мое приложение, которое должно передавать пользовательские входные данные в мою базу данных SQL. Я должен заполнить все поля, а затем нажмите "Сохранить", чтобы данные обновлялись в моем sql файле. После очистки много ошибок, я, наконец, застрял на 1 ошибка, которую я не могу решить. любая предоставленная помощь будет чрезвычайно оценена. Пожалуйста, совет, какие изменения я могу сделать, чтобы избавиться от ошибки. Ошибка

      <?php

if (isset($_POST['driver'], $_POST['licencenum'], $_POST['officer'], $_POST['speed'] , $_POST['fine'],$_POST['category'])){

$licencenum = $_POST['licencenum'];
$officer = $_POST['officer'];
$speed = $_POST['speed'];
$fine = $_POST['fine'];
$category = $_POST['category'];


// include db connect class
require_once __DIR__ . '/db_connect.php';

// connecting to db
$db = new DB_CONNECT();

// mysql inserting a new row
$result = mysql_query("INSERT INTO fineregister(driver,licencenum,officer,speed,fine,category) VALUES                ('$driver','$licencenum','$officer','$speed','$fine',      '$category')");

// check if row inserted or not
if ($result) {
    // successfully inserted into database
    $response["success"] = 1;
    $response["message"] = "Speed Ticket Successfully Registered.";

    // echoing JSON response
    echo json_encode($response);
} else {
    // failed to insert row
    $response["success"] = 0;
    $response["message"] = "Oops! An error occurred.";

    // echoing JSON response
    echo json_encode($response);
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";

// echoing JSON response
echo json_encode($response);
}
?>

Ответ 1

HttpResponse response = client.execute(httpPost);
String responseBody = EntityUtils.toString(response.getEntity());

pass the string into json array and get the response value

            JSONArray jsArray = new JSONArray(responseBody);
            JSONObject js = jsArray.getJSONObject(0);
            String returnvalmsg = js.getString("message");
            String returnvalsucc = js.getString("success");
