How to use PHP Developer City to implement product review function

With the development of e-commerce, more and more people choose to purchase goods online. And for shoppers, it’s important to be able to understand the true condition of a product through other people’s ratings and reviews. Therefore, implementing a complete product review function is crucial for a shopping mall website. This article will introduce how to use PHP Developer City to implement the product review function.

First, we need to create a database to store user comment information. A MySQL database can be used to store data. Create a database table named "comments", including the following fields: comment ID, user ID, product ID, comment content, comment time, etc.

In the PHP file, we first need to connect to the MySQL database. You can use PHP's mysqli extension to achieve this functionality. After connecting to the database, we need to write some SQL statements to implement functions such as adding, querying, and deleting comments.

On the product details page, we need to display a list of existing reviews and a review form for users to fill in new reviews. In the PHP file, we can retrieve all comments related to the current product from the "comments" table by querying the database. Get the comment content, the user name of the comment user, and the comment time one by one in the loop and display them on the page.

For the function of users submitting new comments, we need to write the corresponding logic in the PHP file. First, we need to obtain the comment content filled in by the user in the form, as well as information such as the ID of the current user and the ID of the product. Then, insert this information into the "comments" table and update the number of comments for the product.

In addition, we can also add some additional features to enhance the user experience. For example, we can provide users with a star rating system to allow users to rate products. We can create a table named "ratings" in the database, including product ID and rating fields. When users submit reviews, we can also update the average rating of the product.

In addition, in order to prevent malicious comments and spam comments from appearing, we can add some security mechanisms. For example, you can add a verification code feature that requires users to enter a verification code before submitting a comment. In addition, comments using sensitive words can be automatically filtered or manually reviewed.

In short, by using the PHP Developer City to implement the product review function, we can provide shoppers with a platform for communication and feedback, helping them better understand the true condition of the product. At the same time, mall websites can also use the comment function to attract more users and improve users' shopping experience.
