PHP script to connect MYSQL database to Android DevicePHP Error - php

Question

I am having a problem with the connection to my PHP script, it keeps on returning "Oops! Its this one." - which is my error message if it could not inset into the mySQL database.
///PHP SCRIPT
<?php
$con = mysqli_connect("postgrad.nmmu.ac.za", "Christian", "Christian123", "drmdb");
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
// array for JSON response
$response = array();
$PointerID = $_POST['PointerID'];
$ActivityID = $_POST['ActivityID'];
$StartX = $_POST['StartX'];
$EndX = $_POST['EndX'];
$StartY = $_POST['StartY'];
$EndY = $_POST['EndY'];
$Content = $_POST['Content'];
$Head = $_POST['Head'];
$NodeID = $_POST['NodeID'];
$Step = $_POST['Step'];
$result = mysqli_query(
$con,
"INSERT INTO pointersequence(PointerID, ActivityID, StartX, StartY, EndX, EndY, Content, Head, NodeID, Step) VALUES('$PointerID','$ActivityID', '$StartX', '$StartY', '$EndX', '$Content', '$Head', '$NodeID', '$Step')"
);
// check if row inserted or not
if ($result) {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "Person successfully created hahaha.";
// echoing JSON response
echo json_encode($response);
} else {
// failed to insert row
$response["success"] = 0;
$response["message"] = "Oops! Its this one.";
// echoing JSON response
echo json_encode($response);
}
mysql_close($con);
?>
OUTPUT: Oops! Its this one.
