如何为yii2中的特定文件启用AjaxValidtion

Question

我有以下字段只提出Ajax Valiadtion

     <?= 
        $form->field($questionModel, 
       'questions_options_order')->dropDownList(Yii::$app->controller->optionsOrderArr 
      , ['class' => 'form-control required']) 
    ?>

Answer 1

  

模型冲动

public function rules()
    {
        return [
        [['questions_options_order'], 'required'], 
       ];
    }

  

查看看起来像这样

<?= 
        $form->field($questionModel, 
       'questions_options_order')->dropDownList(Yii::$app->controller->optionsOrderArr 
      , ['prompt' => 'Select options Type']) 
    ?>

Answer 2

> Put Enable Ajaxvalidation true specific filed
 <?=
       $form->field($oModel, 'variable_file',['enableAjaxValidation' => false])->widget(FileInput::classname(), [
       'options'       => ['accept' => 'csv', 'class' => 'required file_input'],
       'pluginOptions' => ['allowedFileExtensions' => ['csv']]
         ]);
    ?>
