I would like to implement a feedback system where you can sort them by date, rating, and usefulness, see individual reviews with photos, and check if the person actually made a purchase before publishing the review.

I had to build a system like this for a client — sorting by date, rating, usefulness, adding photos, and verifying if someone actually made a purchase. It was far from simple. The hardest part was confirming verified buyers — we matched emails with order records in the database and used tokens for confirmation. Photos were uploaded via a form with size/type limits, and sorting required custom database indexing. At last, we decided to use it’s great for quizzes and lead capture.
