Batch processing API for processes to run in multiple HTTP requests.

Code

function _batch_progress_page_nojs() {
  $batch = &batch_get();
  $current_set = _batch_current_set();

  drupal_set_title($current_set['title']);

  $new_op = 'do_nojs';

    // This is the first page so we return some output immediately.

    $message = $current_set['init_message'];
    $batch['running'] = TRUE;
  }
  else {
    // This is one of the later requests: do some processing first.

    // Error handling: if PHP dies due to a fatal error (e.g. non-existant
    // function), it will output whatever is in the output buffer,
    // followed by the error message.
    ob_start();
    $fallback = $current_set['error_message'] . '<br/>' . $batch['error_message'];

    // We strip the end of the page using a marker in the template, so any
    // additional HTML output by PHP shows up inside the page rather than
    // below it. While this causes invalid HTML, the same would be true if
    // we didn't, as content is not allowed to appear after </html> anyway.
    list($fallback) = explode('<!--partial-->', $fallback);
    print $fallback;

    // Perform actual processing.
    list($percentage, $message) = _batch_process($batch);
