README

Visual highlighting of pages in the TYPO3 backend page tree where the current user has content editing permissions.

Features

• Visual Feedback: Highlights pages with a customizable background color where the user has content editing rights
• Permission-Aware: Only shows highlights based on actual user permissions
• Admin-Optimized: Skips highlighting for admin users (who have all permissions anyway)
• Configurable: Customize the highlight color through extension configuration
• Lightweight: Minimal performance impact using TYPO3's event system

Why This Extension?

In large TYPO3 installations with complex permission structures, editors often struggle to identify which pages they can actually edit. This extension provides instant visual feedback in the page tree, making it immediately clear where users have content editing permissions.

Installation

Via Composer (recommended)

composer require ithilgers/pagetree-permissions-highlight

Activation

After installation, activate the extension in the Extension Manager or via CLI:

vendor/bin/typo3 extension:setup

Configuration

The extension can be configured in the Extension Configuration:

1. Go to Admin Tools > Settings > Extension Configuration
2. Select pagetree_permissions_highlight
3. Configure the following options:

Example Configuration

// config/system/settings.php
'EXTENSIONS' => [
    'pagetree_permissions_highlight' => [
        'highlightColor' => 'rgba(255, 215, 0, 0.15)', // Golden highlight
    ],
],

Usage

Once installed and activated, the extension works automatically:

1. Log in to the TYPO3 backend as a non-admin user
2. Open the page tree
3. Pages where you have content editing permissions are highlighted with the configured color
4. Admin users see no highlighting (as they have permissions everywhere)

Technical Details

Requirements

• TYPO3 12.4 or higher
• PHP 8.1 or higher

How It Works

The extension uses TYPO3's PSR-14 event system:

• Listens to AfterPageTreeItemsPreparedEvent
• Checks each page for Permission::CONTENT_EDIT rights
• Applies background color to permitted pages
• Skips processing for admin users
