从另一家商店获取翻译

Question

I'm trying to programatically send a custom email from admin and I need to add some strings before sending the email. I would like to translate these strings based on a language selected. I used the code below but it does not work, the string stays in English.

$localeInterface = $objectManager- 
>create('Magento\Framework\Locale\ResolverInterface');

$localeInterface->setLocale('de_DE');
$localeInterface->setDefaultLocale('de_DE');

echo __('Some string');

Thanks !

You can translate the string into another locale using getDictionary() function of \Magento\Framework\App\Language\Dictionary class as described follows:

protected $_dictionary;

public function __construct(
    ...
    \Magento\Framework\App\Language\Dictionary $dictionary,
    ...
) {
    ...
    $this->_dictionary = $dictionary;
    ...
}

public function execute() {
    ...
    $arrString = $this->_dictionary->getDictionary('de_DE')['Some String'];
    ...
}

In $arrString variable, you will get phrase in the source code as a key and the string translation as a value.

I hope it may resolve your problem.
