Detailed explanation of the design of shopping mall shopping process developed with PHP

In today's e-commerce era, the development of shopping websites has become the focus of many developers. This article will introduce in detail how to use PHP to develop a shopping mall shopping website, and give corresponding code examples.

1. Demand analysis

First of all, we need to analyze the main needs of the mall shopping website:

User login and registration: Users can log in to the mall by registering an account , or log in using your existing account.
Product browsing and search: Users can browse the products in the mall and find specific products through the search function.
Shopping cart management: Users can add items to the shopping cart, select the purchase quantity, and manage the selected items in the shopping cart.
Order management: Users can view the orders that have been placed and perform operations on the orders, such as canceling orders, viewing order details, etc.
Payment function: Users can choose the payment method and complete the payment operation.

2. Database design

Create three tables in the MySQL database to store user information, product information and order information.

User table (User):

Field:

user_id: user ID
username: username
password: Password
email: Email

Product table (Product):

Field:

product_id: Product ID
product_name: Product name
price: Product price
stock: Inventory quantity

Order table (Order):

Field:

order_id: order ID
user_id: user ID (foreign key)
product_id: product ID (foreign key)
quantity: purchase quantity
total_price: total order price
order_time: order time

3. Page design and code examples

User login and registration page

<?php
session_start();

// 登录
if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST['submit_login'])) {
    // 处理登录验证逻辑
    // ...
}

// 注册
if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST['submit_register'])) {
    // 处理注册逻辑
    // ...
}
?>

<!DOCTYPE html>
<html>

<head>
    <title>用户登录和注册</title>
</head>

<body>
    <h1>用户登录</h1>
    <form action="" method="POST">
        <label for="username">用户名:</label>
        <input type="text" name="username"><br>
        <label for="password">密码:</label>
        <input type="password" name="password"><br>
        <input type="submit" name="submit_login" value="登录">
    </form>

    <h1>用户注册</h1>
    <form action="" method="POST">
        <label for="username">用户名:</label>
        <input type="text" name="username"><br>
        <label for="password">密码:</label>
        <input type="password" name="password"><br>
        <label for="email">邮箱:</label>

    // 获取用户输入的搜索关键字
    $keyword = $_POST['keyword'];
    // 根据关键字查询商品
    $query = "SELECT * FROM Product WHERE product_name LIKE '%$keyword%'";
    $result = mysqli_query($conn, $query);
}
?>

<!DOCTYPE html>
<html>

<head>
    <title>商品浏览和搜索</title>
</head>

<body>
    <h1>商品浏览</h1>
    <?php while ($row = mysqli_fetch_assoc($result)) { ?>
    <div>
