Invoice number in email template

[wiros]

I like to get the invoice number into an email template like this is done with order number {ID_order}

 

I trie to add {ID_invoice} or {invoice_number} but it does not result in the correct number when the email is send to the customer.

 

Does anyone know how to do this?

See data injected to email templates in /classes/PaymentModule.php, below the line with:

 

// Send an e-mail to customer ......

 

There is no invoice number there, but you can add your own.
