Hi .
test code is ```
QUrl testUrl("http://app/test.php");
QNetworkAccessManager* mgr = new QNetworkAccessManager();
QNetworkRequest request(testUrl);
QHttpMultiPart *multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);

QHttpPart textPart;
 textPart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"text\""));
 textPart.setBody("my text");

QHttpPart imagePart;
imagePart.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("image/jpeg"));
imagePart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"image\""));
request.setRawHeader("Content-ID", "my@content.id");
//request.setRawHeader("User-Agent", "Mozilla/5.21");
QFile *file = new QFile("C:/xampp/app/images/uploads/product/1024_blue_earth_wallpaper.jpg");
qDebug() << file->open(QIODevice::ReadOnly);
imagePart.setBodyDevice(file);
file->setParent(multiPart);
multiPart->append(textPart);
multiPart->append(imagePart);

 QNetworkReply *reply = mgr->post(request,multiPart);

php code is 

<?php
$x="";
foreach (getallheaders() as $name => $value) {
$x.="$name: $value\n";
}

$json_string = json_encode($_FILES)." boş geçme 111 ".$x.$_POST['text'].$_FILERS['image']['tmp_name'];

$file_handle = fopen('my_filename.json', 'w');
fwrite($file_handle, $json_string);
fclose($file_handle);
//echo "[{}]";


 //$sonuc = array('sonuc' =>'olumlu' );
 //$sonucValue = array_values($sonuc);
 //echo json_encode($sonucValue);
 $myArr = array( "name"=>"John", "title" => "student");

$myJSON = json_encode($myArr);

//echo $myJSON;
//echo "tamamdir";

//$files = multiple($_FILES);
//echo json_encode($_FILES);
//print_r($_FILES);

?>

and result

Hi SGaist .there is no connection error . everything is ok.

The following code works

QUrl testUrl("http://app/test.php");
    QNetworkAccessManager* mgr = new QNetworkAccessManager();
    QNetworkRequest request(testUrl);
    QHttpMultiPart *multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);

    QHttpPart textPart;
     textPart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"text\""));
     textPart.setBody("Merhaba ");

     QStringList headers;
     headers

hi guys .this code is working on localhost . but not on web http addr
how can i figure out this problem .

QUrl testUrl("http://localhost/test.php");
    QNetworkAccessManager* mgr = new QNetworkAccessManager();
    QNetworkRequest request(testUrl);
    QHttpMultiPart *multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);

    QHttpPart textPart;
     textPart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"text\""));
     textPart.setBody("my text");


    request.setRawHeader("Content-ID", "my@content.id");
    //request.setRawHeader("User-Agent", "Mozilla/5.21");
    QFile *file = new QFile("C:/xampp/app/images/uploads/product/1024_blue_earth_wallpaper.jpg");
    qDebug() << file->open(QIODevice::ReadOnly);
    //qDebug() << file->;
    QFileInfo fileInfo("C:/xampp/app/images/uploads/product/1024_blue_earth_wallpaper.jpg");
    QHttpPart imagePart;
    imagePart.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("image/jpeg"));
    imagePart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant(QString("form-data; name=\"image\";filename=\"%1\"").arg(fileInfo.fileName()).toLatin1()) );
    imagePart.setBodyDevice(file);
    file->setParent(multiPart);
    multiPart->append(textPart);
    multiPart->append(imagePart);

     QNetworkReply *reply = mgr->post(request,multiPart);

Hi,

You seem to not connect any error related signals. You should add them in order to understand what is happening.

I didn't wrote about connection error, but about connecting the error signal of QNetworkReply to know when something goes wrong.
