How do I add text to the invoice?

Hello,

A few of my customers are having some issues with the digital download feature in Zencart and I wanted to add in a note in the invoice to clear up some of the confusion. How can I add / change the text currently there?

My invoice currently reads:
Order Confirmation from SemiWiki Store

customer name

Thanks for shopping with us today!

You can add text to your checkout_success.php here:

includes/languages/english/YOUR_TEMPLATE/checkout_success.php

Hope that helps,

I assume you mean the email confirmations?

includes\classes\order.php
email\email_template_checkout.html

Or you could make a simple language-file override. If the file /includes/languages/english/YOUR_TEMPLATE/checkout_process.php doesn't exist (where YOUR_TEMPLATE is the name of your custom template), copy /includes/languages/english/checkout_process.php to that location and edit the copied file, changing the following definition:

define('EMAIL_THANKS_FOR_SHOPPING','Thanks for shopping with us today!' . "\n\n" . 'Note: If your order includes digital downloads, <more instructions here>.');
