yii\i18n\PhpMessageSource::loadMessages

[endachao]

log:

The message file for category 'yii' does not exist: /Applications/MAMP/htdocs/phpcto/trunk/application/admin/vendor/yiisoft/yii2/messages/zh/yii.php

web.php 
    'language' => 'zh_CN',

What reason is this error?

PhpMessageSource 

:72 line
protected function loadMessages($category, $language) 

// Why the truncation
$fallbackLanguage = substr($language, 0, 2);

zh_CN => zh 

message /  
zh 
 This folder is not useful

[samdark]

It tries zh_CN then if it doesn't exist it tries to fallback to zh. Same for all languages: en_US -> en, en_AU => en etc. It's strange that it goes to fallback for you. Probably messages for zh_CN are a bit outdated.

zh_CN This file is present

[lynicidn]

what is sourceLanguage u have? also zh?

[cebe]

Note that the file in yii2\messages is zh-CN not zh_CN, maybe thats a problem? Guess we need a normalization for the locale. Same fix might need to be applied here: https://github.com/yiisoft/yii2-jui/blob/master/DatePicker.php#L152

@cebe yes good !

[samdark]

@cebe ICU locale could be quite precise such as fr@collation=phonebook;calendar=islamic-civil. Any suggestion on where to put method extracting language from it?

[cebe]

yii\i18n\I18N would be a good place imo.
