使用方式如下：
batch_set(batch_example_batch_1());
batch_process('redirect_page.php');
function batch_example_batch_1() {
for ($i = 0; $i<100; $i++) {
$operations[] = array('batch_example_op_1', array($nid));
}
$batch = array(
'operations' => $operations,
'finished' => 'batch_example_finished',
);
return $batch;
}
function batch_example_op_1($nid, &$context) {
do_something();
// Store some result for post-processing in the finished callback.
$context['results'][] = "do something";
// Optional message displayed under the progressbar.
$context['message'] = t('Loading @title', array('@title' => $node->title));
}
function batch_example_finished($success, $results, $operations) {
if ($success) {
$message = count($results) . ' processed.';
}
else {
$error_operation = reset($operations);
$message = 'An error occurred while processing ' . $error_operation[0] . ' with arguments :' . print_r($error_operation[0], TRUE);
}
drupal_set_message($message);
batch_process('redirect_page.php');
function batch_example_batch_1() {
for ($i = 0; $i<100; $i++) {
$operations[] = array('batch_example_op_1', array($nid));
}
$batch = array(
'operations' => $operations,
'finished' => 'batch_example_finished',
);
return $batch;
}
function batch_example_op_1($nid, &$context) {
do_something();
// Store some result for post-processing in the finished callback.
$context['results'][] = "do something";
// Optional message displayed under the progressbar.
$context['message'] = t('Loading @title', array('@title' => $node->title));
}
function batch_example_finished($success, $results, $operations) {

$message = 'An error occurred while processing ' . $error_operation[0] . ' with arguments :' . print_r($error_operation[0], TRUE);
}
drupal_set_message($message);
