微商城PHP源码是一种基于PHP语言开发的电子商务平台源代码,用于创建和管理在线商城。
由于微商城PHP源码涉及到的内容较多,这里给出一个简单的示例,包括用户注册、登录、商品列表展示和购物车功能,请根据实际需求进行修改和完善。
1、创建一个数据库表用于存储用户信息:
CREATE TABLEusers
(id
int(11) NOT NULL AUTO_INCREMENT,username
varchar(255) NOT NULL,password
varchar(255) NOT NULL,id
) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
2、创建一个数据库表用于存储商品信息:
CREATE TABLEproducts
(id
int(11) NOT NULL AUTO_INCREMENT,name
varchar(255) NOT NULL,price
decimal(10,2) NOT NULL,description
text, PRIMARY KEY (id
) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
3、创建一个数据库表用于存储购物车信息:
CREATE TABLEcart
(id
int(11) NOT NULL AUTO_INCREMENT,user_id
int(11) NOT NULL,product_id
int(11) NOT NULL,quantity
int(11) NOT NULL, PRIMARY KEY (id
), FOREIGN KEY (user_id
) REFERENCESusers
(id
), FOREIGN KEY (product_id
) REFERENCESproducts
(id
) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
4、创建用户注册页面(register.php):
<!DOCTYPE html> <html> <head> <title>用户注册</title> </head> <body> <h1>用户注册</h1> <form action="register_action.php" method="post"> 用户名: <input type="text" name="username"><br> 密码: <input type="password" name="password"><br> 邮箱: <input type="email" name="email"><br> <input type="submit" value="注册"> </form> </body> </html>
5、创建用户注册处理脚本(register_action.php):
<?php $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "myDB"; // 创建连接 $conn = new mysqli($servername, $username, $password, $dbname); // 检测连接 if ($conn>connect_error) { die("连接失败: " . $conn>connect_error); } $username = $_POST['username']; $password = $_POST['password']; $email = $_POST['email']; $sql = "INSERT INTO users (username, password, email) VALUES ('$username', '$password', '$email')"; if ($conn>query($sql) === TRUE) { echo "注册成功"; } else { echo "Error: " . $sql . "<br>" . $conn>error; } $conn>close(); ?>
6、创建用户登录页面(login.php):
<!DOCTYPE html> <html> <head> <title>用户登录</title> </head> <body> <h1>用户登录</h1> <form action="login_action.php" method="post"> 用户名: <input type="text" name="username"><br> 密码: <input type="password" name="password"><br> <input type="submit" value="登录"> </form> </body> </html>
7、创建用户登录处理脚本(login_action.php):
<?php session_start(); $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "myDB"; // 创建连接 $conn = new mysqli($servername, $username, $password, $dbname); // 检测连接 if ($conn>connect_error) { die("连接失败: " . $conn>connect_error); } $username = $_POST['username']; $password = $_POST['password']; $sql = "SELECT * FROM users WHERE username='$username' AND password='$password'"; $result = $conn>query($sql); if ($result>num_rows > 0) { $_SESSION['username'] = $username; header("Location: product_list.php"); } else { echo "用户名或密码错误"; } $conn>close(); ?>
8、创建商品列表页面(product_list.php):
<?php session_start(); if (!isset($_SESSION['username'])) { header("Location: login.php"); exit; } ?> <!DOCTYPE html> <html> <head> <title>商品列表</title> </head> <body> <h1>商品列表</h1> <a href="cart.php">查看购物车</a> | <a href="logout.php">退出登录</a> <table border="1"> <tr> <th>商品名称</th> <th>价格</th> <th>操作</th> </tr> <?php $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "myDB"; // 创建连接 $conn = new mysqli($servername, $username, $password, $dbname); // 检测连接 if ($conn>connect_error) { die("连接失败: " . $conn>connect_error); } $sql = "SELECT * FROM products"; $result = $conn>query($sql); if ($result>num_rows > 0) { while($row = $result>fetch_assoc()) { echo "<tr><td>" . $row["name"]. "</td><td>" . $row["price"]. "</td><td><a href='add_to_cart.php?product_id=".$row["id"]."'>加入购物车</a></td></tr>"; } } else { echo "0 结果"; } $conn>close(); ?> </table> </body> </html>
9、创建添加商品到购物车的脚本(add_to_cart.php):
<?php session_start(); if (!isset($_SESSION['username'])) { header("Location: login.php"); exit; } $product_id = $_GET['product_id']; $user_id = $_SESSION['user_id']; // 假设已经获取到用户ID,实际应用中需要从数据库中查询 $quantity = 1; // 默认购买数量为1,可以根据需要进行修改 $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "myDB"; // 创建连接 $conn = new mysqli($servername, $username, $password, $dbname); // 检测连接 if ($conn>connect_error) { die("连接失败: " . $conn>connect_error); } $sql = "INSERT INTO cart (user_id, product_id, quantity) VALUES ($user_id, $product_id, $quantity)"; if ($conn>query($sql) === TRUE) { echo "商品已添加到购物车"; } else { echo "Error: " . $sql . "<br>" . $conn>error; } $conn>close(); ?>
10、创建购物车页面(cart.php):
<?php session_start(); if (!isset($_SESSION['username'])) { header("Location: login.php"); exit; } ?> <!DOCTYPE html> <html> <head> <title>购物车</title> </head> <body> <h1>购物车</h1> <a href="product_list.php">返回商品列表</a> | <a href="logout.php">退出登录</a> <table border="1"> <tr> <th>商品名称</th> <th>价格</th> <th>数量</th> <th>操作</th> </tr> <?php $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "myDB"; $user_id = $_SESSION['user_id']; // 假设已经获取到用户ID,实际应用中需要从数据库中查询 // 创建连接 $conn = new mysqli($servername, $username, $password, $dbname); // 检测连接 if ($conn>connect_error) { die("连接失败: " . $conn>connect_error); } $sql = "SELECT p.name, p.price, c.quantity FROM cart c INNER JOIN products p ON c.product_id = p.id WHERE c.user_id = $user_id"; $result = $conn>query($sql); if ($result>num_rows > 0) { while($row = $result>fetch_assoc()) { echo "<tr><td>" . $row["name"]. "</td><td>" . $row["price"]. "</td><td>" . $row["quantity"]. "</td><td><a href='remove_from_cart.php?product_id=".$row["product_id"]."'>移除</a></td></tr>"; } } else { echo "购物车为空"; } $conn>close(); ?> </table> </body> </html>
