How does the Sync between Moodle and WordPress actually work while using Edwiser Bridge?
After you have set up Edwiser Bridge successfully by following this documentation - https://edwiser.org/bridge/documentation/
Once you have followed the documentation, test the connection and then synchronize the courses. All the courses on the Moodle site are synced to the Wordpress site, where a 'courses' page is created from where the users can purchase the course. After purchasing the course, the user will be redirected to the My Courses page and as they click on the enrolled course they will be redirected to the Moodle site.
Please note only your courses and its descriptions are synced to the Wordpress site from the Moodle site, not the course image, course price and existing users.
