Sistem Login Unity Dengan PHP dan MySQL
Dalam tutorial ini, saya akan menunjukkan cara membuat sistem login di Unity menggunakan PHP dan MySQL.
Tutorial ini membutuhkan server dengan cPanel bersama dengan PHP dan MySQLi (versi perbaikan dari MySQL).
Jangan ragu untuk memeriksa hosting premium VPS yang terjangkau atau alternatif Shared Hosting yang lebih murah.
Langkah 1: Siapkan Basis Data MySQL
- Masuk ke cPanel
- Klik Database MySQL di bagian DATABASES
- Di bawah bagian "Create New Database" ketik nama database Anda lalu klik "Create Database"
Setelah database dibuat, kita perlu membuat pengguna yang akan dikaitkan dengannya:
- Ketik Nama Pengguna di bawah bagian "MySQL Users" lalu ketikkan kata sandi (atau sebaiknya gunakan Pembuat Kata Sandi untuk menghasilkan kata sandi yang kuat). Jangan lupa untuk menyimpan kata sandi di suatu tempat, itu akan diperlukan nanti.
Terakhir, kita perlu menugaskan pengguna ke database dengan serangkaian izin tertentu.
- Di bawah bagian "Add User To Database" pilih pengguna dan database yang baru dibuat lalu klik "Add"
Setelah mengklik "Add" Anda akan disajikan daftar Hak Istimewa. Hanya pilih hak istimewa yang Anda rencanakan untuk digunakan di masa mendatang. Yang paling umum adalah DELETE, SELECT, INSERT, dan UPDATE:
- Klik "Make Changes" untuk menyelesaikan
Langkah 2: Buat Tabel MySQL
Tabel MySQL akan menyimpan nilai-nilai yang diberikan oleh pengguna, seperti nama pengguna, email, kata sandi, dll.
- Klik "phpMyAdmin" di bawah bagian DATABASES
- Klik pada database yang baru dibuat lalu klik pada tab SQL
- Tempelkan kode di bawah ini ke editor kueri lalu klik "Go"
SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO";
SET AUTOCOMMIT = 0;
START TRANSACTION;
SET time_zone = "+00:00";
--
-- Table structure for table `sc_users`
--
CREATE TABLE `sc_users` (
`user_id` int(11) NOT NULL,
`username` varchar(20) CHARACTER SET utf8 NOT NULL,
`email` varchar(254) CHARACTER SET utf8 NOT NULL,
`password` char(60) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`registration_date` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
--
-- Indexes for table `sc_users`
--
ALTER TABLE `sc_users`
ADD PRIMARY KEY (`user_id`),
ADD UNIQUE KEY `username` (`username`),
ADD UNIQUE KEY `email` (`email`);
--
-- AUTO_INCREMENT for table `sc_users`
--
ALTER TABLE `sc_users`
MODIFY `user_id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=1;
COMMIT;Query di atas akan membuat tabel baru 'sc_users' yang akan menyimpan data pengguna.
Langkah 3: Logika Sisi Server Program
Logika sisi server akan terdiri dari skrip PHP yang akan menerima dan memproses data Posting dari Unity.
File pertama adalah database.php yang akan terhubung ke database MySQL menggunakan ekstensi PHP MySQLi.
database.php
<?php
$host = "localhost"; // Host name
$db_username = "DATABASE_USER"; // Mysql username
$db_password = "USER_PASSWORD"; // Mysql password
$db_name = "DATABASE_NAME"; // Database name
$mysqli_conection = mysqli_connect($host, $db_username, $db_password, $db_name)or die("cannot connect");
?>Ganti DATABASE_USER, USER_PASSWORD, dan DATABASE_NAME dengan nilai Anda.
File kedua adalah register.php. File ini akan menerima data posting dari Unity dan memasukkan catatan pengguna baru ke dalam tabel database.
daftar.php
<?php
if(isset($_POST["email"]) && isset($_POST["username"]) && isset($_POST["password1"]) && isset($_POST["password2"])){
$errors = array();
$emailMaxLength = 254;
$usernameMaxLength = 20;
$usernameMinLength = 3;
$passwordMaxLength = 19;
$passwordMinLength = 5;
$email = strtolower($_POST["email"]);
$username = $_POST["username"];
$password1 = $_POST["password1"];
$password2 = $_POST["password2"];
//Validate email
if(preg_match('/\s/', $email)){
$errors[] = "Email can't have spaces";
}else{
if(!validate_email_address($email)){
$errors[] = "Invalid email";
}else{
if(strlen($email) > $emailMaxLength){
$errors[] = "Email is too long, must be equal or under " . strval($emailMaxLength) . " characters";
}
}
}
//Validate username
if(strlen($username) > $usernameMaxLength || strlen($username) < $usernameMinLength){
$errors[] = "Incorrect username length, must be between " . strval($usernameMinLength) . " and " . strval($usernameMaxLength) . " characters";
}else{
if(!ctype_alnum ($username)){
$errors[] = "Username must be alphanumeric";
}
}
//Validate password
if($password1 != $password2){
$errors[] = "Passwords do not match";
}else{
if(preg_match('/\s/', $password1)){
$errors[] = "Password can't have spaces";
}else{
if(strlen($password1) > $passwordMaxLength || strlen($password1) < $passwordMinLength){
$errors[] = "Incorrect password length, must be between " . strval($passwordMinLength) . " and " . strval($passwordMaxLength) . " characters";
}else{
if(!preg_match('/[A-Za-z]/', $password1) || !preg_match('/[0-9]/', $password1)){
$errors[] = "Password must contain atleast 1 letter and 1 number";
}
}
}
}
//Check if there is user already registered with the same email or username
if(count($errors) == 0){
//Connect to database
require dirname(__FILE__) . '/database.php';
if ($stmt = $mysqli_conection->prepare("SELECT username, email FROM sc_users WHERE email = ? OR username = ? LIMIT 1")) {
/* bind parameters for markers */
$stmt->bind_param('ss', $email, $username);
/* execute query */
if($stmt->execute()){
/* store result */
$stmt->store_result();
if($stmt->num_rows > 0){
/* bind result variables */
$stmt->bind_result($username_tmp, $email_tmp);
/* fetch value */
$stmt->fetch();
if($email_tmp == $email){
$errors[] = "User with this email already exist.";
}
else if($username_tmp == $username){
$errors[] = "User with this name already exist.";
}
}
/* close statement */
$stmt->close();
}else{
$errors[] = "Something went wrong, please try again.";
}
}else{
$errors[] = "Something went wrong, please try again.";
}
}
//Finalize registration
if(count($errors) == 0){
$hashedPassword = password_hash($password1, PASSWORD_BCRYPT);
if ($stmt = $mysqli_conection->prepare("INSERT INTO sc_users (username, email, password) VALUES(?, ?, ?)")) {
/* bind parameters for markers */
$stmt->bind_param('sss', $username, $email, $hashedPassword);
/* execute query */
if($stmt->execute()){
/* close statement */
$stmt->close();
}else{
$errors[] = "Something went wrong, please try again.";
}
}else{
$errors[] = "Something went wrong, please try again.";
}
}
if(count($errors) > 0){
echo $errors[0];
}else{
echo "Success";
}
}else{
echo "Missing data";
}
function validate_email_address($email) {
return preg_match('/^([a-z0-9!#$%&\'*+-\/=?^_`{|}~.]+@[a-z0-9.-]+\.[a-z0-9]+)$/i', $email);
}
?>Dan file terakhir adalah login.php yang akan menerima kredensial dan memeriksanya dengan tabel sc_users.
login.php
<?php
if(isset($_POST["email"]) && isset($_POST["password"])){
$errors = array();
$email = $_POST["email"];
$password = $_POST["password"];
//Connect to database
require dirname(__FILE__) . '/database.php';
if ($stmt = $mysqli_conection->prepare("SELECT username, email, password FROM sc_users WHERE email = ? LIMIT 1")) {
/* bind parameters for markers */
$stmt->bind_param('s', $email);
/* execute query */
if($stmt->execute()){
/* store result */
$stmt->store_result();
if($stmt->num_rows > 0){
/* bind result variables */
$stmt->bind_result($username_tmp, $email_tmp, $password_hash);
/* fetch value */
$stmt->fetch();
if(password_verify ($password, $password_hash)){
echo "Success" . "|" . $username_tmp . "|" . $email_tmp;
return;
}else{
$errors[] = "Wrong email or password.";
}
}else{
$errors[] = "Wrong email or password.";
}
/* close statement */
$stmt->close();
}else{
$errors[] = "Something went wrong, please try again.";
}
}else{
$errors[] = "Something went wrong, please try again.";
}
if(count($errors) > 0){
echo $errors[0];
}
}else{
echo "Missing data";
}
?>- Unggah ketiga file tersebut ke folder public_html Anda.
Langkah 4: Program Logika Klien Unity
Logika klien akan terdiri dari skrip C# yang akan memposting data ke skrip PHP.
- Buat skrip baru di Unity dan beri nama SC_LoginSystem lalu tempel kode di bawah ini di dalamnya:
SC_LoginSystem.cs
using System.Collections;
using UnityEngine;
using UnityEngine.Networking;
public class SC_LoginSystem : MonoBehaviour
{
public enum CurrentWindow { Login, Register }
public CurrentWindow currentWindow = CurrentWindow.Login;
string loginEmail = "";
string loginPassword = "";
string registerEmail = "";
string registerPassword1 = "";
string registerPassword2 = "";
string registerUsername = "";
string errorMessage = "";
bool isWorking = false;
bool registrationCompleted = false;
bool isLoggedIn = false;
//Logged-in user data
string userName = "";
string userEmail = "";
string rootURL = "http://YOUR_SITE.COM/"; //Path where php files are located
void OnGUI()
{
if (!isLoggedIn)
{
if (currentWindow == CurrentWindow.Login)
{
GUI.Window(0, new Rect(Screen.width / 2 - 125, Screen.height / 2 - 115, 250, 230), LoginWindow, "Login");
}
if (currentWindow == CurrentWindow.Register)
{
GUI.Window(0, new Rect(Screen.width / 2 - 125, Screen.height / 2 - 165, 250, 330), RegisterWindow, "Register");
}
}
GUI.Label(new Rect(5, 5, 500, 25), "Status: " + (isLoggedIn ? "Logged-in Username: " + userName + " Email: " + userEmail : "Logged-out"));
if (isLoggedIn)
{
if (GUI.Button(new Rect(5, 30, 100, 25), "Log Out"))
{
isLoggedIn = false;
userName = "";
userEmail = "";
currentWindow = CurrentWindow.Login;
}
}
}
void LoginWindow(int index)
{
if (isWorking)
{
GUI.enabled = false;
}
if (errorMessage != "")
{
GUI.color = Color.red;
GUILayout.Label(errorMessage);
}
if (registrationCompleted)
{
GUI.color = Color.green;
GUILayout.Label("Registration Completed!");
}
GUI.color = Color.white;
GUILayout.Label("Email:");
loginEmail = GUILayout.TextField(loginEmail);
GUILayout.Label("Password:");
loginPassword = GUILayout.PasswordField(loginPassword, '*');
GUILayout.Space(5);
if (GUILayout.Button("Submit", GUILayout.Width(85)))
{
StartCoroutine(LoginEnumerator());
}
GUILayout.FlexibleSpace();
GUILayout.Label("Do not have account?");
if (GUILayout.Button("Register", GUILayout.Width(125)))
{
ResetValues();
currentWindow = CurrentWindow.Register;
}
}
void RegisterWindow(int index)
{
if (isWorking)
{
GUI.enabled = false;
}
if (errorMessage != "")
{
GUI.color = Color.red;
GUILayout.Label(errorMessage);
}
GUI.color = Color.white;
GUILayout.Label("Email:");
registerEmail = GUILayout.TextField(registerEmail, 254);
GUILayout.Label("Username:");
registerUsername = GUILayout.TextField(registerUsername, 20);
GUILayout.Label("Password:");
registerPassword1 = GUILayout.PasswordField(registerPassword1, '*', 19);
GUILayout.Label("Password Again:");
registerPassword2 = GUILayout.PasswordField(registerPassword2, '*', 19);
GUILayout.Space(5);
if (GUILayout.Button("Submit", GUILayout.Width(85)))
{
StartCoroutine(RegisterEnumerator());
}
GUILayout.FlexibleSpace();
GUILayout.Label("Already have an account?");
if (GUILayout.Button("Login", GUILayout.Width(125)))
{
ResetValues();
currentWindow = CurrentWindow.Login;
}
}
IEnumerator RegisterEnumerator()
{
isWorking = true;
registrationCompleted = false;
errorMessage = "";
WWWForm form = new WWWForm();
form.AddField("email", registerEmail);
form.AddField("username", registerUsername);
form.AddField("password1", registerPassword1);
form.AddField("password2", registerPassword2);
using (UnityWebRequest www = UnityWebRequest.Post(rootURL + "register.php", form))
{
yield return www.SendWebRequest();
if (www.result != UnityWebRequest.Result.Success)
{
errorMessage = www.error;
}
else
{
string responseText = www.downloadHandler.text;
if (responseText.StartsWith("Success"))
{
ResetValues();
registrationCompleted = true;
currentWindow = CurrentWindow.Login;
}
else
{
errorMessage = responseText;
}
}
}
isWorking = false;
}
IEnumerator LoginEnumerator()
{
isWorking = true;
registrationCompleted = false;
errorMessage = "";
WWWForm form = new WWWForm();
form.AddField("email", loginEmail);
form.AddField("password", loginPassword);
using (UnityWebRequest www = UnityWebRequest.Post(rootURL + "login.php", form))
{
yield return www.SendWebRequest();
if (www.result != UnityWebRequest.Result.Success)
{
errorMessage = www.error;
}
else
{
string responseText = www.downloadHandler.text;
if (responseText.StartsWith("Success"))
{
string[] dataChunks = responseText.Split('|');
userName = dataChunks[1];
userEmail = dataChunks[2];
isLoggedIn = true;
ResetValues();
}
else
{
errorMessage = responseText;
}
}
}
isWorking = false;
}
void ResetValues()
{
errorMessage = "";
loginEmail = "";
loginPassword = "";
registerEmail = "";
registerPassword1 = "";
registerPassword2 = "";
registerUsername = "";
}
}Ganti http://YOUR_SITE.COM/ dengan nilai Anda (Ini harus berupa jalur root tempat Anda mengunggah file PHP). Selain itu, pastikan untuk menggunakan HTTPS jika server Anda memasang Sertifikat SSL.
- Buat GameObject baru dan beri nama "LoginSystem"
- Lampirkan ke SC_LoginSystem ke Objek LoginSystem
Tekan Mainkan lalu klik Daftar untuk membuat akun baru atau memberikan kredensial untuk login.
