In an e-commerce website, when built using PHP, the following fields are usually required:
User information field: including user Name, password, email address, name, contact information, etc.
Product information fields: including product name, price, description, inventory quantity, product classification, SKU code (if any), etc.
Shopping cart field: used to store product information added to the shopping cart by the user, usually including product ID, quantity, price, subtotal, etc.
Order information field: used to store user-generated order information, including order number, purchased product list, total order amount, shipping address, payment method, etc.
Payment information field: used to store user payment-related information, including payment status, payment time, payment method, payment amount, etc.
Logistics information field: used to store the logistics information of the order, including courier company, waybill number, delivery time, receipt time, etc.
Evaluation and comment fields: used for users to evaluate and comment on products, including ratings, comment content, comment time, etc.
User delivery address field: used to store the user's delivery address information, including name, contact information, province, city, detailed address, etc.
The above fields are just some common examples. The design of specific fields needs to be determined based on the specific needs and business processes of the e-commerce website. In actual development, you also need to consider the relationship between the database design and data tables, and use PHP code to process and operate these fields.
