我正在尝试开发一个模块来一次插入很多节点，我想使用 Batch-API 来显示操作的进度。

我将示例读入“示例”模块并编写了此代码。

但不要做任何事。我可以看到进度条往前走，但它不保存任何节点。

谁可以帮我这个事？

function custom_content_archive_import_contents_submit($form, &$form_state) {
    $file=$form_state['values']['file'];
    unset($form_state['values']['file']);
    $file->status = FILE_STATUS_PERMANENT;
    file_save($file);
    drupal_set_message(t('The file @filename was uploaded successfully.', array('@filename' => $file->filename)));

    ini_set('auto_detect_line_endings',TRUE);
    $path = drupal_realpath($file->uri);
    $importer = new CsvImporter($path, true, variable_get('custom_content_archive_file_delimiter'), variable_get('custom_content_archive_file_enclosure'));
    $data = $importer->get();
    ini_set('auto_detect_line_endings',FALSE);

    $_SESSION['http_request_count'] = 0; // reset counter for debug information.
    $all_data = array(
        'ctype' => $form_state['values']['list'],
        'data' => $data,
        'user' => $form_state['values']['user'],
        'lang' => $form_state['values']['languages'],
    );
    batch_set(start_batch_creation_nodes($all_data));
}

function start_batch_creation_nodes($all_data) {
    $num_operations = count($all_data['data']);

    $operations = array();
    $i = 0;
    // leggo il file uploadato e creo i nodi
    foreach ($all_data['data'] as $node) {
         $operations[] = array('create_node', 
                          array($node,
                                $all_data['ctype'],
                                $all_data['user'],
                                $all_data['lang'],
                                t('(Operation @operation)', array('@operation' => $i))
                          )
         );
         $i++;
    }

    $batch = array(

    return $batch;

    $node = new stdClass(); // Create a new node object
    $node->type = $ctype; // Or page, or whatever content type you like
    node_object_prepare($node); // Set some default values
    $node->uid = $user; // UID of the author of the node; or use $node->name
    $node->language = $lang; // Or e.g. 'en' if locale is enabled
    $node->promote = 0;

您必须在函数中包含 node.pages.inc 才能使 node_object_prepare() 工作。

module_load_include('inc', 'node', 'node.pages');
