README

A Twill CMS capsule for managing Laravel translations directly from the admin panel. Built on top of LaravelTranslationHandler.

Twill compatibility: Currently supports Twill 3 (Laravel 11, PHP 8.2+). Twill 2 support is available in the v0.x releases.

Features

Translation key management — Browse and edit all translation keys and their per-locale values from a clean Twill module interface.
Group-based organization — Translations are automatically grouped by prefix (e.g. messages, messages.validation). Groups are created automatically on import and provide a focused editing view via Twill repeaters.
Multi-locale support — Edit translations for all configured locales side by side. Individual locale values can be marked active or inactive.
Import / Export — Sync translations between the database and CSV files:
- Import from PHP files to populate the database
- Export all translations to CSV or upload a CSV to import
- Export a single group as CSV directly from its edit page
Automatic group syncing — When translations are imported, the DatabaseHandler automatically creates all intermediate group levels (e.g. importing messages.validation.required creates both messages and messages.validation groups).
Auto-sync to PHP files — Saving a translation key or a group automatically exports the affected PHP language file, keeping the filesystem always in sync with the database.

Requirements

PHP 8.2 or 8.3
Laravel 11
Twill 3.x
brunoscode/laravel-translation-handler ^2.0

Installation

composer require brunoscode/twill-translation-handler

Run the migrations:

php artisan migrate

Publish the config file:

php artisan vendor:publish --tag="twill-translation-handler-config"

Optionally publish the views to customise them:

php artisan vendor:publish --tag="twill-translation-handler-views"

Navigation

The package registers a Translations entry in the Twill admin sidebar automatically — no extra configuration needed. It provides three sub-pages:

Translations — browse and edit individual translation keys
Groups — edit translations grouped by prefix
Import / Export — sync translations via CSV

Controlling the position in the sidebar

The package always overwrites the translations key in twill-navigation at boot with its own structure. To control where it appears in the sidebar, add an empty placeholder for translations in your app's navigation config — PHP arrays preserve the insertion order of existing keys:

// config/twill-navigation.php

return [
    'dashboard' => [
        'title' => 'Dashboard',
        'route' => 'admin.dashboard',
    ],

    // Placeholder — position is preserved, structure is filled in by the package
    'translations' => [],

    'pages' => [
        'title' => 'Pages',
        'route' => 'admin.pages.index',
    ],

    // ...
];

Configuration

// config/translation-handler.php

return [
    'keyDelimiter' => '.',          // Separator used in nested translation keys

    'fileNames' => ['messages'],    // PHP file names to sync (without .php extension)
    'locales'   => ['en', 'it'],    // Supported locales

    // Default import/export direction
    'defaultImportFrom' => TranslationOptions::PHP,
    'defaultImportTo'   => TranslationOptions::DB,
    'defaultExportFrom' => TranslationOptions::DB,
    'defaultExportTo'   => TranslationOptions::PHP,

    'phpPath'      => lang_path(),          // Path to PHP language files
    'csvDelimiter' => ';',                  // CSV column delimiter
    'csvFileName'  => 'translations',       // Default CSV file name
    'csvPath'      => storage_path('lang'), // Directory for CSV files
    'jsonPath'     => lang_path(),          // Path to JSON language files
];

See LaravelTranslationHandler for the full list of configuration options.

Usage

Once installed, a Translations section will appear in the Twill admin navigation with three pages:

Keys

Lists all translation keys stored in the database. Each key can be opened to edit its translated value for every configured locale. Translation keys are managed exclusively through import — manual creation is intentionally disabled to keep the database in sync with source files.

Groups

Lists all translation groups, auto-generated from the key prefixes. Opening a group shows all matching keys in a repeater, allowing batch editing of every locale's value from a single form.

Import / Export

A tools page with actions to sync translations:

Action	Description
Import from CSV	Uploads a CSV file, imports all translations into the database, and writes the PHP language files
Export to CSV	Downloads all database translations as a CSV file

Per-group CSV export is also available directly from each group's edit page.

CSV import rules

The file does not need to contain all keys — only the keys present in the file will be updated.
All locale columns must be present in the file header.
Empty values will overwrite the existing translation with an empty string.

PHP language files are kept in sync automatically: every import (CSV via the tools page or per-group) writes the affected PHP files immediately after updating the database. Saving a single key or group from the edit form also triggers the same export.

Deployment

The database is the source of truth for translation values. PHP language files are used only to carry new keys and new locales between environments.

A typical deploy script:

php artisan migrate

# Add new keys and locales from PHP files to the DB, without overwriting existing DB values
php artisan translation-handler php db

# Overwrite PHP files with the authoritative DB values
php artisan translation-handler db php --force

The first command (without --force) inserts only keys and locale entries that do not yet exist in the DB — existing values are left untouched. The second command rewrites the PHP files so they always reflect the DB state.

First deploy / fresh environment: if the DB is empty, seed it from the PHP files:
php artisan translation-handler php db --force

Syncing translations from production

When content editors have updated translations directly in production or staging, you can pull those changes back into the repository:

Download the CSV from the production admin panel via Translations → Import / Export → Export to CSV.
Copy the file into your project (e.g. storage/lang/translations.csv) and import it to regenerate the PHP files:

php artisan translation-handler csv php --force

Commit the updated PHP files and push:

git add lang/
git commit -m "chore: sync translations from production"
git push

The next deploy will import the updated PHP files into any environment whose DB does not yet have those values.

Database Structure

Table	Description
`translation_keys`	Translation keys (`key`, `published`)
`translation_values`	Per-locale values (`locale`, `value`, `active`)
`translation_groups`	Group prefixes (`prefix`, `published`)
