Submiting file to remote form

[manuman]

I am trying to submit a file to a form on a remote site.

This is to be done from with-in PHP. That is... my page writes a txt file, and must then automatically submit that file to the remote form for upload

Any ideas on how to do this would be appreciated.

Look on the internet for an explanation of the POST request of the HTTP specification. More specifically, the part dealing with file uploads. You'll see that you have to create a proper request header, attach the file (after encoding) and then open a socket to the remote server, send the request/file, and check the output. It sounds daunting, but because of HTTP, it's really quite simple and straight-forward.

If you proceed, some quick tips: check your mime-types and HTTP version 🙂 (I'd suggest using HTTP 1.0, and use the host header to maintain compatability with servers using name-based virtual hosts)
