嗯.如何添加css“错误"在表单提交上输入的类?

2022-01-04 00:00:00 php yii

我有 Yii 表格.某些字段是必需的.提交表单时，我需要将 CSS 类错误"添加到文本输入中.我的代码:

I have Yii form. Some fields are required. When form is submitted i need that CSS class "error" would be added to the text input. My Code:

          <?php $form=$this->beginWidget('CActiveForm', array(
                    'id'=>'contact-form',
                    'enableClientValidation'=>true,
                    'clientOptions'=>array(
                            'validateOnSubmit'=>true,
                    ),
            )); ?>
           <ul class="contact_form">
               <li class="row">
                   <?php echo $form->labelEx($model,'name'); ?>
                   <?php echo $form->textField($model,'name', array('class'=>'input')); ?>
                   <?php echo $form->error($model,'name'); ?>
               </li>
...

现在我只收到带有错误消息的 div:

Now i just get div with error message:

<div class="errorMessage" id="ContactForm_name_em_" style="">Laukelis „Vardas, pavardė" negali būti tuščias.</div>

如何将错误"类添加到输入字段?

推荐答案

要同时进行 AJAX 验证，您应该或多或少地添加如下内容:

To have AJAX validation also, you should add something more or less like this:

<?php $form=$this->beginWidget('CActiveForm', array(
          'id'=>'contact-form',
          'enableClientValidation'=>true,
          'clientOptions'=>array(
              'validateOnSubmit'=>true,
              'afterValidate' => 'js:function(form, data, hasError) { 
                  if(hasError) {
                      for(var i in data) $("#"+i).addClass("error_input");
                      return false;
                  }
                  else {
                      form.children().removeClass("error_input");
                      return true;
                  }
              }',
              'afterValidateAttribute' => 'js:function(form, attribute, data, hasError) {
                  if(hasError) $("#"+attribute.id).addClass("error_input");
                      else $("#"+attribute.id).removeClass("error_input"); 
              }'
          ),
        )); ?>
