1. Extending Services (Airtime, Data, Cable, etc.)
All services in VTUPress inherit from the `Vtupress_services` abstract class (which itself extends `Vtupress_Process_Transactions`).
Base Class: `Vtupress_services`
**File:** `includes/services_class.php`
To create a brand new service (e.g., “Electricity Cards” or “International Topup”):
1. Create a new class extending `Vtupress_services` and implementing `Vtupress_History_Interface`.
2. Register your class into the VTUPress ecosystem using the `vtupress_service_registry` filter.
Example: Adding a Custom Service
```php
class Custom_Service extends Vtupress_services implements Vtupress_History_Interface {
public function __construct() {
$this->id = 'custom_service';
$this->name = 'Custom Service';
$this->icon = 'fa-solid fa-bolt';
// Initialize other properties...
}
public function process_transaction($payload) {
// Implement your custom API connection and processing logic here
}
}
// Register the service
add_filter('vtupress_service_registry', function($registry) {
$registry['custom_service'] = 'Custom_Service';
return $registry;
});
```—
