WordPress Plugin Modification

On this website students can purchase an ebook with the help of which he/she can get ready for a test (in the testing software where he gets access to right after the purchase). Our task was to add the functionality to Wordpress plugin «WP-checkout» and since now when make a purchase in the store, the plugin collects the necessary information in order to create a user in the testing software (http://yellowbook-cpe.com/test/). 1. We implemented the functionality for the collection of multiple sets of additional information (student name, student email) depending on the number of items in the shopping cart. 2. We made it possible to collect and send the information to the service http://yellowbook-cpe.com/test/ 3. Set up the reports system about all purchases available in the admin panel and for the site owner. 4. Implemented the functionality of the info collection and sending to the testing software for the payment via credit card.
