README

A Kirby 5 CMS panel plugin that provides a safe, time-limited debug mode toggle with automatic expiry and git-safe flag file management.

License Kirby

Features

  • Flag-based debug control - Uses a .debug_enabled flag file instead of modifying config.php
  • Panel auto-debug - Automatically enables debug for panel when authorized users are logged in (prevents panel lockout)
  • Auto-expiry - Debug mode automatically disables after configured hours
  • Permission system - Restrict access by admin status, role name, or custom callback
  • Git-safe - Automatically adds flag file to .gitignore
  • Panel UI - Clean card-based interface with status indicator
  • Dark/Light mode - Fully responsive to Kirby panel theme (Kirby 5) and fallback for Kirby 4
  • Real-time status - Shows who enabled debug and when it expires

Why this exists

The built-in Kirby workarounds for toggling debug mode didn't fully fit my needs. So I built this for myself. It does exactly what I need and nothing more. If it fits yours too, feel free to use it.

Installation

Manual Installation

  1. Download and extract the plugin to site/plugins/debug-toggle/
  2. The plugin structure should be: 
    site/plugins/debug-toggle/
├── index.php
├── index.js
├── index.css
├── README.md
└── LICENSE

Composer Installation

composer require martino/kirby-debug-toggle

Configuration

⚠️ Required: Add the following to your site/config/config.php:

return [
    // REQUIRED: Debug mode controlled by flag file
    // Replace any existing 'debug' => true with this closure
    'debug' => (function() {
        $flag = __DIR__ . '/.debug_enabled';
        if (!file_exists($flag)) return false;
        $data = @json_decode(file_get_contents($flag), true);
        if (!$data || empty($data['expires_at'])) return false;
        return time() < $data['expires_at'];
    })(),
    
    // OPTIONAL: Plugin configuration (uses defaults if omitted)
    'Martino.debug-toggle.expiry-hours' => 4,  // Hours until auto-disable (default: 4)
    'Martino.debug-toggle.permission' => 'admin',  // Who can toggle (default: 'admin')
    'Martino.debug-toggle.panel-auto-debug' => true,  // Auto-enable debug for panel (default: true)
];

Important: The debug closure is required for the plugin to work. Without it, the panel UI will appear but debug mode won't actually activate when toggled.

Panel Auto-Debug: By default, debug mode is automatically enabled in the panel for authorized users (even when the toggle is OFF). This prevents panel corruption from hiding errors. You can disable this by setting 'Martino.debug-toggle.panel-auto-debug' => false.

Configuration Options

Martino.debug-toggle.expiry-hours

Type: int
Default: 4

Number of hours until debug mode automatically disables.

'Martino.debug-toggle.expiry-hours' => 8,  // 8 hours

Martino.debug-toggle.permission

Type: string|callable
Default: 'admin'

Controls who can access and toggle debug mode.

Options:

  1. 'admin' - Only users with admin status (uses isAdmin())

    'Martino.debug-toggle.permission' => 'admin',

  2. Role name - Only users with specific role

    'Martino.debug-toggle.permission' => 'editor',
'Martino.debug-toggle.permission' => 'developer',

  3. Custom callback - Custom permission logic

    'Martino.debug-toggle.permission' => function($user) {
    return in_array($user->email(), ['dev@example.com', 'admin@example.com']);
},

Martino.debug-toggle.panel-auto-debug

Type: bool
Default: true

Automatically enables debug mode in the panel for authorized users, even when the toggle is OFF.

Why this exists: If the panel breaks due to an error, you need debug mode to see what went wrong. With this enabled, authorized users always see panel errors, preventing you from being locked out.

'Martino.debug-toggle.panel-auto-debug' => true,  // Always show panel errors to authorized users
'Martino.debug-toggle.panel-auto-debug' => false, // Disable auto-debug (not recommended)

Behavior:

  • ✅ Frontend: Controlled by the toggle (manual)
  • ✅ Panel (authorized users): Always ON (auto-debug)
  • ✅ Panel (public/unauthorized): Controlled by the toggle

Usage

  1. Log in to the Kirby panel as an authorized user
  2. Click Debug in the sidebar menu
  3. Click Turn ON to enable debug mode
  4. Debug mode will automatically disable after the configured expiry time
  5. Click Turn OFF to manually disable debug mode

Panel Interface

The debug toggle interface displays:

  • Status - Current state (ON/OFF)
  • Enabled by - Email of user who enabled debug
  • Expires at - Timestamp when debug will auto-disable
  • Warning message - Reminder that errors are visible to all visitors
  • Status indicator - Visual dot (orange = active, gray = inactive)

How It Works

Flag File System

The plugin uses a flag file at site/config/.debug_enabled to control debug mode:

{
  "enabled_by": "admin@example.com",
  "enabled_at": 1712345678,
  "expires_at": 1712359678
}

Benefits:

  • No modification of config.php required
  • Git-safe (automatically added to .gitignore)
  • Automatic expiry prevents forgotten debug mode
  • Tracks who enabled debug and when

Security

  • All API routes require authentication and permission checks
  • Flag file is created with chmod 0600 (owner read/write only)
  • Expired flags are automatically deleted on next state check
  • Default state is OFF (no flag file = no debug)

API Routes

The plugin provides two API endpoints:

GET /api/debug-toggle/state

Returns current debug state and metadata.

Response:

{
  "debug": true,
  "enabled_by": "admin@example.com",
  "enabled_at": "2024-04-05 14:00",
  "expires_at": "2024-04-05 18:00",
  "expired": false
}

POST /api/debug-toggle/state

Toggles debug mode on or off.

Request:

{
  "enabled": true
}

Response: Same as GET endpoint

Requirements

  • Kirby 5.x
  • PHP 8.2+
  • Panel access with appropriate permissions

Troubleshooting

Debug toggle menu not visible

  • Verify you're logged in as an admin user (or user with configured permission)
  • Check that the plugin files are in site/plugins/debug-toggle/
  • Hard refresh the panel (Cmd+Shift+R / Ctrl+Shift+R)

Debug mode not working

  • Verify the debug config closure is added to config.php
  • Check file permissions on site/config/ directory
  • Ensure .debug_enabled file can be created/deleted

Permission denied errors

  • Verify your user has the required permission level
  • Check the Martino.debug-toggle.permission config option

  • debugFlagData() - Reads and decodes flag file
  • debugFlagExpired() - Checks if flag has expired
  • debugFlagActive() - Checks if debug is currently active
  • debugHasPermission() - Checks if current user has permission
  • ensureGitIgnore() - Adds flag file to .gitignore
