## 🔐 Security & Validation

### Registration Security:
✅ **Customer-Only** - No admin option in register  
✅ **Password Hashing** - Uses PASSWORD_DEFAULT (bcrypt)  
✅ **Email Validation** - FILTER_VALIDATE_EMAIL  
✅ **Prepared Statements** - All SQL injection prevented  
✅ **Duplicate Check** - Cannot register same email twice  
✅ **Input Sanitization** - trim() and htmlspecialchars()  

### Login Security:
✅ **Role-Based** - Only matches specified role with email  
✅ **Prepared Statements** - SQL injection protected  
✅ **Password Verify** - password_verify() for comparison  
✅ **Session Validation** - Checks sessions on all pages  
✅ **XSS Prevention** - All output escaped  
✅ **No SQL Exposed** - Graceful error messages  

### Admin Protection:
✅ **Cannot Register as Admin** - Hardcoded in register.php  
✅ **Manual Creation Only** - Database insert or admin panel  
✅ **Role Verification** - Login checks role in database  
✅ **Session Role** - Role stored in $_SESSION  

---

## 📊 Technical Implementation

### Login Page - Role Selection Code:

**HTML (Button Interface):**
```html
<div style="display: flex; gap: 10px; margin-bottom: 25px;">
    <button type="button" class="role-btn-admin active" 
            onclick="selectRole('admin')" 
            style="...gold gradient...">
        <i class="fas fa-shield-alt"></i> Admin
    </button>
    <button type="button" class="role-btn-customer" 
            onclick="selectRole('customer')" 
            style="...white background...">
        <i class="fas fa-user-circle"></i> Customer
    </button>
</div>
<input type="hidden" id="user_role" name="user_role" value="admin">
```

**JavaScript (Button Toggle):**
```javascript
function selectRole(role) {
    const adminBtn = document.querySelector('.role-btn-admin');
    const customerBtn = document.querySelector('.role-btn-customer');
    const roleInput = document.getElementById('user_role');

    if (role === 'admin') {
        // Highlight admin button
        adminBtn.style.background = 'linear-gradient(135deg, #D4A574 0%, #b8905a 100%)';
        adminBtn.style.color = 'white';
        adminBtn.style.boxShadow = '0 4px 12px rgba(212, 165, 116, 0.3)';
        
        // Deactivate customer button
        customerBtn.style.background = 'white';
        customerBtn.style.color = '#333';
        customerBtn.style.boxShadow = 'none';
    } else {
        // Vice versa for customer
        customerBtn.style.background = 'linear-gradient(135deg, #D4A574 0%, #b8905a 100%)';
        adminBtn.style.background = 'white';
        // ... other styles
    }
    
    roleInput.value = role;
}
```

### Register Page - Customer-Only Code:

**PHP (Force Customer Role):**
```php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $name = trim($_POST['name'] ?? '');
    $email = trim($_POST['email'] ?? '');
    $phone = trim($_POST['phone'] ?? '');
    $password = $_POST['password'] ?? '';
    $confirm_password = $_POST['confirm_password'] ?? '');
    
    // FORCE customer role - Admin cannot register
    $user_role = 'customer';
    
    // ... validation and insert ...
}
```

**HTML (Info Box):**
```html
<div style="background: linear-gradient(135deg, #E8D5C4 0%, #F0E6D8 100%); 
            padding: 12px 16px; border-radius: 8px; 
            margin-bottom: 20px; border-left: 4px solid #D4A574;">
    <i class="fas fa-check-circle" style="color: #D4A574;"></i>
    Registering as: <strong>Customer</strong>
</div>
