窗口小部件设置：

DatePicker::widget([ 
    'model' => $model, 
    'attribute' => 'TANGGAL_MASUK', 
    'template' => '{addon}{input}', 
     'clientOptions' => [ 
      'autoclose' => true, 
      'format' => 'yyyy-m-d', 
      'startDate' => date('d-M-y'), 
      'prepend' => '<i class="icon-calendar"></i>' 
     ] 
    ]); 

区别是这样的：'format' => 'yyyy-m-d',（更改格式）。

现在我们从这个插件检索值。比方说，我们从Yii::$app->request->post()['Model']['TANGGAL_MASUK']得到这个值：

// Assigned to $time for easier access and converted to UNIX timestamp with strtotime() 
$time = strtotime(Yii::$app->request->post()['Model']['TANGGAL_MASUK']); 

// Let's calculate the value by adding the value of 2 days (in seconds) 
$newTime = $time + 2 * 60 * 60 * 24; 

// Let's convert back to your desired format (like: 29-Nov-16) 
$newDate = date('y-M-d', $newTime); 

现在我们有$newDate变量添加了2天包含的内容。请注意，如果您希望能够使用（添加/减去或插入数据库），则必须更改格式或使用UNIX时间戳。
