Batch-API: what am I doing wrong in this code? - php

Question

I am trying to develop a module to insert a lot of node at one time and I would like to use Batch-API to display the progress of operations.
I read the example into 'Example' module and I wrote this code.
But don't made anything. I can see the progress bar go head but it don't save any node.
Can anyone help me on this?
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));
}

You have to include node.pages.inc in your function to make node_object_prepare() work.
module_load_include('inc', 'node', 'node.pages');
