Yii2：動態表單部件wbraganca不是

我有我的Yii2項目中的3個相關表（模型）。Yii2：動態表單部件wbraganca不是

用戶具有| ID (primary key) | username |

PHONETYPE具有| ID (primary key) | typename |

Phonenumber來具有

| ID | user_ID (foreign key) | type_ID (foreign key) | phonenumbers |

我在我的Yii2應用程序中集成了「wbraganca Yii2動態表單」，但是當我點擊「創建」按鈕時，什麼都沒有發生，只是空白頁。但是，當我切入分貝我得到的用戶名是創建沒有數字。

請不要將其標記爲重複項，因爲直到現在我還沒有找到解決此問題的方法。 在此先感謝。下面

_form.php這個代碼是我create.php代碼

<?php 
use yii\helpers\Html; 

/* @var $this yii\web\View */ 
/* @var $model app\models\User */ 

$this->title = Yii::t('app', 'Создать контакт'); 
$this->params['breadcrumbs'][] = ['label' => Yii::t('app', 'Контакты'), 'url' => ['index']]; 
$this->params['breadcrumbs'][] = $this->title; 
?> 
<div class="user-create"> 

<h1><?= Html::encode($this->title) ?></h1> 

<?= $this->render('_form', [ 
'model' => $model, 
'modelsPhone'=>$modelsPhone, 
]) ?>

Here you can see that i filled all fields.Then when im clicking button, nothing happened

請避免這樣的問候和其他foofaraws。問題應儘可能純粹，以便清楚，並且易於諮詢。 –

讓我們來檢查你的controller.for的第一部分，請檢查$ valid value.is它是真是假？ – yafater

謝謝，夥計。我只是試圖修復我的規則驗證並解決了我的問題。現在一切都運轉良好。 – Miracle633

不是應該$ modelsPhone = [新Phonenumber來（）];

此外，您還需要創建一個新的MultipleModel類，該類擴展了模型，因爲不像loadMultiple和validateMultple，createMultiple方法默認包含在Model中。

<?php 

namespace common\models; 

use Yii; 
use yii\base\Model; 
use yii\helpers\ArrayHelper; 

class MultipleModel extends Model 
{ 
/** 
* Creates and populates a set of models. 
* 
* @param string $modelClass 
* @param array $multipleModels 
* @param string $pk 
* @return array 
*/ 
    public static function createMultiple($modelClass, $multipleModels = [], $pk = 'id') 
    { 
    $model = new $modelClass; 
    $formName = $model->formName(); 
    $post  = Yii::$app->request->post($formName); 
    $models = []; 

     if (!empty($multipleModels)) { 
      $keys   = array_keys(ArrayHelper::map($multipleModels, $pk, $pk)); 
      $multipleModels = array_combine($keys, $multipleModels); 
     } 

     if ($post && is_array($post)) { 
      foreach ($post as $i => $item) { 
       if (isset($item[$pk]) && !empty($item[$pk]) && isset($multipleModels[$item[$pk]])) { 
        $models[] = $multipleModels[$item[$pk]]; 
       } else { 
        $models[] = new $modelClass; 
       } 
      } 
     } 

     unset($model, $formName, $post); 

     return $models; 
    } 
}
