In the case they are paid, there’s not any problem. The fee will be included in the order review table before to checkout. The same happens with free add-ons. This means that you will see the fee in the review table and it’s price like $0.00.
This is not always the best thing. They are free, why should i show a cost? With a PHP snippet you can remove the cost only for free add-ons.
Since the release of the latest WooThemes’ extension, WooCommerce Photography, a lot of photographers asked me how to print EXIF data on the photograph page.
This feature is not included in WooCommerce Photography. I did some research about what exactly EXIF data is (I’m not a photographer at all) and if is possible to get them with PHP and turns out that it’s possible, and easy.
With this tutorial you will learn how to add a custom tab in the single product page to show EXIF data.
