instead reference EAN on pdf-invoice

[guest*]

I need to change the reference into EAN on invoices. Is this possible ? Does the invoice assign the variable ean13 ? I tried to change all "reference" into ean13 but it doesn't work.

Unfortunately, it's not that easy. The invoice gets the product information from the ps_order_detail table, not the ps_product table, so it doesn't include the EAN13. You'd need to modify the getProducts() function in classes/Order.php and add code like the following:

$product = new Product($row['product_id']);
$row['product_ean13'] = $product->ean13;
