## 📁 New Files Added

```

├── includes/
│   └── class-herepay-blocks-integration.php    # Block integration class
└── assets/
    └── blocks/
        ├── herepay-blocks.js                   # JavaScript for block checkout
        ├── herepay-blocks.css                  # CSS styling for blocks
        └── herepay-blocks.asset.php            # Asset dependencies
```

## 🔧 Enhanced Files

### **herepay-for-woocommerce.php**
- ✅ Added blocks integration loader
- ✅ Added blocks registration function  
- ✅ Declared `cart_checkout_blocks` compatibility
- ✅ Enhanced compatibility declarations

### **init.php** 
- ✅ Added `get_payment_post_data()` method for dual checkout support
- ✅ Enhanced `validate_fields()` for both classic and block checkout
- ✅ Enhanced `process_payment()` for both checkout types

## 🚀 How It Works

### **Automatic Detection**
The plugin automatically detects which checkout system is being used:

```php
// Classic Checkout
$_POST['herepay_bank_prefix']     // Direct form data

// Block Checkout  
$_POST['payment_data'][...]       // Structured data array
$_POST['payment_method_data'][...]// Alternative format
```

### **Unified Processing**
Both checkout types use the same backend processing:

```php
public function get_payment_post_data($key) {
    // Try classic checkout first
    if (isset($_POST[$key]) && !empty($_POST[$key])) {
        return sanitize_text_field($_POST[$key]);
    }
    
    // Fallback to block checkout formats
    // ... handles multiple block data structures
}
```

## 📋 Testing Instructions
