|
* DatePicker renders a datepicker jQuery UI widget.
|
|
|
|
*
|
|
|
|
* For example:
|
|
|
|
*
|
|
|
|
* ```php
|
|
|
|
* echo DatePicker::widget([
|
|
|
|
* 'language' => 'ru',
|
|
|
|
* 'model' => $model,
|
|
|
|
* 'attribute' => 'country',
|
|
|
|
* 'clientOptions' => [
|
|
|
|
* 'dateFormat' => 'yy-mm-dd',
|
|
|
|
* ],
|
|
|
|
* ]);
|
|
|
|
* ```
|
|
|
|
*
|
|
|
|
* The following example will use the name property instead:
|
|
|
|
*
|
|
|
|
* ```php
|
|
|
|
* echo DatePicker::widget([
|
|
|
|
* 'language' => 'ru',
|
|
|
|
* 'name' => 'country',

|
* 'clientOptions' => [

|
* 'dateFormat' => 'yy-mm-dd',
