function views_plugin_display::unpack_handler

Special method to unpack items that have handlers.

This method was specified in the option_definition() as the method to utilize to export fields, filters, sort criteria, relationships and arguments. This passes the export off to the individual handlers so that they can export themselves properly.

Code

public function unpack_handler(&$translatable, $storage, $option, $definition, $parents) {
    $output = '';
    // Cut the 's' off because the data is stored as the plural form but we need
    // the singular form.
    if ($option != 'header' && $option != 'footer' && $option != 'empty') {
        $type = substr($option, 0, -1);
    }
    else {
        $type = $option;
    }
    $types = views_object_types();
    foreach ($storage[$option] as $info) {
        if (!empty($types[$type]['type'])) {
            $handler_type = $types[$type]['type'];
        }
        else {
            $handler_type = $type;
        }
        $handler = views_get_handler($info['table'], $info['field'], $handler_type);
        if ($handler) {
            $handler->init($this->view, $info);
            $items = array_merge($parents, array(
                $type,
                $info['table'],
                $info['id'],
            ));
