How to use PHP and Vue to develop permission management functions for warehouse management

Title: Using PHP and Vue to develop permission management functions for warehouse management

In modern enterprises, warehouse management is an important task. In order to improve work efficiency and management accuracy, many companies choose to use computer systems for warehouse management. Among them, the authority management function is an indispensable part of the warehouse management system. This article will introduce how to use PHP and Vue to develop the permission management function of warehouse management, and provide specific code examples.

1. Requirements for authority management functions

In the warehouse management system, the authority management functions mainly include the following aspects:

1. User management: realizing the user’s Registration, login and permission assignment.
2. Role management: Define the permissions owned by different roles and assign roles to users.
3. Permission management: Define various operations and resources in the system, and assign corresponding permissions to roles.
4. Permission verification: Perform permission verification in each module of the system to ensure that users can only access functions or resources for which they have permission.

2. Development environment preparation

In order to realize the permission management function, we need to prepare the following development environment:

1. PHP environment: PHP needs to be installed and configured A good web server such as Apache or Nginx.
2. MySQL database: Permission management requires the use of a database to save user, role and permission information.
3. Vue.js environment: Vue.js is a progressive framework for building user interfaces, and we will use it to implement front-end pages.

3. Back-end development

1. User management

First, we create a user table (users) to save user information, including User ID, username and password. You also need to create a user role table (user_roles) to save the information related to users and roles.

Sample code (PHP):

// 创建用户表
CREATE TABLE users (
  id INT AUTO_INCREMENT PRIMARY KEY,
  username VARCHAR(50) NOT NULL,
  password VARCHAR(255) NOT NULL
);

// 创建用户角色表
CREATE TABLE user_roles (
  user_id INT NOT NULL,
  role_id INT NOT NULL,
  PRIMARY KEY (user_id, role_id),
  FOREIGN KEY (user_id) REFERENCES users(id),
  FOREIGN KEY (role_id) REFERENCES roles(id)
);

2. Role management

Create a role table (roles) to save role information, including role ID and role name.

Sample code (PHP):

// 创建角色表
CREATE TABLE roles (
  id INT AUTO_INCREMENT PRIMARY KEY,
  name VARCHAR(50) NOT NULL
);

3. Permission management

Create a permission table (permissions) to save permission information, including permission ID and permissions name.

Sample code (PHP):

// 创建权限表
CREATE TABLE permissions (
  id INT AUTO_INCREMENT PRIMARY KEY,
  name VARCHAR(50) NOT NULL
);

Create a role permission table (role_permissions) to save the related information of roles and permissions.

Sample code (PHP):

// 创建角色权限表
CREATE TABLE role_permissions (
  role_id INT NOT NULL,
  permission_id INT NOT NULL,
  PRIMARY KEY (role_id, permission_id),
  FOREIGN KEY (role_id) REFERENCES roles(id),
  FOREIGN KEY (permission_id) REFERENCES permissions(id)
);

4. Permission verification

In the interface or function that requires permission verification, check the user's role and Permission information is verified. When a user requests a resource that requires permissions, we can perform the following verification on the backend:

Sample code (PHP):

// 检查用户是否具有某个权限
function checkPermission($userId, $permissionName) {
  // 查询用户的角色ID
  $roleId = "SELECT role_id FROM user_roles WHERE user_id = $userId";
  
  // 查询角色是否具有该权限
  $result = "SELECT * FROM role_permissions rp
    INNER JOIN permissions p ON rp.permission_id = p.id
    WHERE rp.role_id = $roleId AND p.name = $permissionName";

  // 若查询结果为空，则用户没有该权限
  if (empty($result)) {
    return false;
  } else {
    return true;
  }
}

4. Front-end development

In In Vue.js, we can use the features of componentization and routing to implement permission management on the front-end page. In each component that requires permission control, permission verification can be performed through routing guards.

Sample code (Vue.js):

// 路由守卫
router.beforeEach((to, from, next) => {
  // 获取用户的角色和权限信息
  let userRoles = getUserRoles();
  let userPermissions = getUserPermissions();
  
  // 进行权限验证
  if (hasPermission(userRoles, userPermissions, to.meta.permission)) {
    next();
  } else {
    next('/403'); // 没有权限，跳转到无权限页面
  }
});

// 判断用户是否具有某个权限
function hasPermission(userRoles, userPermissions, permissionName) {
  for (let i = 0; i < userRoles.length; i++) {
    for (let j = 0; j < userRoles[i].permissions.length; j++) {
      if (userRoles[i].permissions[j].name === permissionName) {
        return true;
      }
    }
  }
  return false;
}

5. Summary

By using PHP and Vue to develop the permission management function of warehouse management, we can realize user management and roles Management, permission management and permission verification functions. These functions can effectively control user access rights and improve the security and efficiency of warehouse management. Of course, the development process still needs to be adjusted and improved according to specific needs, but the above example code provides a basic implementation idea. I hope this article will be helpful to you when developing the permission management function of the warehouse management system.
