Upload picture with Qt

anzarQt

hello,
I want to upload a picture with Qt and send it to a script php that exist in server
i try this example but it doesn-t work:
@
void upload::uploadImage()
{

//path image
QString path("C:/QtProjets/uploadImage/test.png");
//php script that receives the image
QNetworkRequest requete(QUrl("http://link server/upload.php")); //our server with php-script

QByteArray boundary = "-------------------------87142694621188";
QFile file&#40;path&#41;;
if (!file.open(QIODevice::ReadOnly))
{
    qDebug()<<"erreur read image";
    return;
}
QByteArray fileContent(file.readAll());

QByteArray data = "--" + boundary + "\r\n";
data += "Content-Disposition: form-data; name=\"data\"; filename=\"test.png\";\r\n";
//add picture to data
data += "Content-Type: image/png\r\n\r\n" + fileContent + "\r\n";
data += "--" + boundary + "--\r\n";

requete.setRawHeader("Content-Type", "multipart/form-data; boundary=" + boundary);
requete.setRawHeader("Content-Length", QString::number(data.size()).toAscii());
file.close();
qDebug() <<"data"<< data.size();
QNetworkAccessManager *am = new QNetworkAccessManager(this);
QNetworkReply *reply = am->post(requete,"data="+data);

QObject::connect(am, SIGNAL(finished(QNetworkReply*)), this, SLOT(replyFinished(QNetworkReply*)));

}
/************************************ response /
/***********************************************************************/

void upload::replyFinished(QNetworkReply *reply)
{
reply->open(QIODevice::ReadOnly);

// if the response is correct
if(reply-&gt;error() == QNetworkReply::NoError)
{
    QByteArray str=(reply-&gt;readAll());
    QString response = QString::fromUtf8(str.data(), str.size());
    qDebug()&lt;&lt;" re "<<response;
}

//error sever

else
    qDebug()<<"error response server";

}
@

and my code php ( upload.php):
@<?php

$data =$_POST['data'];
$fp = fopen("image.png", 'w+');
fputs($fp, $data);
fclose($fp);
echo 'hello'

?>

@
i think the problem is in this lines 21 ans 22:
@
data += "Content-Type: image/jpeg\r\n\r\n" + fileContent + "\r\n";
data += "--" + boundary + "--\r\n";@
Any help and advice would be much appreciated!

This line:
@data += "Content-Disposition: form-data; name="data"; filename="test.png";\r\n";@

should be:

@data += "Content-Disposition: form-data; name="pic"; filename="test.png";\r\n";@
