Usage

Setting translations to the entity

To set translations to the entity

$post = new Post();

// title attribute translation for default application language
$post->title = 'Post title';

// body attribute translation for default application language
$post->body = 'Post body';

// title attribute translation for German
$post->translate('de-DE')->title = 'Post titel';

// body attribute translation for German
$post->translate('de-DE')->body = 'Post inhalt';

// title attribute translation for Russian
$post->translate('ru-RU')->title = 'Заголовок поста';

// body attribute translation for Russian
$post->translate('ru-RU')->body = 'Тело поста';

// save post and its translations
$post->save();

Getting translations from the entity

To get translations from the entity

$posts = Post::find()->with('translations')->all();

foreach ($posts as $post) {
    // title attribute translation for default application language
    $title = $post->title;

    // body attribute translation for default application language
    $body = $post->body;

    // title attribute translation for German
    $germanTitle = $post->translate('de-DE')->title;

    // body attribute translation for German
    $germanBody = $post->translate('de-DE')->body;

    // title attribute translation for Russian
    $russianTitle = $post->translate('ru-RU')->title;

    // body attribute translation for Russian
    $russianBody = $post->translate('ru-RU')->body;
}

Checking for translations in the entity

To check translations in the entity

$post = Post::findOne(1);

// checking for default application language translation
$result = $post->hasTranslation();

// checking for German translation
$result = $post->hasTranslation('de-DE');

// checking for Russian translation
$result = $post->hasTranslation('ru-RU');

Advanced usage

Collecting tabular input

Example of controller actions

class PostController extends Controller
{
    public function actionCreate()
    {
        $model = new Post();

        foreach (Yii::$app->request->post('PostTranslation', []) as $language => $data) {
            foreach ($data as $attribute => $translation) {
                $model->translate($language)->$attribute = $translation;
            }
        }

        //...
    }

    public function actionUpdate($id)
    {
        $model = Post::find()->with('translations')->where(['id' => $id])->one();

        if ($model === null) {
            throw new NotFoundHttpException('The requested page does not exist.');
        }

        foreach (Yii::$app->request->post('PostTranslation', []) as $language => $data) {
            foreach ($data as $attribute => $translation) {
                $model->translate($language)->$attribute = $translation;
            }
        }

        //...
    }
}

Example of view form

<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;

$form = ActiveForm::begin();

foreach (['en-US', 'de-DE', 'ru-RU'] as $language) {
    echo $form->field($model->translate($language), "[$language]title")->textInput();
    echo $form->field($model->translate($language), "[$language]body")->textarea();
}

//...

ActiveForm::end();

Language specific translation attribute labels

Example of model attribute labels

class PostTranslation extends \yii\db\ActiveRecord
{
    public function attributeLabels()
    {
        switch ($this->language) {
            case 'de-DE':
                return [
                    'title' => 'Titel',
                    'body' => 'Inhalt',
                ];
            case 'ru-RU':
                return [
                    'title' => 'Заголовок',
                    'body' => 'Тело',
                ];
            default:
                return [
                    'title' => 'Title',
                    'body' => 'Body',
                ];
        }
    }
}
