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) {
    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'];

                '#title' => t('Relationship'),
