CURL - postfields how to replicate these headers

[futureawesome]

-----------------------------30870195987994
Content-Disposition: form-data; name="file[]"; filename=""
Content-Type: application/octet-stream


-----------------------------30870195987994
Content-Disposition: form-data; name="file[]"; filename="K43TA206.zip"
Content-Type: application/zip

So I'm trying to write a basic curl upload script for bitshare. I know there is a rapidleech plugin for it, but I'm just wondering how do I pass the empty file as a post field. Bitshare is weird in that they post an empty file array in their header. If I leave it out, the upload does not work.

In the rapidleech plugin, they open a socket and literally just paste that exact section. For curl I pass in an array format usually.

array ( "file[]" => "@$filename");

I've tried

array ( "file[]" => "", "file[]" => "@$filename" ) 

But it doesn't work. Any help would be appreciated.

try

"file[]=&file[]={@$filename}"

try

"file[]=&file[]={@$filename}" 

That one should be working. Have you tried it?

[mRAza]

you have to send 2 variables in your post array, one with filename and other with location, here is example for bitshare.

              $postData = array(
                    'APC_UPLOAD_PROGRESS' => $progress_key,
                    'APC_UPLOAD_USERGROUP' => $usergroup_key,
                    'UPLOAD_IDENTIFIER' => $progress_key,
                    'file[]"; filename="' => basename($filelocation),
                    'file[]' => $filelocation
                    );

try

"file[]=&file[]={@$filename}" 

Do I append this to the postdata array?

                    'file[]' => $filelocation
                    ); 

What happens to the usual @ infront of the file?

Thanks for your suggestions!

EDIT: I've tried what mRaza suggested and this is the headers returned from CURL.

HTTP/1.1 100 Continue HTTP/1.1 200 OK Server: nginx/0.8.50 Date: Wed, 24 Aug 2011 02:38:25 GMT Content-Type: text/html Transfer-Encoding: chunked Connection: close X-Powered-By: PHP/5.3.0 no files

don't append it, put it the place of the post array

[futureawesome]

Oh so in the form of a GET?

So when i post with just

$post = "file[]=&file[]={@$x}"; 

The header returned is:

HTTP/1.1 200 OK Server: nginx/0.8.50 
Date: Wed, 24 Aug 2011 03:34:12 GMT 
Content-Type: text/html 
Transfer-Encoding: chunked 
Connection: close 
X-Powered-By: PHP/5.3.0  

wrong parameter count

So when I post with the required fields:

$post = "APC_UPLOAD_PROGRESS={$progress_key}&APC_UPLOAD_USERGROUP={$usergroup_key}&UPLOAD_IDENTIFIER={$progress_key}&file[]=&file[]={@$x}"; 

The header returned is:

HTTP/1.1 200 OK
Server: nginx/0.8.50
Date: Wed, 24 Aug 2011 03:38:07 GMT
Content-Type: text/html

you have to add @ in file location:

              $postData = array(
                    'APC_UPLOAD_PROGRESS' => $progress_key,
                    'APC_UPLOAD_USERGROUP' => $usergroup_key,
                    'UPLOAD_IDENTIFIER' => $progress_key,
                    'file[]"; filename="' => basename($filelocation),
                    'file[]' => "@$filelocation"
                    );
