I noticed the following differences when using jQuery-UI Datepicker. Formatter was providing the date input's initial value on page load and the format changed after using Datepicker.
Both are ICU 'medium'.
| locale | asDate() | convertDateIcuToJui() |
| --- | --- | --- |
| en-US | Apr 4, 2015 | Apr 4 2015 |
| ru-RU | 04 邪胁谐. 2015 谐. | 04 袗胁谐 2015 谐. |
or something like that
I am unable to reproduce this, do you have the PHP intl extension installed?
The discrepancy has changed since I last tested it.
intl 1.1.0
ICU 52.1
PHP 7.0.11
In app config
'language' => 'ru-RU',
Model and controller
<?php
class TestForm extends \yii\base\Model
{
public $date = '2016-11-27';
}
class TestController extends \yii\web\Controller
{
public function actionTest()
{
return $this->render('test', ['model' => new TestForm()]);
}
}
View
<?php $form = \yii\widgets\ActiveForm::begin(); ?>
<?= $form->field($model, 'date')->widget(\yii\jui\DatePicker::className(), ['dateFormat' => 'medium']) ?>
<?php \yii\widgets\ActiveForm::end(); ?>
Initial page load

Click on 27 Nov in the date picker

Date is now formatted as

i cannot be sure that intl was installed when i ran the test in aug last year but it most likely was because i have required it as standard for years

@bscheshirwork thanks for the detailed research. I just looked into the jquery UI sources and found that they have hardcoded the month names:

So... This issue can be moved to yiisoft/yii2-jui and can be remove from milestone 2.0.13?
