3. Comment submission and saving

After the user fills in the comment content in the comment box, click the submit button. Store review content and related data in the database through PHP code. At the same time, add 1 to the number of reviews for this product.

5. Reply Implementation

When the user clicks the reply button under a comment, the reply box is loaded asynchronously through Ajax technology, and the user's name of the replied user is displayed in the reply box. Nickname and comment content. Users can fill in the reply content in the reply box and click the submit button.
