How to get data from URL/.php file and display in my fields

[jsulm]

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

[Vineela]

@jsulm Thank you I'll try now

[Vineela]

Thanks @jsulm it worked I've gone through the first link but not tried with the json one but i got what i wanted.

[Vineela]

@Vineela @jsulm i have one more request that how can I display 2 array strings from URL/.php and add to comboBox ??

[jsulm]

@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]

@jsulm From my .php link I'll get 2 or more arrays so how do i get them and add it to my combo box.

[jsulm]

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

2 or more arrays

Are you talking about Json?

[Vineela]

@jsulm yep, I thought I may not use JSON, do I have to use JSON if yes then help me with JSON.

[jsulm]

@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]

@jsulm this is the output of my link , well from this i need to get those "GNL0001 & GNL002" and add them to my combo box ,so i hope you get what I'm saying please help me out with this.
[
{
"LeaderCode": "GNL0001"
},
{
"LeaderCode": "GNL0002"
}
]

[jsulm]

@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]

@jsulm well yes i've done and read the documentation but small thing is item which i added is blank.

[jsulm]

@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]

@jsulm

void MainWindow::datainDaHouse2(QByteArray data)
{
//first
 qDebug()<< "Jason value" +data;
 QJsonDocument doc = QJsonDocument::fromJson(data);
    QJsonArray array = doc.array();
    QJsonObject object = array.at(0).toObject();
    QString code = object["LeaderCode"].toString();

        ui->comboBox_54->insertItem(3,code);
     //second
        qDebug()<< "InsertCode" +code;
}

well this is my current code and my output for qDebug is,
//first
"Jason value<pre>[\n {\n "LeaderCode": "GNL0001"\n },\n {\n "LeaderCode": "GNL0002"\n }\n]</pre>"
//second here where my output getting blank
"InsertCode"

[jsulm]

@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();
QJsonObject object = array.at(0).toObject();
QString code = object["LeaderCode"].toString();

ui->comboBox_54->insertItem(3,code);
//second
qDebug()<< "InsertCode" +code;

[Vineela]

@jsulm yes i got this "InsertCodeGNL0001" but wat abt GNL0002??

[jsulm]

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

[Vineela]

@jsulm i know but can't i add it within this line
QJsonObject object = array.at(0).toObject(); so i have to write another object2

[jsulm]

@Vineela

object = array.at(1).toObject();
QString code = object["LeaderCode"].toString();
ui->comboBox_54->insertItem(3,code);
//second
qDebug()<< "InsertCode" +code;

[Vineela]

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