Select language

This module contains some function to set language for your yii2 application.

1. To change language, add the config below into your web config (config/web.php or frontend/config/main.php)

  return [
      'bootstrap' => [
          [
              'class' => 'umbalaconmeogia\i18nui\components\LanguageSelector',
              'supportedLanguages' => ['vi', 'ja'],
          ],
          // Other stuffs.
      ],
  ],

1. To add link to change config, use /i18nui/default/set-language. For example, add to menu

  $languages = [
      'vi' => 'Tiếng Việt',
      'ja' => '日本語',
  ];
  $callbackUrl = Yii::$app->request->getAbsoluteUrl();

  foreach ($languages as $langCode => $langName) {
      $menuItems[] = [
          'label' => $langName,
          'url' => Url::to(['/i18nui/default/set-language',
          'language' => $langCode, 'callbackUrl' => $callbackUrl]),
      ];
  }

Import message data from CSV

To import i18n data from CSV, run command

php yii i18nui/import/csv i18n.csv

while i18n.csv is created as bellow (the first row is the header, with the first key is category, the second key is message, follow by language codes)

Add language related menu items

Add menu items as sub-menu

Add language related menu as sub menu items on menu bar.

    $languageMenuItems = [];
    $languageMenuItems[] = ['label' => Yii::t('app', 'Translation manager'), 'url' => ['/i18nui']];

    $languages = [
        'vi' => 'Tiếng Việt',
        'ja' => '日本語',
    ];
    $callbackUrl = Yii::$app->request->getAbsoluteUrl();

    foreach ($languages as $langCode => $langName) {
        $languageMenuItems[] = ['label' => $langName, 'url' => Url::to(['/i18nui/default/set-language', 'language' => $langCode, 'callbackUrl' => $callbackUrl])];
    }

    $menuItems[] = [
        'label' => Yii::t('app', 'Language'),
        'items' => $languageMenuItems,
    ];

Add menu items as sub-sub-menu

Add language related menu as an item of sub menu on menu bar.

Use kartik-v/yii2-nav-x to display sub-sub-menu easily.

    $languageMenuItems = [];
    $languageMenuItems[] = ['label' => Yii::t('app', 'Translation manager'), 'url' => ['/i18nui']];

    $languages = [
        'vi' => 'Tiếng Việt',
        'ja' => '日本語',
    ];
    $callbackUrl = Yii::$app->request->getAbsoluteUrl();

    foreach ($languages as $langCode => $langName) {
        $languageMenuItems[] = ['label' => $langName, 'url' => Url::to(['/i18nui/default/set-language', 'language' => $langCode, 'callbackUrl' => $callbackUrl])];
    }
    $adminMenuItems[] = [
        'label' => Yii::t('app', 'Language'),
        'items' => $languageMenuItems,
    ];

    $menuItems[] = [
        'label' => Yii::t('app', 'Admin'),
        'items' => $adminMenuItems,
    ];
    // Other stuffs

    echo NavX::widget([
        // 'options' => ['class' => 'ml-3 navbar-nav navbar-left'],
        'options' => ['class' => 'navbar-nav navbar-right'],
        'encodeLabels' => FALSE,
        'items' => $menuItems,
    ]);

Use another Message, SourceMessage classes

If you want to use your own Message, SourceMessage classes, define them and declared in configuration of i18nui.

For example.

Config

    'modules' => [
        'i18nui' => [
            'class' => 'umbalaconmeogia\i18nui\Module',
            'languages' => ['ja', 'vi'], // Any languages that you want to use
            'modelMessageClass' => 'frontend\models\NewMessage',
        ],
    ],

Class frontent\models\NewMessage

namespace frontend\models;
class NewMessage extends \umbalaconmeogia\i18nui\models\Message
{
    public function afterSave($insert, $changedAttributes)
    {
        parent::afterSave($insert, $changedAttributes);

        \Yii::trace('New afterSave', __METHOD__);
    }
}
