如何在场景中为具有ajax验证的字段设置验证消息？ - Yii2

Question

我正在为2个表单使用一个模型文件.一个用于SIGNUP和其他用于一个dding成员.

我没有为SIGNUP表单设置任何场景.但是,设置了添加成员表单的方案.

模型

public function rules() {
  return [

    //Add Members
    ['first_name', 'required','message'=>'Please enter first name.','on'=>'addteammembersidebar'],
    ['email', 'required','message'=>'Please enter email address.','on'=>'addteammembersidebar'],
    ['mobile','required','message'=>'Please enter mobile number.','on'=>'addteammembersidebar'],

    //Common
    ['first_name', 'required','message'=>'Please enter your first name.'],
    ['email', 'required','message'=>'Please enter your email address.'],
    ['mobile','required','message'=>'Please enter your mobile number.'],

  ];
}

视图

在这里,我设置了场景$modelTeamMembers->scenario = 'addteammembersidebar';.

<?php foreach ($modelsTeamMembers as $indexMember => $modelTeamMembers): 
  $modelTeamMembers->scenario = 'addteammembersidebar';
  ?>
  <tr class="house-item">
    <td class="vcenter">
      <?php
      // necessary for update action.
      if (! $modelTeamMembers->isNewRecord) {
        echo Html::activeHiddenInput($modelTeamMembers, "[{$indexMember}]id");
      }
      ?>

      <?php 
      $modelTeamMembers->first_name = $first_name;
      echo $form->field($modelTeamMembers, "[{$indexMember}]first_name")->label(false); 
      ?>
    </td>
    <td>
      <?php
      $modelTeamMembers->last_name = $last_name;
      echo $form->field($modelTeamMembers, "[{$indexMember}]last_name")->label(false); 
      ?>
    </td>
    <td>
      <?php
      $modelTeamMembers->email = $email;
      echo $form->field($modelTeamMembers, "[{$indexMember}]email",['enableAjaxValidation' => true])->label(false); 
      ?>
    </td>
    <td>
      <?php
      $modelTeamMembers->mobile = $mobile_number;
      echo $form->field($modelTeamMembers, "[{$indexMember}]mobile",
          ['inputOptions' => ['class' => 'form-control', 'maxlength'=>"10"]])->label(false);
      ?>
    </td>
  </tr>

<?php endforeach; ?>

除email字段外,所有验证错误消息均有效.如果,我'enableAjaxValidation' => true从现场删除,它的工作原理.但是,对我来说'enableAjaxValidation' => true是必需的.

图片

与图像一样,可以清楚地看到错误消息" 请输入您的电子邮件地址. "应该是" 请输入电子邮件地址. ".只有email字段验证错误消息不正确.除了一切都很好.

如何email为场景设置验证消息？任何帮助/提示/建议都很明显.

Answer 1

我可以知道为什么你需要AjaxValidation在这里使用电子邮件验证吗？对于这种类型,只要AjaxValidation你想从数据库或其他模型中搜索和检索数据而不是模型本身,就更适合在没有它的情况下编写.

但是,如果您认为自己需要AjaxValidation,则必须设置一些不同的内容,因为您当前的代码将无效.

AjaxValidation在视图中设置:

// Set to: index.php?r=profile/email-validation
$form = ActiveForm::begin(['validationUrl' => ['profile/email-validation']]);

// This is set correctly (no changes are needed comparing to your attempt)
echo $form->field($modelTeamMembers, "[{$indexMember}]email", ['enableAjaxValidation' => true])->label(false);

为什么需要这个？您已设置AjaxValidation为活动状态,但尚未设置此Ajax可以使用的URL.它ActiveForm::begin()在大多数情况下都是设定的.

AjaxValidation在Controller中设置(必需):

// Method that renders your view file
public function actionSomethingThatRendersView()
{
    // Code here
    $user->scenario = 'addteammembersidebar';                 // Custom scenario name
    return $this->render(/* the remaining code goes here */);
}

// This is the method that Ajax will send request to ($_POST[])
public function actionEmailValidation()
{
    $post = Yii::$app->request->post();
    if (!empty($post))
    {
        Yii::$app->response->format = Response::FORMAT_JSON;  // Must be in JSON format
        $profile = new User();                                // Edit your class name in here
        // Custom scenario (must be the same as above otherwise you might get unexpected response)
        $profile->scenario = 'addteammembersidebar';
        $profile->load($post);

        return ActiveForm::validate($profile);
    }
}

为什么需要这个？Ajax将发送请求,但没有任何操作的请求将不会执行任何操作.这将"创建具有相同规则和属性的新对象",并将尝试使用新的数据集进行验证.对于渲染方法,$obj->scenario还必须设置,否则它将使用默认方案.

模型没有变化.一切都应该保持与你的例子相同.

如果您想要制作唯一的电子邮件,您还必须对模型进行更改:

public function rules()
{
    // ...
    ['email', 'unique', 'message' => 'Email must be unique'],
    // If your attribute is not in the same table as defined in class, then:
    ['email', 'unique', 'message' => 'Email must be unique', 'targetClass' => User2::className()],
}
