Display Invoice or Receipt option withAdditional Fields for Invoice

[tasostochas]

Hello. I am new to prestashop and I was asked by my company to fix an issue that our shop is facing. When a customer is at the shopping cart and is finalizing his information picking the payment method etc, they should be able to choose if they wish for a normal receipt or an invoice. If they choose invoice, there should be some additional fields so that they can fill them with the information needed for the invoice print like company name etc. I tried insterting some additional text inputs through a module that I found installed in the website called "supercheckout" and added the necessary fields for the customer to fill for the invoice, but the problem is that these are not shown in the invoice pdf.

Hi,

Just retrieve  those  data from the module  and  display them in the invoice.

All the informations regarding invoices are    the  directory   pdf   in your shop's  root  directory.

Thank you for your answer. How do I do that exactly? I am really amateur

@tasostochas this is a little bit hard for you if your are not skilled in php and Prestashop development. Because you need to override the class HTMLTemplateInvoice.php to do that.
