Hello @radovand
Yes, of course, that’s possible. But the issue is not collecting the stars’ ratings, the most important is to display the results. You have different alternatives to store and display the results.
For example, you can edit the “cp_calculatedfieldsf_insert_in_database.php” file (https://cff.dwbooster.com/documentation#third-party-database) (distributed with the Developer and Platinum plugin versions) or use the “Database Queries for Calculated Fields Form” complementary plugin (https://cff-bundles.dwbooster.com/product/database-queries) to store the ratings as metadata of the posts, pages, or products you are evaluating. And, use the DS fields distributed with the Developer and Platinum plugin version to read the rating and display the corresponding stars (https://cff.dwbooster.com/blog/2019/02/14/ds)
Best regards.
