[development] E-mail sending attachment

[Muzaffer Tolga Ozses]

Hi,

I've been trying to develop this module. It does what I need, with the
exception of e-mailing a PDF file. What is wrong with my code? It gives me
'Undefined variable $attachment' and doesn't e-mail the attachment.

function pass2pdf_email_pdf_to_user($form) {
  global $user;
  $account = $user;
  require(libraries_get_path('fpdf') . '/fpdf.php');
  $pdf = new FPDF();
  $pdf->AddPage();
  $pdf->SetFont('Arial', 'B', 16);
  $pdf->Image(theme_get_setting('logo'), 10, 6, 30);
  $pdf->Cell(100, 100, $form['pass2pdf_pass']['#value']['pass1']);
  $pdf->Output(drupal_realpath('public://') . '/' .
$form['account']['name']['#value'] . '.pdf');
  $to = $form['account']['mail']['#value'];
  $from = variable_get('site_name') . "<" . variable_get('site_mail') . ">";
  $subject = t('Your password from @site', array('@site' =>
variable_get('site_name')));
  $body = t('Hello !user. Please find your password in the attached PDF
file.', array('!user' => $form['account']['name']['#value']));
  $attachment = array(
    'filecontent' => file_get_contents(drupal_realpath('public://') . '/'.
$form['account']['name']['#value'] . '.pdf'),
    'filemime' => 'application/pdf',
  );
  $params['subject'] = $subject;
  $params['body'] = $body;
  $params['attachment'] = $attachment;
  $message = drupal_mail('pass2pdf', 'key', $to,
user_preferred_language($user), $params, $from, TRUE);
  if ($message) {
    drupal_set_message(t('E-mail sent successfully'));
  }
}

function pass2pdf_mail($key, &$message, $attachment) {
  switch($key) {
    case 'key':
      $message['subject'] = $subject;
      $message['body'][] = $body;
      $message['attachments'][] = $attachment;
      break;
  }
}

Regards,
