Hi,
heres what I am trying to do. Been trying to do it in SSH or PHP as I don't have KVM or physical access to the server.

1. get my server to browse to uploadmirrors.com
2. get it to click browse and select a file, mysqlbackup53.tar.gz
3. get it to click upload.

relevant code is

the browse button code is

 
 <form name="form_upload" id="form_upload" method="post" enctype="multipart/form-data" action="#" style="margin: 0px; padding: 0px;">

and upload button is

<input src="/images/uploadbtn.gif" id="upload_button" name="upload_button" value="Upload" onclick="linkUpload();" type="image">

if anybody has any ideas on how to do this I would be very grateful

You can't browse to sites and click buttons with php. You need some kind of program that you install on your computer that allows you to run macros to control the mouse and key inputs.

Or perhaps you can manually send tcp/ip headers and your file to the same address the form is sent, just like the browser does when you click the submit button. But I dont know if that's evan possible with php...

Not exactly, but you can mimic it.

For that, you need to use the Curl library (with PHP), and a request sniffer (like httpfox in firefox: https://addons.mozilla.org/en-US/firefox/addon/6647).

Go to the site you want to use, and copy, for each link you follow, which request is sent to the server (get or post).
You can see those requests and answers with httpfox.
Like:
open page www.site.com => GET http://site.com/index.php
upload the file => POST http://site.com/upload.php
show comfirm => GET http://site.com/thanks.php

Just filter what is local (IE an action => the file selection and the links/buttons click) and what is remote (IE an answer => the sending of datas back after an action)

Once you have the complete path, with the parameters sent on each requests, you can use Curl to build programmaticaly the same sequence.
