File Upload Encoding

    I’m trying to setup a contact form which allows the user also to upload a file. But when I try the form I get totally weird Emails. I guess it’s something about the encoding of the uploaded file. It looks to me as if the file (here a DOCX) is not attached but encoded as text (base64). Any idea?

    Here’s a sample from the Email. The allowed file-types are: pdf,docx,doc,jpeg,jpg

    Thanks, Matthias

    This seems to be correct. Do you see this text in an email client (which one?) or do you see it as an attachment? If you do not see it as an attachment, please also paste some more parts of the email (including the MIME boundaries).

    Correct would be an Email with a file attached to it, right? Here’s more information on how I received the Email. We got a work around by storing the Email on the server but this is not what we prefer.
    The Email client is “Live Mail”.

    Content-Type: multipart/alternative;

    There should be somthing like

    Content-Type: multipart/mixed;
	boundary="xxx"

    in your mail header and some --xxx before your first line Content-Type: multipart/alternative;

    Additionally, there should be some --xxx befor your line Content-Type: application/octet-stream; name="noid-Mitgliedsantrag.docx" and some --xxx-- after the base64 encoded docx.

    By the way: emails have to use some binary to text conversion for attachments as they are text messages. base64 is the common conversion. So that is not a problem.

    How do you send the emails? Any additional plugin to use SMTP instead of PHP’s mail() function?
