PHP Mall Coupon Development: Steps and Tips from Scratch

Introduction:

Coupons are widely used in modern e-commerce, Not only do they attract customers to buy goods, but they also increase sales. PHP is a powerful programming language that can be used to develop a variety of powerful business applications, including coupon systems. In this article, we will explore the steps and techniques to develop a PHP mall coupon from scratch.

Step 1: Requirements Analysis

Before developing any application, you first need to conduct a requirements analysis. In the coupon system, you need to be clear about the following points:

1. Users should be able to register and log in to the system;
2. Be able to browse available coupons;
3. Users can select and add coupons to their shopping carts;
4. The system should be able to validate and apply coupons;
5. Users can complete purchases and pay;
6. Administrators can Add, edit and delete coupons.

Step 2: Database design

Once the requirements analysis is determined, the next step is to design the database structure. In this example, you need to consider the following tables:

1. User table: used to store user details such as name, email and password;
2. Coupon table : Used to store coupon details, such as coupon code, discount amount and validity period;
3. User Coupon Table: Used to store the relationship between users and coupons, such as user ID and coupon ID;
4. Shopping cart table: used to store the product information of the user's current shopping cart.

Step 3: User registration and login

In PHP, you can use sessions to manage user login status. When a user registers, you can insert their details into the users table. When a user logs in, you can verify the username and password they provided and create a session once verified.

Step 4: Coupon browsing and selection

In the coupon system, you need to write code to get the available coupons from the database. These coupons can be filtered according to different categories and displayed on the user interface for users to select.

Step Five: Coupon Validation and Application

When a user adds a coupon to their shopping cart, you need to write code to validate and apply the coupon. You can verify the validity of a coupon by checking its expiry date, owner, and other fields. You can then apply the coupon's discount amount to your cart's total price.

Step Six: Purchase and Pay

Once the user has completed all selections in the shopping cart, they can proceed to the checkout and payment page. On this page, you need to write code to calculate the amount the user needs to pay and provide different payment methods for the user to choose from.

Step 7: Administrator Functions

As an administrator, you may need to add, edit and delete coupons. You can write some code to implement these functions and provide an admin interface for administrators to use.

Tips 1: Use frameworks

PHP has many excellent development frameworks, such as Laravel, Symfony, etc. Using frameworks can help you develop applications faster and easier because they provide functionality and components that are already encapsulated.

Tips 2: Security considerations

When developing a coupon system, it is very important to ensure the security of the code. Please ensure that user-supplied data is properly validated and filtered to prevent security vulnerabilities such as SQL injection, cross-site scripting attacks, etc.

Conclusion:

Through the steps and techniques in this article, I hope you can develop a powerful PHP shopping mall coupon system from scratch. Remember, requirements analysis, database design, and security considerations are key elements of a successful coupon system. Good luck with your development!
