With the continuous development of the Internet, e-commerce has become one of the main ways for people to shop. In e-commerce, the development of mall websites is particularly important. Among them, the coupon function, as a marketing tool to attract consumers, has also become one of the necessary functions in the development of mall websites. This article will teach you step by step how to implement the coupon function through a PHP mall development tutorial.
- Determine the requirements and design of the coupon function
Before developing the coupon function, we first need to clarify the requirements and design of the function. Coupon functions generally include the generation, collection, use and expiration of coupons.
For the generation of coupons, different types of coupons can be generated according to the merchant's setting rules. For example, you can get 10 yuan off for purchases over 100 yuan or discounts for purchases over 200 yuan.
The process of receiving coupons can be done by the user clicking the receive button to add the coupon to the user's account.
During product settlement, users can choose to use the received coupons for deduction.
Expiration processing is to clean up expired coupons, and the system will automatically delete expired coupons from the user account.
- Database table design
The development of the coupon function cannot be separated from the support of the database. We need to design corresponding database tables to store coupon-related data.
For example, we can design a coupon table to save coupon information, including the coupon's name, face value, usage conditions, expiration time and other fields.
In addition, we also need to design a user_coupon table to associate users and coupons. In this table, we can save the user ID and the corresponding coupon ID.
- Generation and collection of coupons
In code implementation, we can generate coupons by writing a generateCoupon function. This function generates corresponding coupons based on the merchant's setting rules and saves them to the coupon table.
For the coupon collection process, we can provide users with a collection page, where users can click the receive button to add coupons to their accounts. After the user clicks the claim button, the PHP code can insert the corresponding coupon ID and user ID into the user_coupon table.
- Use of coupons
In the settlement page, we can query the user_coupon table by obtaining the user ID to obtain the coupon information that the user has received. Users can choose to use the coupons for discounts.
After the settlement is completed, we also need to update the data in the coupon table and user_coupon table to update the used coupon status.
- Coupon Expiration Processing
Scheduled tasks are a common way to implement coupon expiration processing. We can write a script and set up scheduled tasks to automatically detect and delete expired coupons.
In the script, we can determine whether the coupon has expired by querying the expiration time field in the coupon table. If it expires, delete the corresponding record.
- Front-end display and interaction
When developing the coupon function, front-end display and interaction cannot be ignored. We can design a simple and clear interface to display the coupons that users have received and provide corresponding operation buttons.
Through front-end frameworks such as jQuery, we can realize interactive operations such as coupon collection, use and deletion. For example, after the user clicks the claim button, the data can be sent to the backend through Ajax request to realize the coupon collection function.
Through the implementation of the above steps, we can complete a basic coupon function. In actual development, we can also expand and optimize according to actual needs, such as increasing the scope of use, limiting the number of uses, and other functions.
In short, through this PHP mall development tutorial, we can master the method of realizing the coupon function and provide a powerful marketing tool for the development of mall websites. At the same time, this is also an important way to improve user experience and promote sales growth. I hope this article can be helpful to PHP developers and better implement the coupon function.

To protect the application from session-related XSS attacks, the following measures are required: 1. Set the HttpOnly and Secure flags to protect the session cookies. 2. Export codes for all user inputs. 3. Implement content security policy (CSP) to limit script sources. Through these policies, session-related XSS attacks can be effectively protected and user data can be ensured.

Methods to optimize PHP session performance include: 1. Delay session start, 2. Use database to store sessions, 3. Compress session data, 4. Manage session life cycle, and 5. Implement session sharing. These strategies can significantly improve the efficiency of applications in high concurrency environments.

In PHP, you can use the session_name() function to configure the session name. The specific steps are as follows: 1. Use the session_name() function to set the session name, such as session_name("my_session"). 2. After setting the session name, call session_start() to start the session. Configuring session names can avoid session data conflicts between multiple applications and enhance security, but pay attention to the uniqueness, security, length and setting timing of session names.

The session ID should be regenerated regularly at login, before sensitive operations, and every 30 minutes. 1. Regenerate the session ID when logging in to prevent session fixed attacks. 2. Regenerate before sensitive operations to improve safety. 3. Regular regeneration reduces long-term utilization risks, but the user experience needs to be weighed.

Setting session cookie parameters in PHP can be achieved through the session_set_cookie_params() function. 1) Use this function to set parameters, such as expiration time, path, domain name, security flag, etc.; 2) Call session_start() to make the parameters take effect; 3) Dynamically adjust parameters according to needs, such as user login status; 4) Pay attention to setting secure and httponly flags to improve security.

The main purpose of using sessions in PHP is to maintain the status of the user between different pages. 1) The session is started through the session_start() function, creating a unique session ID and storing it in the user cookie. 2) Session data is saved on the server, allowing data to be passed between different requests, such as login status and shopping cart content.

How to share a session between subdomains? Implemented by setting session cookies for common domain names. 1. Set the domain of the session cookie to .example.com on the server side. 2. Choose the appropriate session storage method, such as memory, database or distributed cache. 3. Pass the session ID through cookies, and the server retrieves and updates the session data based on the ID.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
