POSTING from PHP

[elck]

print <<<end
<form enctype="multipart/form-data" action="[URL unfurl="true"]http://site.com/chessup.php"[/URL] method="post"  id="pform">
<input type="hidden" name="oldid" value=$oldid >
<input type="hidden" name="link" value=$link >
<input type="hidden" name="title" value='$title' >
<input type="hidden" name="pongid" value=$pongid >
<input name="userfile" type="file"  size=60 value="mypic.jpg">
</form>
<script>document.getElementById("pform").submit()</script>
end;

Now that is the Javascript way of posting some file to another server,I guess.
The question is:
Cannot I do this in a PHP manner?
Using fopen for instance?
Do I have to send a special http header?

I'm not sure what you're trying to do here....

Upload a file, using a HTML form, to a server or what?

If that's the case, consider this example:

http://us3.php.net/manual/en/features.file-upload.php

Good Luck §:O)

You need consider the fact that PHP is server side - it cannot upload any files. What it can do is to receive POST data from a form and accept a file posted that way.
Reading the suggested portion of the manual (see dkdude's post) will help.

I (think) I understand that PHP is serverside,
yet that is exactly what I want to do: upload a file,
but not to myself but to another server.

The file resides on my server (where the script also resides) and has to be send to another server, that also runs php. (I have access to that other server too)

Can it be done?

 

[DRJ478]

Yes.

What you would do is make a PHP script that behaves like a browser sending the POST data to the destination.
You have several choices:
a) if you have cURL you can establish a connection to the receiving server using that.
b) PEAR has a HTTP/Request module that allows to send the appropriate headers. Just send the file data along as the data.
c) hand code your socket/stream connection using fsock or stream commands.

Have a look at the HTTP protocol definition to see which headers to send and how to encode data. There are plenty od examples out there.

Cheers.

I see -you want to "POST" a file from your server to another server using PHP, right?

AFAIK that's not supported by PHP (yet). But there should be a way to do it anyway. You're looking for socket functions, I recon.

Have a look here :

http://us3.php.net/sockets

That's some TCP/IP client/server examples. Maybe you could adapt it to fit your needs.

Another ting - are the two servers on the same LAN (and running Windows)? In that case you simply map a folder and let PHP copy the file to the mapped folder (ie. drive) ....

Ok!
I didn't know I had curl, but I do, so I will try this one:

<?php
$file = "file_to_upload.txt";
$submit_url = "[URL unfurl="true"]http://www.url_to_upload_to.com/upload_page.php";[/URL]
$formvars = array("cc"=>"us \n");
$formvars[variable_1] = "something \n";
$formvars[variable_2] = "something else \n";
$formvars[variable_3] = "more \n";
$formvars[upfile] = "@$file"; // "@" causes cURL to send as file and not string (I believe) 
// init curl handle
   $ch = curl_init($submit_url);
curl_setopt($ch, CURLOPT_REFERER, "[URL unfurl="true"]http://www.last_url_for_referer_logs.com");[/URL]  //if server needs to think this post came from elsewhere
curl_setopt($ch, CURLOPT_VERBOSE, 1);
   curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1); // follow redirects recursively
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   curl_setopt($ch, CURLOPT_POSTFIELDS, $formvars);
   // perform post
   echo $pnp_result_page = curl_exec($ch);
curl_close ($ch);
?>
