网站会员系统源码通常包括用户注册、登录、资料管理、权限控制等功能模块。
用户注册、用户登录、用户信息管理、权限管理等,以下是一个简单的PHP和MySQL实现的会员系统示例:
1、数据库表结构设计:
CREATE TABLEusers
(id
int(11) NOT NULL AUTO_INCREMENT,username
varchar(255) NOT NULL,password
varchar(255) NOT NULL,role
enum('admin','user') NOT NULL DEFAULT 'user', PRIMARY KEY (id
), UNIQUE KEYusername
(username
), UNIQUE KEY
2、连接数据库的配置文件(config.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: " . $conn>connect_error); } ?>
3、用户注册功能(register.php):
<?php require_once 'config.php'; if ($_SERVER["REQUEST_METHOD"] == "POST") { $username = $_POST["username"]; $password = $_POST["password"]; $email = $_POST["email"]; $hashed_password = password_hash($password, PASSWORD_DEFAULT); $sql = "INSERT INTO users (username, password, email, role) VALUES ('$username', '$hashed_password', '$email', 'user')"; if ($conn>query($sql) === TRUE) { echo "注册成功!"; } else { echo "Error: " . $sql . "<br>" . $conn>error; } } ?>
4、用户登录功能(login.php):
<?php require_once 'config.php'; if ($_SERVER["REQUEST_METHOD"] == "POST") { $username = $_POST["username"]; $password = $_POST["password"]; $sql = "SELECT * FROM users WHERE username = '$username'"; $result = $conn>query($sql); if ($result>num_rows > 0) { $row = $result>fetch_assoc(); if (password_verify($password, $row["password"])) { echo "登录成功!"; } else { echo "密码错误!"; } } else { echo "用户名不存在!"; } } ?>
5、用户信息管理(profile.php):
<?php require_once 'config.php'; if ($_SERVER["REQUEST_METHOD"] == "POST") { $id = $_POST["id"]; $email = $_POST["email"]; $sql = "UPDATE users SET email = '$email' WHERE id = '$id'"; if ($conn>query($sql) === TRUE) { echo "更新成功!"; } else { echo "Error: " . $sql . "<br>" . $conn>error; } } ?>
6、权限管理(permission.php):
<?php require_once 'config.php'; if ($_SERVER["REQUEST_METHOD"] == "POST") { $id = $_POST["id"]; $role = $_POST["role"]; $sql = "UPDATE users SET role = '$role' WHERE id = '$id'"; if ($conn>query($sql) === TRUE) { echo "更新成功!"; } else { echo "Error: " . $sql . "<br>" . $conn>error; } } ?>
代码仅供参考,实际项目中还需要考虑更多的安全性和功能性问题。
