Laravel 5.x Multilanguage and localization module

Note: This package use by default use language ISO 639-1 two-letter codes for locale: https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes

The idea for this package is based on: Laravel-Translatable Upgrading Laravel's localization module Laravel 5 Translation Manager

• This is a Laravel package for translatable models.
• Read all translation files and save them in the database.
• Url modifier for local prefix. Examples: login/ => /it/login . / => /it

Installation

Require this package in your composer.json and run composer update (or run composer require simexis/multi-language directly):

simexis/multi-language

After updating composer, add the ServiceProvider to the providers array in config/app.php

'providers' => [
    Simexis\MultiLanguage\MultiLanguageServiceProvider::class,
]

You need to run the publish and migration.

$ php artisan vendor:publish
$ php artisan migrate

Routes are added in the ServiceProvider. You can set the group parameters for the routes in the configuration. You can change the prefix or filter/middleware for the routes. If you want full customisation, you can extend the ServiceProvider and override the map() function.

This example will make the translation manager available at http://yourdomain.com/multilanguage

Usage

Set current locale.

App::setLocale('ru');

Thene package work with ru locale.

Usage translation part

Web interface

When you have imported your translation (via buttons or command), you can view them in the webinterface (on the url you defined the with the controller). You can click on a translation and an edit field will popup. Just click save and it is saved :) When a translation is not yet created in a different locale, you can also just edit it to create it.

Using the buttons on the webinterface, you can append, replace, truncate and clear the translations.

You can also use the commands below.

Import command

The import command will search through resources/lang and load all strings in the database, so you can easily manage them.

$ php artisan translator:append

Note: By default, only new strings are added. Translations already in the DB are kept the same. If you want to replace all values with the ones from the files, use replace command: php artisan translator:replace

Truncate (delete) all transaltions from Database.

$ php artisan translator:truncate

Clear non existings translations.

$ php artisan translator:clear

Usage Url modifier for local prefix

For transform link from http://yourdomain.com/page to http://yourdomain.com/en/page, just use route or url functions. Example url('page') display http://yourdomain.com/en/page where en is App::getLocale()

Usage translatable models

Demo

Getting translated attributes

  $greece = Country::where('code', 'gr')->first();
  echo $greece->translate('en')->name; // Greece
  
  App::setLocale('en');
  echo $greece->name;     // Greece

  App::setLocale('de');
  echo $greece->name;     // Griechenland

Saving translated attributes

  $greece = Country::where('code', 'gr')->first();
  echo $greece->translate('en')->name; // Greece
  
  $greece->translate('en')->name = 'abc';
  $greece->save();
  
  $greece = Country::where('code', 'gr')->first();
  echo $greece->translate('en')->name; // abc

Filling multiple translations

  $data = [
    'code' => 'gr',
    'en'  => ['name' => 'Greece'],
    'fr'  => ['name' => 'Grece'],
  ];

  $greece = Country::create($data);
  
  echo $greece->translate('fr')->name; // Grece

Step 1: Migrations

In this example, we want to translate the model Country. We will need an extra table country_translations:

Schema::create('countries', function (Blueprint $table) {
	$table->increments('id');
	$table->string('code');
	$table->timestamps();
});
Schema::create('country_translations', function (Blueprint $table) {
	$table->increments('id');
	$table->integer('country_id')->unsigned();
	$table->string('name');
	$table->char(config('multilanguage.locale_key'), 2)->index('idx_locale');

	$table->unique(['country_id',config('multilanguage.locale_key')]);
	$table->foreign('country_id')->references('id')->on('countries')->onDelete('cascade');
	$table->foreign(config('multilanguage.locale_key'))
		->references(config('multilanguage.locale_key'))
		->on('languages')->onDelete('cascade')->onUpdate('cascade');
});

Step 2: Models

1. The translatable model Country should use the trait Simexis\MultiLanguage\Traits\Translatable.
2. The convention for the translation model is CountryTranslation.

// models/Country.php
class Country extends Model
{

    use \Simexis\MultiLanguage\Traits\Translatable;
    
    public $translatedAttributes = ['name'];
    protected $fillable = ['code', 'name'];
	
    /**
     * The database table used by the model.
     *
     * @var string
     */
    protected $table = 'countries';
}

// models/CountryTranslation.php
use Illuminate\Database\Eloquent\Model;

class CountryTranslation extends Model
{

    public $timestamps = false;
    protected $fillable = ['name'];
	
    /**
     * The database table used by the model.
     *
     * @var string
     */
    protected $table = 'country_translations';
}

The array $translatedAttributes contains the names of the fields being translated in the "Translation" model.

Configuration

The translation model

The convention used to define the class of the translation model is to append the keyword Translation.

So if your model is \MyApp\Models\Country, the default translation would be \MyApp\Models\CountryTranslation.

To use a custom class as translation model, define the translation class (including the namespace) as parameter. For example:

<?php 

namespace App\Models;

class Country extends Model
{

    use \Simexis\MultiLanguage\Traits\Translatable;
    
    public $translatedAttributes = ['name'];
    protected $fillable = ['code', 'name'];
	
    /**
     * The database table used by the model.
     *
     * @var string
     */
    protected $table = 'countries';

	//convention for the translation model is `CountryTranslation`.
    public $translationModel = 'MyApp\Models\CountryAwesomeTranslation';
}
