Whether to force message translation when the source and target languages are the same. Defaults to false, meaning translation is only performed when source and target languages are different.

public boolean $forceTranslation false
$sourceLanguage public property

The language that the original messages are in. If not set, it will use the value of yii\base\Application::$sourceLanguage.

public string $sourceLanguage null

方法详情 Method Details

init() public method

Initializes this component.

public void init ( )
loadMessages() protected method

If translation for specific locale code such as en-US isn't found it tries more generic en.

protected array loadMessages ( $category, $language )
$category string

The message category

$language string

The target language

return array

The loaded messages. The keys are original messages, and the values are translated messages.

translate() public method

Note that unless $forceTranslation is true, if the target language is the same as the source language, the message will NOT be translated.

If a translation is not found, a missingTranslation event will be triggered.

$category string

The message category

$message string
