# Admin Authentication System - Complete! ✅

## 🎉 **What's Working:**

### 1. **Login System**
- ✅ Admin can login at `/admin/login.php`
- ✅ Username: `admin`
- ✅ Password: `Crm@dmin!@#`
- ✅ Password verification with bcrypt
- ✅ Session management
- ✅ Last login tracking

### 2. **Authentication Protection**
- ✅ Admin dashboard (`index.php`) is now protected
- ✅ Non-logged-in users are redirected to login page
- ✅ Session-based authentication

### 3. **API Endpoints**
- ✅ `/admin/api/login.php` - Login endpoint
- ✅ `/admin/api/logout.php` - Logout endpoint
- ✅ `/admin/api/check-auth.php` - Check authentication status

### 4. **Authentication Middleware**
- ✅ `/admin/includes/auth.php` - Reusable auth functions

## 📝 **How to Use:**

### **Protect Any Admin Page:**
Add this at the top of any PHP file you want to protect:

```php
<?php
require_once 'includes/auth.php';
requireAuth();
?>
```

### **Get Current Admin User:**
```php
<?php
$admin = getCurrentAdmin();
echo "Welcome, " . $admin['full_name'];
?>
```

### **Check User Role:**
```php
<?php
if (hasRole('super_admin')) {
    // Show admin-only features
}
?>
```

### **Require Specific Role:**
```php
<?php
requireRole('super_admin'); // Will redirect if user doesn't have this role
?>
```

## 🔐 **Available Functions:**

1. **`isAdminLoggedIn()`** - Returns true/false
2. **`requireAuth()`** - Redirects to login if not logged in
3. **`getCurrentAdmin()`** - Returns current user data
4. **`hasRole($role)`** - Check if user has specific role
5. **`requireRole($role)`** - Require specific role or redirect

## 🚀 **Next Steps:**

To protect other admin pages, add the authentication check to:
- `products.php`
- `orders.php`
- `customers.php`
- `blogs.php`
- etc.

## ✅ **Test It:**

1. **Logout** (if logged in)
2. **Try to access** `/admin/index.php`
3. **You should be redirected** to `/admin/login.php`
4. **Login** with credentials
5. **You should be redirected** back to dashboard!

**Status:** ✅ COMPLETE AND WORKING!
