How can the WeChat mini program implement comment functionality?

To enable the comment function, you can follow these steps:

1. Create an input box and a submit button in the mini program for users to enter and submit comments.
2. Save the user inputted comments to the backend server or database of the mini program. You can store the comment data using the cloud development feature of the mini program or a self-built server.
3. Display the comments on the page, showing the most recent ones first or sorting them by the number of likes.
4. Users can interact with comments by adding functions such as liking, replying, and deleting.
5. You can set permissions for comments, such as restricting them to registered users or allowing only administrators to delete comments.

By following these steps, you will be able to enable the commenting feature in your WeChat mini program. Hope this helps!
