empty = TRUE;
    }
  }
  if ($empty) {
    parent::ensure_my_table();
    $this->query
      ->add_where(0, "{$this->table_alias}.{$this->real_field} IS NULL");
    return;
  }
  if (!empty($this->options['break_phrase'])) {
    views_break_phrase($this->argument, $this);
  }
  else {
    $this->value = array(
      $this->argument,
    );
    $this->operator = 'or';
  }
  $this->helper
    ->add_filter();
}
