Sending data to php page with java
<p>I am trying to send the POST data from java to a PHP page. However it is not working. Whatever I echo in the php page works fine but when I send data it gives- 'undefined index'
What could be the problem ?
This is my java file.</p>

<pre><code>import java.net.*;
import java.io.*;

class Main {
public static void main(String args[]) throws IOException {

    URL url = new URL("http://localhost/CD/user/test");
    String result = "";
    String data = "fName=" + URLEncoder.encode("Atli", "UTF-8");
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    try {

        connection.setDoInput(true);
        connection.setDoOutput(true);
        connection.setUseCaches(false);
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Content-Type",
                "application/x-www-form-urlencoded");

        // Send the POST data
        DataOutputStream dataOut = new DataOutputStream(
                connection.getOutputStream());
        dataOut.writeBytes(data);
        dataOut.flush();
        dataOut.close();

        BufferedReader in = new BufferedReader(new InputStreamReader(
                url.openStream()));

        String g;
        while ((g = in.readLine()) != null) {
            result += g;
        }
        in.close();

    } finally {
        connection.disconnect();
        System.out.println(result);
    }

}
}
</code></pre>

<p>And here is my php controller:</p>

<pre><code>public function test(){

    $test=$_POST['fName'];
    $all="This is a ";
    $all=$all." ".$test;
    echo $all;



}  
</code></pre>

<p>When I just send a url request , I get the ouput as 'This is a'. So it is connecting to the url and everything but while sending data, it is not working. Please help! Thank you.</p>
