TEST.PHP

<?php
mysql_connect("127.0.0.1","root","password");
mysql_select_db("addressbook");
$sql = mysql_query("SELECT * FROM colleague");
while($row=mysql_fetch_array($sql))
{
    $output[]=$row;
}
print(json_encode($output));

$fname = $_POST['firstName'];
$telephone = $_POST['telephone'];
$fnam = (String)$fname;
//$lname = (isset($_POST['lastName'])) ? $_POST['lastName'] : null;
//$email = (isset($_POST['email'])) ? $_POST['email'] : null;

mysql_query("INSERT INTO colleague(firstName, lastName, telephone, email)
VALUES ($fnam, 'Smith', $telephone, 'stfu@vib')");

mysql_free_result($sql);
mysql_close();

?>

if i could get rid of the errors in the php output and get fname printed ... it would be great

The output you posted seems to refer to a food.php and doesn't relate to the code you posted?

Edit try this:

$fname = (isset($_POST['firstName'])) ? $_POST['firstName']: null;
$lname = (isset($_POST['lastName'])) ? $_POST['lastName'] : null;

To send data to server you could do this:

private void sendData(ArrayList<NameValuePair> data)
{
     // 1) Connect via HTTP. 2) Encode data. 3) Send data.
    try
    {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new      
        HttpPost("http://www.blah.com/AddAccelerationData.php");
        httppost.setEntity(new UrlEncodedFormEntity(data));
        HttpResponse response = httpclient.execute(httppost);
        Log.i("postData", response.getStatusLine().toString());
            //Could do something better with response.
    }
    catch(Exception e)
    {
        Log.e("log_tag", "Error:  "+e.toString());
    }  
}

then to send lets say:

private void sendAccelerationData(String userIDArg, String dateArg, String timeArg,
        String timeStamp, String accelX, String accelY, String accelZ)
{
    fileName = "AddAccelerationData.php";

    //Add data to be send.
    ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(7);
    nameValuePairs.add(new BasicNameValuePair("userID", userIDArg));
    nameValuePairs.add(new BasicNameValuePair("date",dateArg));
    nameValuePairs.add(new BasicNameValuePair("time",timeArg));
    nameValuePairs.add(new BasicNameValuePair("timeStamp",timeStamp));

    nameValuePairs.add(new BasicNameValuePair("accelX",accelX));
    nameValuePairs.add(new BasicNameValuePair("accelY",accelY));
    nameValuePairs.add(new BasicNameValuePair("accelZ",accelZ));

    this.sendData(nameValuePairs);
}

so then the AddAccelerationData.php file on server is:

<?php
/*
 * What this file does is it:
 * 1) Creates connection to database.
 * 2) Retrieve the data being send.
 * 3) Add the retrieved data to database 'Data'.
 * 4) Close database connection.
 */
require_once '../Connection.php'; //connect to a database/disconnect handler.
require_once '../SendAPI.php'; //deals with sending querys.

$server = new Connection();
$send = new Send();

//Connect to database.
$server->connectDB();

//Retrieve the data.
$userID = $_POST['userID'];
$date = $_POST['date'];
$time = $_POST['time'];

$accelX = $_POST['accelX'];
$accelY = $_POST['accelY'];
$accelZ = $_POST['accelZ'];

//Add data to database 'Data'. //Personal method to query and add to database.
$send->sendAccelerationData($userID, $date, $time, $timeStamp, $accelX, $accelY, $accelZ);


//Disconnect from database.
$server->disconnectDB();
?>
