How to fix hook for FormIt?

Question

MODX

There is a task so that when submitting a completed form, a file is downloaded, and then the user is redirected to another page. The file is loaded through the TV-field. I'm trying to do it with the download
hook :

$kp = $_SERVER['DOCUMENT_ROOT'];
  $kp .= $modx->resource->getTVValue('kp');

  if (file_exists($kp)) {
      header('Content-Description: File Transfer');
      header('Content-Type: application/octet-stream');
      header('Content-Disposition: attachment; filename="'.basename($kp).'"');
      header('Expires: 0');
      header('Cache-Control: must-revalidate');
      header('Pragma: public');
      header('Content-Length: ' . filesize($kp));
      readfile($kp);
      exit;
  } else {
    $modx->log(xPDO::LOG_LEVEL_ERROR, 'Нет такого файла');
  }
  return true;

I call FormIt as usual:

The problem is that the file is downloaded, but the redirect does not work. I suppose this is due to the exit function , but if you remove it (or put return true; instead ), then the redirect works, but the file does not download.
Can you tell me how to make both actions work?

Answer 1

remove redirect and try to put header with redirect manually before exit
