post thru fsockopen

Hi there

Im tring to send a file with a php script, Im using php 5.2 on a Win
2003 server. At the other end I just save the file and process the data
and print the result, then fetch the output and write a report. But this
doesn't work, any one got an idea? The file never get to the other end?
When I do a var_export($_POST) is empty.


This is the code I use:
function postFile($file,$host,$path)
{
$remote_page =3D "http://".$host.$path;
$boundary =3D
"---------------------------".substr(md5(rand(0,32000)),0,10 );

// read the file
$fp =3D @fopen($file,"r");
if (!$fp) die ("Cannot read $file !!");
$content_file =3D fread($fp,filesize($file));
fclose($fp);

// define HTTP POST DATA
$data =3D "--$boundary\n".
"Content-Disposition: form-data; name=3D\"file\"; =
filename=3D\"$file\"\n".
"Content-Type: application/octet-stream\n\n$content_file".
"--$boundary--\r\n\r\n";

$msg =3D "POST $remote_page HTTP/1.0\n".
"Content-Type: multipart/form-data; boundary=3D$boundary\n".
"Content-Length: ".strlen($data)."\r\n\r\n";

// Open socket connection ...
$f =3D fsockopen($host,80, $errno, $errstr, 30);
if ($f)
{

// Send the data
fputs($f,$msg.$data);

// retrieve the response
$result=3D"";

while (!feof($f)) {
$result.=3Dfread($f,1024);
}

fclose($f);
// write the response (if needed)
return $result;
} else {
die ("Cannot connect !!!");
}
}

If you can use file_get_contents() with the allow_url_fopen =3D yes directi=
ve in=20
php.ini it would be easier.
=46rom http://us2.php.net/manual/en/wrappers.http.php :

$postdata =3D http_build_query(
array(
'var1' =3D> 'some content',
'var2' =3D> 'doh'
)
);

$opts =3D array('http' =3D>
array(
'method' =3D> 'POST',
'header' =3D> 'Content-type: application/x-www-form-urlencoded',
'content' =3D> $postdata
)
);

$context =3D stream_context_create($opts);

$result =3D file_get_contents('http://example.com/submit.php', false, $cont=
ext);

?>

I have done something similar except I used the $_REQUEST variable in the=20
remote script rather than doing a POST. I had just a small amount of data t=
o=20
pass so $_REQUEST worked for me.

On Windows with PHP4 I had to do some tricks to get this type of thing to=20
work. On Linux with PHP5 it worked flawlessly.

Thanks,
James

Couldn't that be because you should be checking $_FILES instead of $_POST?

Anyway, I use this HTTP client class and it supports file uploading easily.

Thanks for the example. But I found the error in my script,=20
"Content-Disposition: form-data; name=3D\"file\"; =
filename=3D\"$file\"\n".

I had to do a basename($file) first of course :)
