Call of duty 2 reg and login system mysql.

[Mofli]

Hello. Does anyone have a way that is based on mysql and has registration - login? There are many cheaters on my server, so I would like help. Thanks to anyone who can help. I can't find any of these on the forum.

in this system, there is only entry when joining. Registration is only on the website and I made it so that only I as admin can register the members. I created the Admin panel based on php.

php file:

<?php
$servername = "localhost";
$username = "";
$password = ""; 
$dbname = ""; 
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("Kapcsolódási hiba: " . $conn->connect_error);
}
$player_username = $_POST['username'];
$player_password = $_POST['password'];
$sql = "SELECT * FROM users WHERE username = ?";
$stmt = $conn->prepare($sql);
$stmt->bind_param("s", $player_username);
$stmt->execute();
$result = $stmt->get_result();
if ($result->num_rows > 0) {
    $user = $result->fetch_assoc();
    if (password_verify($player_password, $user['password'])) {
        echo "success";  
    } else {
        echo "invalid_password"; 
    }
} else {
    echo "no_user";  
}
$conn->close();
?>

login script:

login(player) {
    player iprintlnbold("Add meg a felhasználónevet:");
    player waitTill("say", username);

    player iprintlnbold("Add meg a jelszót:");
    player waitTill("say", password);

    request = "curl -X POST -d 'username=" + username + "&password=" + password + "' http://site.com/file.php";
    
    response = waitexec(request);
    
    if (response == "success") {
        player iprintlnbold("Bejelentkezés sikeres!");
    } else if (response == "invalid_password") {
        player iprintlnbold("Hibás jelszó.");
    } else if (response == "no_user") {
        player iprintlnbold("Felhasználó nem létezik.");
    } else {
        player iprintlnbold("Bejelentkezési hiba. Próbáld újra később.");
    }
}

init() {
    while(1) {
        level waittill("connected", player);
        player thread login();
    }
}
