WordPress' user permission system is relatively intuitive and flexible, allowing administrators to assign different permission levels to users as needed. Whether you are managing a simple blog or a complex multi-user website, understanding and effectively managing user permissions is critical. In this article, we'll take a closer look at the various user roles and their permissions in WordPress, and provide some practical advice on managing and customizing user permissions.

WordPress User Roles and Permissions

1. Super Admin

The Super Administrator role usually exists only in multi-site networks (Multisite). The Super Administrator has the highest level of authority in the network and is able to manage all sites across the network. Specific permissions include:

• Manage all sites in the network, including creating, editing, and deleting sites.
• Manage all users on the network, including other super administrators.
• Has permissions for all other user roles in the site.

2. Administrator

The Administrator is the most privileged user role on a single site. Administrators can manage all aspects of the site, including:

• Install, activate, update and remove themes and plugins.
• Add, edit, and delete users, and assign permissions to users.
• Change website settings and options.
• Publish, edit and manage articles and pages.
• Manage all content on the site, including media, comments, etc.

3. Editor

Editors can manage the content of the site, but do not have permissions to manage site settings or to install and remove themes and plugins. Specific permissions include:

• Publish, edit and manage articles and pages.
• Manage other authors' posts and pages.
• Management Comment.
• Manage the site's media library.

Authors can create and manage their own content, but cannot manage other users' content or site settings. Specific permissions include:

• Write and edit your own articles.
• Publish and manage your own articles.
• Upload and manage your own media files.

5. Contributor

Contributors can write and edit their own articles, but not publish them. Specific permissions include:

• Write and edit your own articles.
• Submit articles for review.
• Unable to upload files to the media library.
• Need to have their articles reviewed and published by other users (e.g. editors or administrators).

6. Subscriber

Subscriber permissions are minimal and are typically used to receive website notifications or email subscriptions. Specific permissions include:

• Manage your own profile.
• Unable to post, edit articles or pages.
• It is not possible to change site settings or install or remove themes and plug-ins.

Customize user roles and permissions

In addition to these pre-defined user roles, WordPress also allows for the creation and management of custom user roles via plugins or custom code to suit specific permission needs. Here are two ways to do this:

Customizing user roles with plug-ins

1. User Role Editor plug-in (software component) User Role Editor is a powerful plugin that helps you easily create and manage custom user roles. After installing and activating the plugin, you can create and manage custom user roles in the "subscribers"Under the menu, find "User Role Editor"Options.
   • Add New Role: click "Add Role", enter the role name and description, and then set the permissions for the role.
   • Edit existing roles: Select the role you want to edit, check or uncheck the appropriate permissions, and then save the changes.

2. Members Plug-in The Members plugin is also a powerful tool that provides additional user rights management features. You can use it to create new roles, edit existing roles, set content access rights, and more.

Creating user roles through custom code

If you are familiar with programming, you can use custom code to create and manage user roles in WordPress. Below is a sample code showing how to create a custom role:

function my_custom_role() {
    add_role('custom_role', 'Custom Role', array(
        'read' => true,
        'edit_posts' => true,
        'delete_posts' => false, .
    ));
}
add_action('init', 'my_custom_role');

This code will create a file in WordPress called "Custom Role" role with permissions to read and edit posts, but no permissions to delete posts. Permissions can be added or removed as needed.

Manage user roles and permissions

Managing user roles and permissions in WordPress is very simple. Manage user roles and permissions in WordPress by "subscribers" menu, you can add new users, edit user information, and assign roles to users. Here are some useful tips for managing user roles:

utilizationHooksand APIs to control user permissions

WordPress provides hooks and APIs that allow developers to programmatically control user permissions in a more granular way. Below are some commonly used hooks and functions:

add_cap cap (a poem) remove_cap

These two functions can add or remove permissions for specific roles. Example:

function add_custom_capabilities() {
    $role = get_role('editor');
    $role->add_cap('edit_theme_options');
}
add_action('admin_init', 'add_custom_capabilities');

current_user_can

This function is used to check if the current user has specific privileges. Example:

if (current_user_can('edit_posts')) {
    // The current user can edit posts
}
