Definition of views_handler_argument_many_to_one.

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($group_by = FALSE) {
  $empty = FALSE;
  if (isset($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", NULL, '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();
}
