    @Vineela You should start here: http://doc.qt.io/qt-5/qnetworkaccessmanager.html
    For JSON: http://doc.qt.io/qt-5/qjsondocument.html

          @Vineela said in How to get data from URL/.php file and display in my fields:

          array strings

          What do you mean by this? Please explain better what you want to achieve.
          To display a string you can use QLabel.
          To add an entry to QComboBox use http://doc.qt.io/qt-5/qcombobox.html#addItem

                  @Vineela If the server sends Json then you have to deal with Json. I gave you a link to documentation for accessing Json data using Qt, you wrote you didn't read it. Now it is time to read that documentation.

                      @Vineela Did you read the documentation?

                      AByteArray data = "YOUR JSON DATA";
                      QJsonDocument doc = QJsonDocument::fromJson(data);
                      QJsonArray array = doc.array();
                      QJsonObject object = array.at(0).toObject();
                      QString code = object["LeaderCode"].toString();
                      

                      To add to QComboBox please refer to the documentation: http://doc.qt.io/qt-5/qcombobox.html#insertItem

                          @Vineela First, you need to make sure you parsed Json correctly. The code I posted does not do that!
                          Then please show your current code (reading Json and putting entries into combo box).
                          One more question: are you sure you actually got the reply from server with Json?

                              @Vineela Your Json string is invalid as it contains <pre></pre>. You need to remove these HTML tags first.

                              data = data.replace("<pre>", "").replace("</pre>", "");
                              QJsonDocument doc = QJsonDocument::fromJson(data);
                              QJsonArray array = doc.array();

                                  @Vineela Come on! If you get GNL0001 via array.at(0) then you get GNL0002 via array.at(1)...

                                        @jsulm well I've added this
                                        for(int i=0 ;i<array.size();i++){
                                        QJsonObject object = array.at(i).toObject();
                                        } it worked
