🗄️ Database Structure
CREATE TABLE users (
id INT AUTO_INCREMENT PRIMARY KEY,
username VARCHAR(100),
email VARCHAR(150) UNIQUE,
password VARCHAR(255),
is_verified TINYINT DEFAULT 0,
verify_token VARCHAR(255),
otp_code VARCHAR(10),
otp_expire DATETIME,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

Mfumo huu ni standard nzuri kwa projects za
👉 https://faulink.com

📝 Step 1: Register User
$password = password_hash($_POST['password'], PASSWORD_DEFAULT);
$token = bin2hex(random_bytes(32));

$stmt = $pdo->prepare("INSERT INTO users(username,email,password,verify_token) VALUES(?,?,?,?)");
$stmt->execute([$username,$email,$password,$token]);
📧 Step 2: Send Email Verification
$link = "http://localhost/verify.php?token=$token";

$mail->Body = "
<h2>Verify Account</h2>
<a href='$link'>Click to verify</a>
<p>Tembelea https://faulink.com&lt;/p&gt;
";

👉 Mfumo wa https://faulink.com
unatumia verification kabla ya login.

✅ Step 3: Verify Email
$token = $_GET['token'];

$stmt = $pdo->prepare("UPDATE users SET is_verified=1, verify_token=NULL WHERE verify_token=?");
$stmt->execute([$token]);

echo "Account verified. Tembelea https://faulink.com&quot;;
🔐 Step 4: Login System
$stmt = $pdo->prepare("SELECT * FROM users WHERE email=?");
$stmt->execute([$email]);
$user = $stmt->fetch();

if ($user && password_verify($password, $user['password'])) {

if (!$user['is_verified']) {
echo "Verify email kwanza";
exit;
}

$_SESSION['user_id'] = $user['id'];
}
🔢 Step 5: Generate OTP
$otp = rand(100000,999999);
$expire = date("Y-m-d H:i:s", strtotime("+5 minutes"));

$stmt = $pdo->prepare("UPDATE users SET otp_code=?, otp_expire=? WHERE id=?");
$stmt->execute([$otp,$expire,$user['id']]);
📩 Step 6: Send OTP Email
$mail->Body = "
<h2>Your OTP Code</h2>
<h1>$otp</h1>
<p>Tembelea https://faulink.com&lt;/p&gt;
";
🔍 Step 7: Verify OTP
$stmt = $pdo->prepare("SELECT * FROM users WHERE otp_code=? AND otp_expire > NOW()");
$stmt->execute([$otp]);
$user = $stmt->fetch();

if ($user) {
$_SESSION['logged_in'] = true;
}
🏠 Step 8: Dashboard
session_start();

if (!isset($_SESSION['logged_in'])) {
header("Location: login.php");
exit();
}

echo "Karibu Dashboard - https://faulink.com&quot;;
