查询中的Yii2格式日期

Question

我需要将date -week_end-从yyyy-mm-dd格式化为M-d-Y。填充下拉列表。 这里是控制器的代码：

public static function getPayWeeks() 
{ 
    $droptions = PayWeeks::find()->asArray()->all(); 
    return ArrayHelper::map($droptions, 'id', 'week_end'); 
} 

这里是形式的代码：

<?php $form = ActiveForm::begin(['id' => 'payweek-form']); ?> 
    <?= $form->field($model, 'id')->dropDownList(PayWeeks::getPayWeeks(), ['prompt' => ' -- Select Week End Date --']); ?> 
      <div class="form-group"> 
       <?= Html::submitButton('Submit', ['class' => 'btn btn-primary', 'name' => 'contact-button']) ?> 
      </div> 
<?php ActiveForm::end(); ?>

你必须创建阵列时重新格式化week_end字段：

public static function getPayWeeks() 
{ 
    $droptions = PayWeeks::find()->asArray()->all(); 
    return ArrayHelper::map($droptions, 'id', function($model) { 
     return date("M-d-Y", strtotime($model['week_end'])); 
    }); 
}
