Re: Retrieve attachment from a Post - mailgun

I just responded, but I  should have reiterated the flow the the application.   It's basically as follows:

1.  I send an email to mailgun
2.  Mailgun parses the message and POSTS it to my web page/controller over HTTP
3.  My application has a single controller (no models or views) with one method that currently only does this:
$this->log($this->request->data);
4.  I found a Ruby sample that seems to deal with this, but Cakephp is not.  I am wondering if the cake request object is not handling the FILES correctly. Here is that sample:

      # enumerate through all attachments in the message and save      # them to disk with their original filenames:      for attachment in request.files.values():          attachment.filename          data = attachment.stream.read()          with open(attachment.filename, "w") as f:              f.write(data)
5.  Here is some additional information on the attachment fields from mailgun.

attachment-x string attached file ('x' stands for number of the attachment). Attachments are handled as file uploads, encoded as multipart/form-data.
content-id-map string JSON-encoded dictionary which maps Content-ID (CID) of each attachment to the corresponding attachment-x parameter. This allows you to map posted attachments to tags like <img src='cid'> in the message body.

6.   Here is a dump of the request object received when a new message is received.  Note that the [content-id-map] and [attachment-count] are both there.   The [attachment-1] is also referenced in the [content-id-map]

That will either answer the question for you or show the data isn't there to be accessed.

hi there - hoping someone can help me with a simple issue I have having with retrieving data from an HTTP Post.   I am using mailgun to post an email message to a simple method in my application...  Everything is working correctly except I can't get attachments out of the POST.  I noticed that the encoding is set as multipart/form-data and the support guys at mailgun indicated I had to use $FILES to retrieve the data from the post.   I am a bit of a newbie, so now I am lost..

Here is what my current code looks like:

$subject = $this->request->data('subject');   //THIS WORKS

$attachement_test1 = $this->request->data($_FILES['attachment-1']);  //THIS DOESN'T WORK

$attachement_test2 = $this->request->data('attachment-1');//THIS DOESN'T WORK EITHER

$this->log("New Message");

$this->log($subject);

$this->log($attachement_test1);

$this->log($attachement_test2);


Snip from the mailgun docs:


attachment-x string attached file ('x' stands for number of the attachment). Attachments are handled as file uploads, encoded as multipart/form-data.
