Send File Attachment from Form Using phpMailer and PHP

Question

I have a form on example.com/contact-us.php that looks like this (simplified):

<form method="post" action="process.php" enctype="multipart/form-data">
  <input type="file" name="uploaded_file" id="uploaded_file" />
  <input type="hidden" name="MAX_FILE_SIZE" value="10000000" />
</form>

In my process.php file, I have the following code utilizing PHPMailer() to send an email:

require("phpmailer.php");

$mail = new PHPMailer();

$mail->From     = me@example.com;
$mail->FromName = My name;
$mail->AddAddress(me@example.com,"John Doe");

$mail->WordWrap = 50;
$mail->IsHTML(true);

$mail->Subject  =  "Contact Form Submitted";
$mail->Body     =  "This is the body of the message.";

The email sends the body correctly, but without the Attachment of uploaded_file.

MY QUESTION

I need the file uploaded_file from the form to be attached to the email, and sent. I do NOT care about saving the file after the process.php script sends it in an email.

I understand that I need to add AddAttachment(); somewhere (I'm assuming under the Body line) for the attachment to be sent. But...

1. What do I put at the top of the process.php file to pull in the file uploaded_file? Like something using $_FILES['uploaded_file'] to pull in the file from the contact-us.php page?
2. What goes inside of AddAttachment(); for the file to be attached and sent along with the email and where does this code need to go?

Please help and provide code!Thanks!

Answer 1

Try:

if (isset($_FILES['uploaded_file'])
    && $_FILES['uploaded_file']['error'] == UPLOAD_ERR_OK
) {
    $mail->addAttachment($_FILES['uploaded_file']['tmp_name'],
                         $_FILES['uploaded_file']['name']);
}

A basic example attaching multiple file uploads can be found here.

The function definition for addAttachment is:

/**
 * Add an attachment from a path on the filesystem.
 * Never use a user-supplied path to a file!
 * Returns false if the file could not be found or read.
 * Explicitly *does not* support passing URLs; PHPMailer is not an HTTP client.
 * If you need to do that, fetch the resource yourself and pass it in via a local file or string.
 *
 * @param string $path        Path to the attachment
 * @param string $name        Overrides the attachment name
 * @param string $encoding    File encoding (see $Encoding)
 * @param string $type        MIME type, e.g. `image/jpeg`; determined automatically from $path if not specified
 * @param string $disposition Disposition to use
 *
 * @throws Exception
 *
 * @return bool
 */
public function addAttachment(
    $path,
    $name = '',
    $encoding = self::ENCODING_BASE64,
    $type = '',
    $disposition = 'attachment'
)
