I am trying to get a file to upload as part of a contact form, i would like the uploaded file to end up as an attachement to an email that i can then download once i have received said email. I have got the form to work but instead of coming through as an attachment my file comes through like this;

解决方案
Why dont you use Swift Mailer
Docs : Swift Mailer Documentation
Downloads : Swift-5.1.0
require_once 'lib/swift_required.php';
// Create the message
$message = Swift_Message::newInstance()
// Give the message a subject
->setSubject('Your subject')
// Set the From address with an associative array
->setFrom(array('john@doe.com' => 'John Doe'))
// Set the To addresses with an associative array
->setTo(array('receiver@domain.org', 'other@domain.org' => 'A name'))
// Give it a body
->setBody('Here is the message itself')
// And optionally an alternative body
->addPart('<q>Here is the message itself</q>', 'text/html')
// Optionally add any attachments
->attach(Swift_Attachment::fromPath('my-document.pdf'));
