I know I have seen all similar questions on SO. I tried to solve this error but I failed. I tried almost everything but does not get solution.
My code is as follows:-
public class Tab2 extends Fragment {
private static String TAG = Tab2.class.getSimpleName();
private EditText editText1,editText2,editText3;
private Button button;
private String name,email,password;
private TextInputLayout inputLayoutName, inputLayoutEmail, inputLayoutPassword;

}

public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

This is my php file
<?php
$response = array();
if (isset($_POST['name']) && isset($_POST['email']) && isset ($_POST['password'] ))
{
$name = $_POST['name'];
$email = $_POST['email'];
$password = $_POST['password'];
require_once __DIR__ . '/db_connection.php';
$db = new DB_CONNECT();
$result = mysql_query("Insert into words(name,email,password) values('$name','$email','$password')");
if ($result)
{
$response["success"] = 1;
$response["message"] = "Registration successfully.";
echo json_encode($response);
}
else
{
$response["success"] = 0;
$response["message"] = "Oops! An error occurred.";
echo json_encode($response);
}
}
else
{
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
echo json_encode($response);
}
?>
My JSON response is:-
{"success":0,"message":"Required field(s) is missing"}
Can you identify the error please tell me.
