Provide file download link after checkout complete

You could help test out http://drupal.org/project/commerce_views_pane which allows you to create any number of order views based checkout panes.
For example:

• clone the view commerce_cart_summary
• add the fields you want - ie product title, line item file field (commerce_file_line_item_files)
• Add a new views display of type "Commerce checkout pane"
• Visit "admin/commerce/config/checkout" and enable the new checkout pane on the page that you want

Thanks Recrit, as always you're a star! I'm installing commerce view pane now to test it.

Commerce File only allows downloads for logged in users but not for the current checkout.

Is this assertion true? I'm seeing references to anonymous users in other cases and there is nothing in the documentation that says it's not possible, so would appreciate some clarification. Thanks!

Please disregard my last question. Commerce File isn't designed for anonymous users. This might be helpful to others #1906478: Allow one Anonymous download after purchase

There's no patch here.

personally, for good business and to help the business grow, it is very necessary to have a customer register for an account so you can collect information on them, and deliver a better product, send out newsletters and gain a better understanding of your customers.

Here is a great module that makes the log in or create account step in the checkout easy on the customer and wont scare them away.

Hope this helps

I have just published 7.x-2.x which supports this:

Tagging for possible backport if a 7.x-1.x maintainer steps up.
