Description

Post content and a file using wp_remote_post()

Implement RFC2388 to post a file to a WordPress server along with other data We want to create/update an attachment in a single request. The intention is to use wp_remote_post() to post a multipart/form-data with

• the original body as one part
• the file as another
• additional fields to make it work at the server end

Each multipart is of the general form: boundary

--boundary Content-Disposition: form-data; name="file"; filename="example.ext" ` 

value 

There is a trailing boundary record

--boundary-- 

Where:

• The boundary field that separates the parts is defined in the Content-Type header
• When sending a file we include the filename= keyword.
• Data is just named with the appropriate field name
• Each line ends with \r\n
• The overall Content-Length is the length of the 'body' that's created from each of the parts

The following notes could be due to programming issues:

• File content is received as passed. If you base64 encode it on the client end it needs to be decoded on the server
• Get it slightly wrong and Apache mod_security may return an HTTP 403
