Attachment sent as encoded text - php

Question

I am trying to forward the attachment sin my email to another account automatically using this script and swift mailer library. Thing seems to be working for certain extent but the attachments are sent as encoded text. I wanted to send the attachments as it is. I am new to php and unable to figure out where the issue is. Please help me.
<?php

Answer 1

What is $data after $data = $result['attachments'];? Think it is an attachment container object of some sort. You might need to dig in a little more to get the right property (the attachment) to then reattach it. See: http://dev.kayako.com/browse/SWIFT-2341

Answer 2

This doesn't look right:
$data = $result['attachments'];
...
$attachment = Swift_Attachment::newInstance($data, 'recorded.mp3', 'audio/mp3');
When you create an attachment with this method, I think $data is supposed to be a string that contains the contents of the attachment. But $result['attachments'] is an array of all the attachments in the original message. It seems like you should be looping through these attachments, creating a separate Swift_Attachment for each of them. You also should save the filename and content type from the original message, not hard-code them to recorded.mp3 and audio/mp3 (unless the application ensures that this is all there will be).
As for them being encoded -- MP3's aren't plain text, so what do you expect?
