How to implement website user rights management through PHP and Typecho

In a website, user rights management is a very important function. By properly setting user permissions, users' access to and operations on different functions and content can be effectively controlled. In this article, we will introduce how to implement website user rights management through PHP and Typecho, and provide code examples.

1. Create a user role table

First, we need to create a user role table to manage the permissions of different roles. Create a table named typecho_user_roles in the Typecho database, containing the following fields: id (role ID), name (role name), slug (English abbreviation of the character).

Code example:

CREATE TABLE `typecho_user_roles` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL,
  `slug` varchar(255) NOT NULL,
  PRIMARY KEY (`id`)
)

2. Create a user role association table

Next, we need to create a user role association table to associate users with roles. Create a table named typecho_user_role_relations in the Typecho database, containing the following fields: user_id (user ID), role_id (role ID).

Code example:

CREATE TABLE `typecho_user_role_relations` (
  `user_id` int(11) NOT NULL,
  `role_id` int(11) NOT NULL,
  PRIMARY KEY (`user_id`,`role_id`)
)

3. Create a permission table

Then, we need to create a permission table to manage different permissions for different roles. Create a table named typecho_user_permissions in the Typecho database, containing the following fields: id (permission ID), name (permission name), slug (English abbreviation for permission).

Code example:

CREATE TABLE `typecho_user_permissions` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL,
  `slug` varchar(255) NOT NULL,
  PRIMARY KEY (`id`)
)

4. Create a role permission association table

Next, we need to create a role permission association table to associate roles and permissions. Create a table named typecho_role_permission_relations in the Typecho database, containing the following fields: role_id (role ID), permission_id (permission ID).

Code example:

CREATE TABLE `typecho_role_permission_relations` (
  `role_id` int(11) NOT NULL,
  `permission_id` int(11) NOT NULL,
  PRIMARY KEY (`role_id`,`permission_id`)
)

5. Implement user rights management

In Typecho’s user registration, login, permission verification and other related operations, we can implement it through PHP code User rights management. The following is a sample code:

// 用户注册时，默认为普通用户角色
public function actionRegister()
{
    // 注册逻辑...
    
    // 将用户角色关联到普通用户角色
    $userRole = $this->select()->from('table.user_roles')->where('slug = ?', 'normal')->rows();
    $this->insert('table.user_role_relations')->rows(['user_id' => $userId, 'role_id' => $userRole['id']])->query();
}

// 用户登录时，验证用户权限
public function actionLogin()
{
    // 登录逻辑...

    // 查询用户角色和相关权限
    $user = // 查询用户信息...
    $roles = $this->select()->from('table.user_roles')->join('table.user_role_relations', 'table.user_roles.id = table.user_role_relations.role_id')->where('table.user_role_relations.user_id = ?', $userId)->rows();
    $permissions = $this->select()->from('table.user_permissions')->join('table.role_permission_relations', 'table.user_permissions.id = table.user_role_relations.permission_id')->where('table.role_permission_relations.role_id IN ?', $roles)->rows();

    // 验证用户权限
    if (in_array('create_post', $permissions)) {
        // 用户有创建文章的权限
    } else {
        // 用户没有创建文章的权限
    }
}

Through the above code example, we can implement the website user rights management function based on roles and permissions. By creating user role tables, user role association tables, permission tables and role permission association tables, we can define different roles and permissions and associate users with roles and permissions. By verifying user roles and permissions in relevant operations, permission control for different users can be achieved.

Summary:

Through PHP and Typecho, we can implement website user rights management functions. Properly setting user roles and permissions can effectively control users' access to and operations on different functions and content. By creating relevant data tables and writing corresponding code logic, we can implement user rights management functions based on roles and permissions. The above is a simple implementation example, and developers can expand and optimize it according to actual needs.
