Class

views_plugin_row

Default plugin to view a single row of a table. This is really just a wrapper around a theme function.

Code

function options_form(&$form, &$form_state) {
  parent::options_form($form, $form_state);
  if (isset($this->base_table)) {
    $view = &$form_state['view'];

    // A whole bunch of code to figure out what relationships are valid for
    // this item.
    $relationships = $view->display_handler->get_option('relationships');
    $relationship_options = array();

    foreach ($relationships as $relationship) {
      $relationship_handler = views_get_handler($relationship['table'], $relationship['field'], 'relationship');

      // If this relationship is valid for this type, add it to the list.
      $data = views_fetch_data($relationship['table']);
      $base = $data[$relationship['field']]['relationship']['base'];
      if ($base == $this->base_table) {
        $relationship_handler->init($view, $relationship);
        $relationship_options[$relationship['id']] = $relationship_handler->label();
      }
    }

    if (!empty($relationship_options)) {
      $relationship_options = array_merge(array('none' => t('Do not use a relationship')), $relationship_options);
      $rel = empty($this->options['relationship']) ? 'none' : $this->options['relationship'];
      if (empty($relationship_options[$rel])) {
        // Pick the first relationship.
        $rel = key($relationship_options);
      }

      $form['relationship'] = array(
        '#type' => 'select',
        '#title' => t('Relationship'),
        '#options' => $relationship_options,
        '#default_value' => $rel,
      );
    }
    else {
      $form['relationship'] = array(
        '#type' => 'value',
        '#value' => 'none',
      );
    }
  }
