Conditional Invoice or Manual
-
Hello to everyone. I have to say using your plugin is amazing. I am trying to customize the way it works. I will present my useage case:
First of all, I want to always create packing slips on every order (this is working).
Secondly I have a custom checkbox where a user selects if he wants an invoice. I want the plugin to create an invoice when this checkbox is selected. If this is not possible, I want to create an invoice manualy for these orders. Finaly, is there a way to cancel an invoice?
(In Greece we need invoices for business clients).
Any help would be really appreciated, thank you in advance.

Hello @progounick
For the checkbox request, try this (change the meta name and value with yours):
add_filter('wpo_wcpdf_document_is_enabled', 'wpo_wcpdf_enable_invoice_on_checkbox', 10, 2); function wpo_wcpdf_enable_invoice_on_checkbox($enabled, $document_type) { if( $document_type == 'invoice' ) { $enabled = false; $order = wc_get_order(get_the_id()); $checkbox = $order->get_meta('checkbox_meta_name'); // Change the meta name to your's if( !empty($checkbox) && $checkbox == 'some_value' ) { // Change to your checkbox value $enabled = true; } } return $enabled; }If you never worked with filters/actions please read this documentation: How to use filters
About the cancel invoice, by default our plugin keeps the original order data to meet accounting standards, but we have the Professional extension that adds a new document called “Credit Note”. You could attach it to a refunded order status and it will generate a new document like a “negative invoice”.
