Upload file to front-end form and send as email attachment

Question

I am trying to create a front-end form that has an option to upload a CV (so pdf or word format) that I would like to be able to send as an email attachment. I've read a few articles and tutorials the most pertinent (link to article) which suggests something like this:

<?php
if ($_FILES) {
  foreach ($_FILES as $file => $array) {
  $newupload = insert_attachment($file,$post_id);
  //in this case ('upload_file', 'null')
  }
}
?>

<form method="post" action="<?php the_permalink(); ?>" enctype="multipart/form-data" >
  <input type="file" name="upload_file">
  <input type="submit">
<form>

In functions php:

function insert_attachment($file_handler,$post_id, $setthumb='false') {

  // check to make sure its a successful upload
  if ($_FILES[$file_handler]['error'] !== UPLOAD_ERR_OK) __return_false();

  require_once(ABSPATH . "wp-admin" . '/includes/image.php');
  require_once(ABSPATH . "wp-admin" . '/includes/file.php');
  require_once(ABSPATH . "wp-admin" . '/includes/media.php');

  $attach_id = media_handle_upload( $file_handler, $post_id );

  return $attach_id;
 }

The problem is that this uploads the CV to the media library which I don't really want. I have put the rest of the code concerning the form here

How could I take $newupload and attach to to an email? (Ideally in the form of an attachment)

Answer 1

The problem is that this uploads the CV to the media library which I don't really want.

Instead of using media_handle_upload, try wp_handle_upload.

WordPress provides us with a wp_mail through which you can easily send an email with an attachment
