WordPress角色权限系统概述
WordPress角色权限系统是CMS的核心安全机制，它通过精细的权限控制确保网站内容的安全管理。与其他CMS系统类似，WordPress采用角色(Role)和权限(Capability)的双层验证体系。
WordPress Role Permission System Overview
The WordPress role permission system is the core security mechanism of CMS, ensuring secure management of website content through fine-grained permission control. Similar to other CMS systems, WordPress adopts a dual-layer verification system of roles and capabilities.
默认用户角色包括：
- 管理员(Administrator) - 拥有全部管理权限
- 编辑(Editor) - 可管理所有文章内容
- 作者(Author) - 仅管理自己的文章
- 投稿者(Contributor) - 可撰写但不能发布文章
- 订阅者(Subscriber) - 仅基础浏览权限
Default User Roles Include:
- Administrator - Has all management permissions
- Editor - Can manage all article content
- Author - Only manages their own articles
- Contributor - Can write but cannot publish articles
- Subscriber - Only basic browsing permissions
权限控制与后台菜单
开发插件/主题时，常用以下函数添加管理菜单：
add_menu_page(page_title, menu_title, capability, handle);
add_submenu_page(parent, page_title, menu_title, capability, handle);
关键参数capability决定哪些用户可见该菜单。
Permission Control and Backend Menu
When developing plugins/themes, the following functions are commonly used to add management menus:
add_menu_page(page_title, menu_title, capability, handle);
add_submenu_page(parent, page_title, menu_title, capability, handle);
The key parameter capability determines which users can see the menu.
权限验证方法
使用current_user_can()验证用户权限：
if (current_user_can('edit_post', $post_id)) {
// 执行编辑操作
}
Permission Verification Methods
Use current_user_can() to verify user permissions:
if (current_user_can('edit_post', $post_id)) {
// Execute editing operations
}
自定义角色与权限
创建新角色：
add_role('photo_uploader', 'Photo Uploader', array('organize_gallery'));
为现有角色添加权限：
$role = get_role('author');
$role->add_cap('organize_gallery');
Custom Roles and Permissions
Create new roles:
add_role('photo_uploader', 'Photo Uploader', array('organize_gallery'));
Add permissions to existing roles:
$role = get_role('author');
$role->add_cap('organize_gallery');
高级权限管理类
WordPress提供三个核心类进行深度权限控制：
WP_Roles - 全局角色管理
WP_Role - 单个角色操作
WP_User - 用户级权限控制
Advanced Permission Management Classes
WordPress provides three core classes for deep permission control:
WP_Roles - Global role management
WP_Role - Single role operations
WP_User - User-level permission control
