A message source stores message translations in some persistent storage.
Child classes should override loadMessages() to provide translated messages.

Property Details
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.
The language that the original messages are in. If not set, it will use the value of yii\base\Application::$sourceLanguage.
Method Details
Initializes this component.
| public void init ( ) |
Loads the message translation for the specified language and category.
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. |
|---|---|---|
Translates a message to the specified language.
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.
| public string|boolean translate ( $category, $message, $language ) | ||
| $category | string | The message category |
| $message | string | The message to be translated |
| $language | string | The target language |
| return | string|boolean | The translated message or false if translation wasn't found or isn't required |
|---|---|---|
Translates the specified message.
If the message is not found, a missingTranslation event will be triggered.
If there is an event handler, it may provide a fallback translation.
If no fallback translation is provided this method will return false.
| protected string|boolean translateMessage ( $category, $message, $language ) | ||
| $category | string | The category that the message belongs to. |
| $message | string | The message to be translated. |
