Steps to implement the store credit rating star display function in PHP Developer City

With the rapid development of e-commerce, more and more people choose to shop online. In the process of online shopping, consumers are most concerned about the credibility and reputation of merchants. In order to allow consumers to better choose reputable merchants, many malls have introduced store credit evaluation functions. One of the most common forms is to use star rating to display ratings. This article will introduce the steps to implement the store credit rating star display function in a mall developed in PHP.

Step 1: Database design and creation
First, we need to design a database to store store and evaluation-related information. Two tables need to be created in the database. One is the store information table, which stores the basic information of the store, such as store name, store owner name, contact information, etc. The other table is a store evaluation table, which is used to store consumer evaluation information about the store, including fields such as store ID, evaluator name, evaluation time, evaluation content, and evaluation score.

Step 2: Page design and layout
In PHP development, we need to design corresponding pages to display the basic information and evaluation scores of the store. Usually, we can embed a star rating module on the store homepage. In this module, the average rating of the store will be displayed, and the rating level will be displayed in the form of stars. At the same time, we can also display the specific rating details and evaluation content from consumers on the store details page.

Step 3: Calculate ratings and display
When consumers evaluate a store, we need to store the rating data into the database and perform corresponding calculations. Before storing in the database, we need to verify whether the score is legal and perform data filtering and formatting to prevent possible malicious attacks and incorrect data entry. When calculating the average rating, you can get the average rating by looping through the rating fields in the store review table, summing them, and dividing them by the total number of reviews. At the same time, we can also give different colors to the stars in the rating display module according to the numerical range of the rating, so that consumers can intuitively understand the credibility level of the store.

Step 4: Display and management of evaluation content
The display of evaluation content can be performed on the store details page for the convenience of consumers to view and refer to. When displaying the evaluation content, we can sort it according to the evaluation time and display it in pages to prevent too much evaluation content from affecting the page loading speed. At the same time, in the display of evaluation content, we can also add some keyword filtering and sensitive word blocking functions to exclude inappropriate evaluation content.

Step 5: Management of store credit evaluation
As the administrator of the mall, we need to manage and maintain the store credit evaluation. We can add a management page to view, review, modify and delete store reviews. During the review, we can review the evaluation content to prevent the spread of false information. When modifying and deleting, we need to add corresponding verification mechanisms to ensure the legality of the operation.

To sum up, the steps to implement the store credit evaluation star display function in a PHP-developed mall mainly include: database design and creation, page design and layout, calculation of scores and display, display and evaluation content Management and store credit evaluation management. Through the implementation of these steps, we can provide consumers with reliable store credit evaluation information, help them better choose honest merchants, and also enhance the credibility and competitiveness of the mall.
