# This is the database for all payable files.
# Files are located in download/ directory.
# Every line contain a file with following format:
# <filename>;<currency>;<price brutto>;<description>
#
# Example:
# program.zip;USD;10.0;Test Download
# Note: The Tax Rate is defined in config_global.inc.php
program.zip;USD;10.0;Test Download
After that copy your files into /payscript/download/ directory.
The Checkout Mask
If you access the payable file with https://mydomain.com/payscript/download/program.zip a checkout mask will be shown.
If you want to change the look & feel of the checkout mask, feel free to change the file checkout.php and/or the CSS files in css/ directory.
After the payment was successful the customer will get an email from shop email address (configurated in config_global.inc.php) with a secret download link.
Templates
The template of the shop email can be configurated in tpl/buyer_email.html and tpl/buyer_email_subject.txt
<p>Hello {fullname},</p>
<p>thanks for ordering <b>{description}</b> with price of {total}.</p>
<p>This is your Download URL: <a href="{download_url}">{download_url}</a></p>
