This addon extends the functionality of the PDF Invoices & Packing Slips for WooCommerce plugin by allowing you to add custom handlers to the UBL document format. Handlers can be positioned before or after existing handlers, providing flexibility in customizing the UBL document generation process.
git clone [email protected]:wpovernight/woocommerce-pdf-ips-ubl-extender.gitEnsure your custom handler classes are placed inside the includes/handlers directory with the following namespace:
namespace WPO\WC\UBL\Extender\Handlers;Your custom handlers should extend the main plugin abstract class \WPO\WC\UBL\Handlers\UblHandler.
Example of a custom handler:
<?php
namespace WPO\WC\UBL\Extender\Handlers;
use WPO\WC\UBL\Handlers\UblHandler;
class CustomHandler extends UblHandler {
public function handle() {
// Your custom handling logic here
}
}
?>When you add a new handler, you must include it inside the add_handlers() function in the main addon plugin file woocommerce-pdf-ips-ubl-extender.php. Here is how you can do it:
public function add_handlers( array $format ): array {
$custom_handler = array(
'enabled' => true,
'handler' => \WPO\WC\UBL\Extender\Handlers\CustomHandler::class,
);
$format = $this->insert_handler_at_key( $format, 'customhandler', $custom_handler, 'issuedate', 'after' ); // Insert after 'issuedate'
return $format;
}After adding new handler classes, make sure to dump the Composer autoload to include the new classes:
