较多,这里给出一个简单的PHP微商城源码示例,包括商品展示、购物车和订单处理等功能,请根据实际需求进行修改和完善。
1、创建一个名为config.php
的文件,用于存储数据库连接信息:
<?php $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "micro_mall"; // 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); } ?>
2、创建一个名为products.php
的文件,用于展示商品列表:
<?php include 'config.php'; $sql = "SELECT * FROM products"; $result = $conn>query($sql); ?> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF8"> <title>微商城</title> </head> <body> <h1>商品列表</h1> <table border="1"> <tr> <th>ID</th> <th>名称</th> <th>价格</th> <th>操作</th> </tr> <?php while($row = $result>fetch_assoc()): ?> <tr> <td><?php echo $row['id']; ?></td> <td><?php echo $row['name']; ?></td> <td><?php echo $row['price']; ?></td> <td><a href="add_to_cart.php?id=<?php echo $row['id']; ?>">加入购物车</a></td> </tr> <?php endwhile; ?> </table> </body> </html> <?php $conn>close(); ?>
3、创建一个名为add_to_cart.php
的文件,用于将商品添加到购物车:
<?php session_start(); include 'config.php'; if (isset($_GET['id'])) { $product_id = $_GET['id']; if (!isset($_SESSION['cart'])) { $_SESSION['cart'] = array(); } if (!isset($_SESSION['cart'][$product_id])) { $_SESSION['cart'][$product_id] = 1; } else { $_SESSION['cart'][$product_id]++; } header('Location: cart.php'); } else { header('Location: products.php'); } ?>
4、创建一个名为cart.php
的文件,用于显示购物车内容:
<?php session_start(); include 'config.php'; ?> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF8"> <title>购物车</title> </head> <body> <h1>购物车</h1> <?php if (isset($_SESSION['cart']) && count($_SESSION['cart']) > 0): ?> <table border="1"> <tr> <th>ID</th> <th>名称</th> <th>价格</th> <th>数量</th> <th>操作</th> </tr> <?php foreach ($_SESSION['cart'] as $product_id => $quantity): ?> <?php $sql = "SELECT * FROM products WHERE id = $product_id"; $result = $conn>query($sql); $row = $result>fetch_assoc(); ?> <tr> <td><?php echo $row['id']; ?></td> <td><?php echo $row['name']; ?></td> <td><?php echo $row['price']; ?></td> <td><?php echo $quantity; ?></td> <td><a href="remove_from_cart.php?id=<?php echo $row['id']; ?>">移除</a></td> </tr> <?php endforeach; ?> </table> <?php else: ?> <p>购物车为空</p> <?php endif; ?> <a href="checkout.php">结算</a> </body> </html> <?php $conn>close(); ?>
5、创建一个名为remove_from_cart.php
的文件,用于从购物车中移除商品:
<?php session_start(); include 'config.php'; if (isset($_GET['id'])) { $product_id = $_GET['id']; if (isset($_SESSION['cart'][$product_id])) { unset($_SESSION['cart'][$product_id]); } header('Location: cart.php'); } else { header('Location: cart.php'); } ?>
6、创建一个名为checkout.php
的文件,用于处理订单:
<?php session_start(); include 'config.php'; ?> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF8"> <title>结算</title> </head> <body> <h1>结算</h1> <?php if (isset($_SESSION['cart']) && count($_SESSION['cart']) > 0): ?> <form action="submit_order.php" method="post"> <! 在这里添加表单字段,如姓名、地址等 > <input type="submit" value="提交订单"> </form> <?php else: ?> <p>购物车为空</p> <?php endif; ?> </body> </html>
7、创建一个名为submit_order.php
的文件,用于提交订单:
<?php session_start(); include 'config.php'; // 在这里处理订单逻辑,如保存订单信息到数据库等 // ... // 清空购物车 unset($_SESSION['cart']); ?> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF8"> <title>订单提交成功</title> </head> <body> <h1>订单提交成功</h1> <p>感谢您的购买!</p> </body> </html>
