Drupal 5: Sending a CCK node in an HTML email when its created using PEAR libraries

Although I am a big fan of the Drupal Forms API, sometimes I'll use CCK node forms as a quick and flexible alternative. This allows you to store the user submitted data as well as process the form. Here is a code snippet you can add to send the html generated from the node in an HTML email:

<?php
function MYMODULE_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL) {
  if ($node->type == 'MYNODETYPE' && $op=='insert') {
    $emailTo = variable_get('site_mail', 'MYEMAILADDRESS');
    $emailFrom = 'info@' . $_SERVER['HTTP_HOST'];

    // send email
    _MYMODULE_send_node_email($node, $emailTo, $emailFrom);

  }

}

function _MYMODULE_send_node_email(&$node, $emailTo, $emailFrom) {

  require_once('Mail.php');
  require_once('Mail/mime.php');

  // create node html
  $html = node_view($node, TRUE, FALSE, FALSE);

  // get a list of node types
  $nodeTypes = node_get_types();

  $crlf = "\n";
  $hdrs = array(
    'From'    => $emailFrom,
    'Subject' => $nodeTypes[$node->type]->name . ' Submitted',
  );

  $mime = new Mail_mime($crlf);
  //$mime->setTXTBody($text);  //TODO: you should also include a text version of your email
  $mime->setHTMLBody($html);
  $body = $mime->get();
  $hdrs = $mime->headers($hdrs);
  $mail =& Mail::factory('mail');
  $mail->send($emailTo, $hdrs, $body);

}
?>
