yii dynamic form两个参数应该具有相同数量的元素

Question

我已经安装了wbraganca / yii2-dynamicform小部件，我的创建功能运行良好，但我正在尝试更新表单，它给了我错误：“array_combine（）：两个参数应该具有相同数量的元素”从这行代码：

if (! empty($multipleModels)) {
        $keys = array_keys(ArrayHelper::map($multipleModels, 'id', 'id'));

             --> this line is causing the error:--> $multipleModels = `array_combine($keys, $multipleModels)`

让我分享一下我的controlelr update和model.php

这是我的更新代码：

 public function actionUpdate($id)
    {
        $model = $this->findModel($id);
        $modelsPoItem = $model->addressess;

        if ($model->load(Yii::$app->request->post()) && $model->save()) {

            $oldIDs = ArrayHelper::map($modelsPoItem, 'id', 'id');
            $modelsPoItem = Model::createMultiple(Poitem::classname(), $modelsPoItem);
            Model::loadMultiple($modelsPoItem, Yii::$app->request->post());
            $deletedIDs = array_diff($oldIDs, array_filter(ArrayHelper::map($modelsPoItem, 'id', 'id')));


            // validate all models
            $valid = $model->validate();
            $valid = Model::validateMultiple($modelsPoItem) && $valid;

            if ($valid) {
                $transaction = \Yii::$app->db->beginTransaction();
                try {
                    if ($flag = $model->save(false)) {
                        if (! empty($deletedIDs)) {
                            Poitem::deleteAll(['id' => $deletedIDs]);
                        }
                        foreach ($modelsPoItem as $modelPoItem) {
                           $modelPoItem->id = $model->id;
                            if (! ($flag = $modelPoItem->save(false))) {
                                $transaction->rollBack();
                                break;
                            }
                        }
                    }
                    if ($flag) {
                        $transaction->commit();
                        return $this->redirect(['view', 'id' => $model->id]);
                    }
                } catch (Exception $e) {
                    $transaction->rollBack();
                }
            }
        }

        return $this->render('update', [
            'model' => $model,
            'modelsPoItem' => (empty($modelsPoItem)) ? [new Poitem] : $modelsPoItem,

        ]);
    }

以下是错误产生的模型：

<?php

namespace app\models;

use Yii;
use yii\helpers\ArrayHelper;

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

        if (! empty($multipleModels)) {
            $keys = array_keys(ArrayHelper::map($multipleModels, 'id', 'id'));

                  $multipleModels = array_combine($keys, $multipleModels); 
            // $multipleModels = array_combine($keys, $multipleModels);

        }

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

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

        return $models;
    }
}

最后，让我向您呈现我的观点：

 <div class="col-sm-4">
     <?= $form->field($model, 'gallamay')->textInput() ?>
     <?= $form->field($model, 'gallashart')->textInput() ?>
     <?= $form->field($model, 'galla_given')->textInput() ?>

     <?= $form->field($model, 'galla_done')->widget(SwitchInput::classname(), [
         'pluginOptions'=>[
             'handleWidth'=>70,
             'onText'=>'Бажарилди',
             'offText'=>'Бажарилмади',
             'onColor' => 'primary',
             'offColor' => 'danger',
             'size' => 'mini',
             'display'=>'none',
         ]
     ]);
     ?>



<?= $form->field($model,'date')->widget(DatePicker::className(),['dateFormat' => 'php:Y-m-d'])->textInput(['placeholder' => 'Дата']); ?>
