Role hierarchies (Admin → Super Admin)

From Admins to Super Admins: The Ultimate Handbook for WordPress User Roles and Network Management

Here’s a comprehensive dive into WordPress user roles, capabilities, and related topics, synthesized from the search results and organized for clarity:

1. Core Concepts: Roles vs. Capabilities

• Roles: Predefined sets of permissions (e.g., Administrator, Editor) that determine what users can do on a site. WordPress has six default roles, each with decreasing capabilities 25.

• Capabilities: Specific actions tied to roles, such as publish_posts or install_plugins. There are 70+ core capabilities, including special cases like unfiltered_upload (requires code activation).

• Hierarchy: Roles are not hierarchical, but capabilities are cumulative. For example, Editors inherit Author capabilities but have additional permissions.

2. Super Admin vs. Administrator: Key Differences

• Network-wide plugin/theme management

• Assign Super Admin/Admin roles | – Install themes/plugins

• Edit code/files

• Delete users | – Manage content on their site

• Cannot modify network settings |
  | Use Cases | Ideal for IT teams managing multisite networks (e.g., universities, franchises) | Site owners needing full control | Department heads in a multisite network.

3. Multisite Management Essentials

• Setup: Super Admin is created automatically in WordPress Multisite installations. Only they can access the Network Admin Dashboard to manage sites, themes, and users.

• Security Risks:

  • Limit Super Admins to trusted users (e.g., developers).

  • Use plugins like WP Activity Log to track network-wide changes.

• Customization:

  • Use add_role() or plugins like User Role Editor to create network-specific roles (e.g., “Network Content Moderator”).

4. Customizing Roles & Capabilities

• Plugins:

  • Members: Edit existing roles (e.g., remove delete_posts from Authors).

  • User Role Editor: Create custom roles (e.g., “SEO Manager” with access to Yoast SEO settings).

• Code Methods:

  • Add capabilities:

    php

    Copy

    Download

    $role = get_role('editor');  
    $role->add_cap('edit_theme_options');

  • Remove roles: remove_role('contributor');.

• Special Capabilities:

  • unfiltered_upload: Allows uploading restricted file types (e.g., SVG). Enable via define('ALLOW_UNFILTERED_UPLOADS', true); in wp-config.php.

5. Security Best Practices

• Principle of Least Privilege: Assign the lowest necessary role (e.g., use Contributors for draft submissions).

• Audit Logs: Tools like WP Activity Log monitor user actions (e.g., plugin installations, role changes).

• Two-Factor Authentication (2FA): Enforce for Administrators/Super Admins using plugins like Wordfence.

• Username Security: Avoid default “admin” usernames; use strong passwords.

6. Workflow Optimization Examples

1. Content Teams:

   • Editors approve Contributor drafts and manage categories.

   • Authors publish their own posts but cannot delete others’ content.

2. E-Commerce:

   • WooCommerce adds Shop Manager (manage orders) and Customer roles.

3. Membership Sites:

   • Use Subscribers with plugins like MemberPress to restrict content.

7. Advanced Topics

• Meta Capabilities: Dynamically granted based on context (e.g., edit_post Checks if the user owns the post.

• Gutenberg Reusable Blocks: New capabilities like create_reusable_blocks Allow editors to manage block templates.

• Multisite-Only Permissions:

  • manage_network (Super Admin)

  • upload_plugins (disabled for Multisite Admins).

8. Troubleshooting Common Issues

• Locked Out of Admin: Use PHPMyAdmin to reset user roles via the wp_usermeta table.

• Plugin Conflicts: Deactivate role-editing plugins if custom roles disappear 9.

• Sanitized HTML in Posts: Super Admins bypass sanitization; use unfiltered_html capability cautiously.

9. Recommended Plugins.

1. User Role Editor: Granular role customization.

2. Members: Create roles with drag-and-drop capabilities.

3. WP Activity Log: Track user actions.

4. Advanced Access Manager: Restrict content by role.

10. Future-Proofing Your Roles Strategy

• Audit Quarterly: Remove unused roles and update permissions as workflows evolve.

• Backup Roles: Use plugins like BackupBuddy to save role configurations.

• Stay Updated: Follow WordPress Core changes (e.g., Gutenberg-related capabilities) 511.
