      and what exactly doesn't work for you? The solution from the topic seems like a legit POST-request to me?

        I have multiple parameters in my php.. for example a post would look like:

        a=upload&t=token&file=image

          if that's all the info you're providing i think nobody will be able to help you.

          What isn't working?
          How you you create the Request?
          etc.

              Just from having a look at the documentation of QNAM::post I can tell that this line can not work.
              @
              networkAM.post(req, url.encodedQuery());
              @

                  Ok. I have no experience with QNAM, but the doc just mentioned QIODevice, const QByteArray & and QHttpMultiPart * as candidates for the second argument of post. And since QUrl inherits from none of these I thought this could not work.

                  I would have tried something like this. But this is just a shot in the dark.
                  @
                  QUrl url ("www.example.com/sth.php");
                  url.addQueryItem("a", "upload");
                  url.addQueryItem("t", token);
                  //url.addQueryItem("file", pictureByteArray.toHex()); Not sure if this is needed with my suggestion

                  QNetworkRequest req;
                  req.setUrl(url);

                  QNetworkAccessManager networkAM;
                  QFile* myImage = new QFile("filePath")
                  if(myImage->open(QIODevice::ReadOnly))
                  {
                  networkAM.post(req, myImage);
                  }
                  @

                    QUrl::encodedQuery() returns a QByteArray

                      Ahh ok. Sry for the confusion I caused.

                      Edit: Maybe the problem is related to this comment from the docs of QNAM::post [quote]data must be open for reading and must remain valid until the finished() signal is emitted for this reply.[/quote]

                      The object returned by QUrl::encodedQuery goes out of scope after the function returns ?

                        That is not the problem.. I created a new QByteArray to store the return value but still nothing happens... I think I must create my own model for sending after sniffing what a post method in php sends to the server :( bleah got into software to escape web dev and now i have to do this... Thank you I will submit some code example after I finish (if I finish)

                          ^^ Completely agree on the web dev part. Maybe "the example in the QHtmlMultiPart doc":http://qt-project.org/doc/qt-4.8/qhttpmultipart.html#details can be helpful ? Anyways good luck.

                            Try to use "FormPost":http://www.tuckdesign.com/sources/Qt

                            I have a similar problem when I am starting to code for an API which includes a "HTML Form" for sending files to a server. I used QNAM::post()... tried QHttpMultiPart... but still they won't work. Found out that there is something wrong with QHttpMultiPart and it uses a different specification (RFC 2046).

                            FormPost should work. I just modified some parts of it and it worked like a charm. You can visit my "site":https://github.com/Code-ReaQtor/libqsendspace/tree/master/qsendspace/src for reference.

                            Please visit my open-source projects at https://github.com/Code-ReaQtor.

                                Ok so QHttpMultiPart doesn't work (wish I would've checked the post sooner, before head banging my head with it, seeing as someone already tried using this). Will try your solution tomorrow, thank you Code_ReaQtor
