I’m trying to create a batch to import users. I used this (http://pastebin.com/duTbxpgd) as an example, but somehow it’s not working. I see the progress bar advancing and It’s showing the right number of rows I’m processing. But what I’m trying to do in the operation function isn’t executed.

Here’s my code:

function form_submit($form, &$form_state) {   batch_import_users(); }  function batch_import_users() {   db_set_active('mysqldb');    $result = db_query("SELECT * FROM {users}");    db_set_active('default');    $batch = array(     'title' => t('Importing users ...'),     'operations' => array(),     'init_message' => t('Commencing'),     'progress_message' => t('Processed @current out of @total.'),     'error_message' => t('An error occurred during processing'),     'finished' => 'batch_import_users_finished',     'progressive' => FALSE,     'file' => 'users.inc',   );    foreach ($result as $row) {     $batch['operations'][] = array('batch_create_user', array($row));   }    batch_set($batch);    batch_process(); }  function batch_create_user($row, &$context) {   // Here I'm just trying to get some output so I know the operation is called, I'm not actually importing the users yet.    drupal_set_message($row->uid . ' : ' . $row->login);   dd($row->uid . ' : ' . $row->login);    $context['results']['processed']++;   $context['message'] = $row->login; }  function batch_import_users_finished($success, $results, $operations) {   if ($success) {     drupal_set_message('Importing users has finished.');   }   else {     drupal_set_message('Some error.');   } } 

Am I missing something or doing something wrong? Any help is very much appreciated.
