使用 DynamicFormWidget - Yii2 验证唯一的电子邮件

Question

我对多个输入字段使用 DynamicFormWidget，例如：first_name、last_name、email 和 mobile_no。而且，我不希望用户键入现有的 email。意思是，email 应该是唯一的。它在我不使用 DynamicFormWidget 时工作。实际上，我不知道如何使用 Yii2 验证多个输入表单中的唯一电子邮件。

addmembers.php（查看）

<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
use wbraganca\dynamicform\DynamicFormWidget;
?>

<?php DynamicFormWidget::begin([
'widgetContainer' => 'dynamicform_wrapper',
'widgetBody' => '.container-items',
'widgetItem' => '.house-item',
'limit' => 10,
'min' => 1,
'insertButton' => '.add-house',
'deleteButton' => '.remove-house',
'model' => $modelsTeamMembers[0],
'formId' => 'dynamic-form',
'formFields' => ['description',],
]); ?>

<table class="table table-bordered table-striped">
<thead>
  <tr>
    <th>First Name</th>
    <th>Last Name</th>
    <th>Email</th>
    <th>Mobile Number</th>
  </tr>
</thead>
<tbody class="container-items">
<?php foreach ($modelsTeamMembers as $indexMember => $modelTeamMembers): ?>
    <tr class="house-item">
      <td class="vcenter">
        <?php
        if (! $modelTeamMembers->isNewRecord) {
          echo Html::activeHiddenInput($modelTeamMembers, "[{$indexMember}]id");
        }
        ?>
        <?= $form->field($modelTeamMembers, "[{$indexMember}]first_name")->label(false) ?>
      </td>
      <td>
        <?= $form->field($modelTeamMembers, "[{$indexMember}]last_name")->label(false) ?>
      </td>
      <td>
        <?= $form->field($modelTeamMembers, "[{$indexMember}]email",['enableAjaxValidation' => true])->label(false) ?>
      </td>
      <td>
        <?= $form->field($modelTeamMembers, "[{$indexMember}]mobile_no",['inputOptions' => ['class' => 'form-control', 'maxlength'=>"10"]])->label(false) ?>
      </td>
    </tr>
 <?php endforeach; ?>

UsersController.php（控制器）

<?php
namespace app\modules\users\controllers;

use Yii;
use yii\web\NotFoundHttpException;
use yii\filters\VerbFilter;
use yii\swiftmailer\Mailer;
use yii\filters\AccessControl;
use yii\web\Response;
use yii\widgets\ActiveForm;

class UsersController extends CommonController 
{
    public function actionAddmembers() {

        if(Yii::$app->request->isAjax && $modelUser->load(Yii::$app->request->post())) {
          Yii::$app->response->format = Response::FORMAT_JSON;
          return ActiveForm::validate($modelUser);
        } 
        elseif ($modelUser->load(Yii::$app->request->post())) {
            .
            .
        }

    }
}

Users.php（型号）

namespace app\modules\users\models;

use Yii;
use app\models\MyActiveRecord;
use yii\web\IdentityInterface;

class Users extends MyActiveRecord implements IdentityInterface
{

  public $rememberMe;
  public $confirm_password;
  public $verify_code;
  public $_user = false;

  public static function tableName() {
    return 'users';
  }

  public function rules() {
    return [

      .
            .
      //Email ID
      'emailTrim' => ['email', 'filter', 'filter' => 'trim'],
      'emailRequired' => ['email', 'required','message'=>'* required field'],
      'emailPattern' => ['email', 'email'],
      'emailUnique' => ['email', 'unique','message'=>'Email already exists!'],
        ];
  }
  .
  .
  .
}

我也试过：

UsersController.php（控制器）

public function actionAddmembers() {

  $modelUser = new Users();
  $modelCompanyUser = new CompanyUsers();
  $modelCompany = new Company();
  $modelsTeamMembers = [new Users]; 

  $modelUserDetails = MyActiveRecord::createMultiple(Users::classname());
  MyActiveRecord::loadMultiple($modelUserDetails, Yii::$app->request->post());

    if (Yii::$app->request->isAjax) {
      Yii::$app->response->format = Response::FORMAT_JSON;
      return ArrayHelper::merge(ActiveForm::validateMultiple($modelUserDetails));
    } elseif($modelUser->load(Yii::$app->request->post())){
        .
        .
    }
}

我关注yii2-dynamicform

任何 help/hint/suggestion 都将是可观的。

Answer 1

是的。我知道了。如果有人遇到同样的问题，请使用此代码。请在需要的地方更改 $modelUserDetails 变量。

我正在使用 DynamicFormWidget。

而且，我想在 email 字段上 检查电子邮件是否存在 。所以，

addmembers.php（查看）

在页面顶部使用 use yii\widgets\ActiveForm;。并且，将 'enableAjaxValidation' => true 放在您希望用户限制输入重复值的字段中。

use yii\widgets\ActiveForm; // This is mandatory.
.
.
<?= $form->field($modelTeamMembers, "[{$indexMember}]email",['enableAjaxValidation' => true]);?>
.
.

UsersController.php（控制器）

<?
// These two lines are mandatory. 
use yii\web\Response;
use yii\widgets\ActiveForm;

..

public function actionAddMembers() {

   .
   .
   $modelUserDetails = MyActiveRecord::createMultiple(Users::classname());
   MyActiveRecord::loadMultiple($modelUserDetails, Yii::$app->request->post());

   // ajax validation
   if (Yii::$app->request->isAjax) {

     Yii::$app->response->format = Response::FORMAT_JSON;
     return ActiveForm::validateMultiple($modelUserDetails);

   } elseif ($modelUser->load(Yii::$app->request->post())) {
        // Business Logic
   }
}

Users.php（型号）

class Users extends MyActiveRecord implements IdentityInterface
{
    .
    .
    .

    public function rules() {
    return [
            .
            .
            ['email', 'unique','message'=>'Email already exists!'],
        ];
  }

}

一定会有帮助。
