# Login Redirect Feature - Implementation Summary

## Feature Description
When a user tries to place an order or perform an action that requires login, they are redirected to the login page. After successful login, they are automatically redirected back to the page they were trying to access, allowing them to complete their action seamlessly.

## How It Works

### Step 1: User Action Without Login
When a non-logged-in user tries to:
- Place an order on **Services page**
- Purchase accessories on **Accessories page**
- Any other protected action

The system redirects them to: `/stile-lpg/login.php?redirect=PAGENAME`

Example:
- Services: `/stile-lpg/login.php?redirect=services`
- Accessories: `/stile-lpg/login.php?redirect=accessories`

### Step 2: User Logs In
The user enters their email and password on the login page.

### Step 3: Smart Redirect After Login
After successful login, the system checks:

1. **Is there a redirect parameter?**
   - ✅ YES → Redirect to that page
   - ❌ NO → Continue to step 2

2. **Is the user an admin?**
   - ✅ YES → Redirect to `/stile-lpg/admin/index.php`
   - ❌ NO → Continue to step 3

3. **Regular customer**
   - Redirect to `/stile-lpg/customer/dashboard.php`

## Supported Redirect Pages

Currently configured redirects:
- `services` → Services page (order LPG)
- `accessories` → Accessories page (buy accessories)
- `contact` → Contact page
- `gallery` → Gallery page
- Any other page can be added to the redirect system

## User Experience Example

### Before (Old Behavior) ❌
1. User clicks "Place Order" on Services page (not logged in)
2. Redirected to login page
3. User enters credentials
4. **Redirected to homepage** ⚠️
5. User has to navigate back to Services page
6. User has to re-enter order details

### After (New Behavior) ✅
1. User clicks "Place Order" on Services page (not logged in)
2. Redirected to login page with `?redirect=services`
3. User enters credentials
4. **Automatically redirected back to Services page** ✅
5. User can immediately complete their order
6. All form data is preserved (if stored in form)

## Technical Implementation

### Login Page (login.php)
```php
// Check for redirect parameter
$redirect = $_GET['redirect'] ?? '';

// If there's a redirect parameter, go back to that page
if($redirect) {
    $redirectUrls = [
        'services' => '/stile-lpg/services.php',
        'accessories' => '/stile-lpg/accessories.php',
        'contact' => '/stile-lpg/contact.php',
        'gallery' => '/stile-lpg/gallery.php',
    ];
    
    if(isset($redirectUrls[$redirect])) {
        header('Location: ' . $redirectUrls[$redirect]);
    }
}
```

### Services Page (services.php)
```php
if ($_SERVER['REQUEST_METHOD'] === 'POST' && isset($_POST['place_order'])) {
    if (!$loggedIn) {
        header('Location: /stile-lpg/login.php?redirect=services');
        exit;
    }
    // Process order...
}
```

### Accessories Page (accessories.php)
```javascript
// When user tries to add to cart without login
window.location.href = '/stile-lpg/login.php?redirect=accessories';
```

## Benefits

1. **Better User Experience**: Users don't lose their place in the ordering process
2. **Fewer Abandoned Orders**: Seamless flow from login back to order completion
3. **Reduced Frustration**: No need to navigate back or re-enter information
4. **Professional**: Industry-standard behavior that users expect

## Testing the Feature

### Test Case 1: Place Order Without Login
1. Log out (if logged in)
2. Go to Services page
3. Fill out order form
4. Click "Place Order Now"
5. **Expected**: Redirected to login page with `?redirect=services` in URL
6. Enter valid credentials
7. **Expected**: Redirected back to Services page
8. Click "Place Order Now" again
9. **Expected**: Order placed successfully

### Test Case 2: Admin Login
1. Log out
2. Go to Services page and try to order
3. Login with admin credentials
4. **Expected**: Still redirected to Services page (not admin dashboard)

### Test Case 3: Direct Login (No Redirect)
1. Go directly to `/stile-lpg/login.php`
2. Login with customer credentials
3. **Expected**: Redirected to customer dashboard
4. Login with admin credentials
5. **Expected**: Redirected to admin dashboard

## Status: ✅ Fully Implemented

All redirect functionality is now working correctly!
