PolyCMS Plugin Management

Plugin System Overview

Plugins extend PolyCMS functionality without modifying core code. Navigate to Blog > Plugins to manage all installed plugins.

Plugin Listing

The Plugins page displays all installed plugins with:

• Plugin name, version, and author
• Short description
• Active/Inactive status
• Activate/Deactivate toggle
• Settings link (if the plugin has a settings page)
• Grid and List view modes

Installing Plugins

ZIP Upload

1. Navigate to Blog > Plugins.
2. Click Upload Plugin.
3. Select a .zip file containing the plugin package.
4. PolyCMS validates, scans for security threats, and extracts the plugin to modules/polycms/plugins/.
5. After installation, click Activate to enable the plugin.

Manual Installation

Upload the plugin folder directly to modules/polycms/plugins/ via FTP.

Plugin Security

ZIP uploads undergo security scanning:

• Dangerous PHP function detection and stripping
• File extension validation
• Directory traversal prevention via polycms_validate_file_path

Bundled Plugins

PolyCMS ships with 7 production-ready plugins:

Plugin Settings

Active plugins that register settings pages display a Settings link in the plugin listing. Each plugin manages its own configuration independently via the blog_plugin_options database table.

Plugin Architecture

Each plugin resides in its own directory:

modules/polycms/plugins/
├── xml-sitemap/
│   ├── plugin.json        ← Plugin metadata
│   ├── xml-sitemap.php    ← Main plugin file
│   ├── language/          ← Translation files
│   └── assets/            ← CSS/JS assets
├── google-analytics/
└── maintenance-mode/

Plugins interact with PolyCMS core through the Hook & Filter system, registering actions and filters to extend functionality.
