Laravel content translation

This package makes properties of your models translatable. For example when you have a Country model then you can make the country name translatable.

Todo

• Add user interface to add translations.
• Add tests
• Method to disable the "static translations".

Installation

This package can be installed through Composer.

composer require jvdlaar/laravel-content-translation

You must install this service provider.

// config/app.php
'providers' => [
    ...
    JvdLaar\ContentTranslation\ContentTranslationServiceProvider::class,
    ...
];

This package also comes with a facade, which provides an easy way to call the the class.

// config/app.php
'aliases' => [
    ...
    'ContentTranslation' => JvdLaar\ContentTranslation\ContentTranslationFacade::class,
    ...
];

You can publish the config file of this package with this command:

php artisan vendor:publish --provider="JvdLaar\ContentTranslation\ContentTranslationServiceProvider"

The following config file will be published in config/content-translation.php

return [
  'fallback_language' => 'en',

  'country' => [
    'class' => \App\Models\Country::class,
    'label_property' => 'name',
    'properties' => [
      'name' => ['required' => TRUE],
      'nationality' => ['required' => TRUE],
    ],
  ],

  'page' => [
    'class' => \App\Models\Test::class,
    'label_property' => 'title',
    'properties' => [
      'title' => ['required' => TRUE],
      'body' => ['nl2br' => TRUE],
    ],
  ],
];

The array key is they key with which the translations are stored in the database, "class" refers to the model class. "label_property" is used to determine the translatable label of this model. E.g. the country name in the country model. "properties" is an array with the translatable properties and whether they are required and their output needs to be nl2br.

Usage

After installation and configuration you need to make models translatable by implementing the TranslatableContract. The HasTranslatables trait helps with this.

Example model

namespace App\Models;

use App\Base\Model;
use App\Contracts\TranslatableContract;
use App\Models\Traits\HasTranslatables;

class Country extends Model implements TranslatableContract {

  use HasTranslatables;

  protected $table = 'countries';
  protected $fillable = ['code', 'admin_name'];
  public $timestamps = FALSE;
  public $users = FALSE;



  /**
   * ATTRIBUTES
   */

  /**
   * Getter for 'name'.
   */
  public function getNameAttribute() {
    return $this->displayTranslation('name', TRUE);
  }

  /**
   * Getter for 'nationality'.
   */
  public function getNationalityAttribute() {
    return $this->displayTranslation('nationality', TRUE);
  }

  /**
   * Return an default for a property in this content.
   */
  protected function getTranslationDefault($property) {
    return $this->admin_name;
  }

}

In above example $country->name and $country->nationality are translated. When there is no translation in the database the admin_name property is used as fallback. The 2nd parameter of the function displayTranslation says that there is a default that should be used. The 3rd parameter is the locale of the translation, by default the current app locale will be used. 4th parameter determines that a fallback language should be used, this fallback language is set in the config.

Eager load translations for multiple models.

Country::eagerLoadTranslations([1, 2, 3], 'nl');
dump(Country::find(1)->name);

In above example 3 countries are eager loaded. So loading the model later and requesting a translation doesn't need an additional query.

Saving translations

You can add a translation to the database by using the facade:

\ContentTranslation::saveTranslation('country', $country->id, 'name', 'nl', 'Nederland');

Or by using a method on the model:

$country->saveTranslation('nl', ['name' => 'Nederland', 'nationality' => 'Nederlander']);
