How to use the limited time discount function of PHP Developer City

With the rapid development of e-commerce, online shopping malls have become one of the main ways for people to shop. To occupy a place in the market, a good mall must provide a variety of discounts to attract consumers. Among them, limited-time discounts are a popular and effective promotion method. This article will focus on how to use the limited-time discount function of the PHP Developer City.

1. Design the mall database

Before developing the limited-time discount function of the PHP mall, we need to design a mall database. The mall database can contain the following data tables:

1. Product table: product ID, product name, product description, unit price, inventory quantity and other fields.
2. Order table: fields such as order ID, product ID, purchase quantity, purchase time, order status, etc.
3. Discount table: Discount ID, discount name, start time, end time, discount proportion and other fields.
4. Discount product table: Discount ID, product ID, discount amount and other fields.

2. Implement the limited-time discount function

With the database, we can start to implement the limited-time discount function. The following are specific operations:

1. Add discount: Merchants can add a discount through the control panel, and then select the effective time and discount proportion. After adding the discount successfully, we need to store the discount information in the database.
2. Set discounted products: Merchants need to select the products participating in the discount in the control panel and calculate the discounted price based on the discount proportion. At this time, we need to store the discounted product information in the database.
3. Display discounted products: The mall homepage can display currently effective discounted products to attract consumers. In PHP, we can use query statements to filter out the information of all discounted products in the current time period, and present the display effect through web templates.
4. Calculate shopping cart discount: If a consumer adds discounted items to the shopping cart, we need to calculate the discounted price and display it in the shopping cart. To do this, we need to calculate and display the discounted price through PHP code on the product details page and shopping cart page.
5. Order discount: When consumers place an order, we need to check the product inventory and update the corresponding order status. If the discounted item is out of stock, the user needs to be prompted. If there is sufficient inventory, we will need to update the order data to reflect the discount amount on the order.

3. Enhance user experience

Considering to improve user experience, we can add the following functions:

1. Add countdown: display discounts on the mall page When purchasing products, we can add a countdown function to let consumers clearly know the remaining time of the discount event.
2. Push discount information: The mall can push discount product information to users via email or SMS, so that users can more easily obtain discount product information.
3. Generate discount codes: The mall can randomly generate a set of discount codes and provide users with the option to enter discount codes when checking user settlement to achieve additional discounts.

4. Summary

As we can see, limited-time discount activities are a very effective way of promotion. Using the limited-time discount function of PHP Developer City can help merchants enhance their competitiveness and attract more consumers. While this requires some challenging programming, the effort will bring you unparalleled benefits, especially focusing on user experience as much as possible.
