如何为DateValidation添加错误消息？

Question

在我的模型我用DateValidation

['date_birthday', 'date', 'format' => 'd.m.yy', 'min' => '01.01.1900', 'max' => date('d.m.yy'), 'tooSmall'=>'The date is from past. Try another','tooBig' => 'The date is from future. Try another', 'message' => 'Try to input the date'], 

鉴于我所说的小部件

<?php echo $form->field($modelForm, 'date_birthday')->widget(\kartik\date\DatePicker::classname(), [ 
         'type' => \kartik\date\DatePicker::TYPE_COMPONENT_APPEND, 
         'pickerButton' => false, 
         'options' => [ 
          'placeholder' => '', 
         ], 
         'pluginOptions' => [ 
          'format' => 'dd.mm.yyyy', 
          'autoclose' => true, 
          'showMeridian' => true, 
          'startView' => 2, 
          'minView' => 2, 
         ] 
        ]) ?> 

它检查最小和最大日期，但没有显示错误消息。我认为它是因为模型和视图中的日期格式不同。如何解决它？

Answer 1

如果您提交表单，您将看到错误消息。根据这个问题https://github.com/yiisoft/yii2/issues/7745 yii2没有客户端验证日期

您可以启用ajax验证。在语句前加入创建和更新动作

if (Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())) { 
    Yii::$app->response->format = yii\web\Response::FORMAT_JSON; 
    return ActiveForm::validate($model); 
} 

并在控制器类的顶部添加使用yii\widgets\ActiveForm;。在您的_form.php文件来实现AJAX的整个形式

<?php $form = ActiveForm::begin([ 
    'enableAjaxValidation' => true, 
]); ?> 

，或者现场只有

<?php echo $form->field($model, 'date_birthday', ['enableAjaxValidation' => true])->widget(\kartik\date\DatePicker::classname(), [ 
... 

此外，您还可以添加插件选项限制日期的startDate和结束日期（https://bootstrap-datepicker.readthedocs.io/en/latest/options.html#startdate）

<?php echo $form->field($model, 'date_birthday', ['enableAjaxValidation' => true])->widget(\kartik\date\DatePicker::classname(), [ 
        'type' => \kartik\date\DatePicker::TYPE_COMPONENT_APPEND, 
        'pickerButton' => false, 
        'options' => [ 
         'placeholder' => '', 
        ], 
        'pluginOptions' => [ 
         'format' => 'dd.mm.yyyy', 
         'autoclose' => true, 
         'showMeridian' => true, 
         'startView' => 2, 
         'minView' => 2, 
         'startDate' => '01.01.1900', 
         'endDate' => date('d.m.Y'), 
        ] 
       ]) ?>
