我正在为我自己的项目使用wbraganca的dynamicform示例代码。我的代码及其相应的错误如下。

在视图文件夹

下 
_form.php
<?php

use yii\helpers\Html;
use yii\widgets\ActiveForm;
use yii\helpers\ArrayHelper;
use frontend\models\Items;
use frontend\models\Employees;
use frontend\models\Departments;
use dosamigos\datepicker\DatePicker;
use wbraganca\dynamicform\DynamicFormWidget;     
/* @var $this yii\web\View */
/* @var $model backend\models\Borrow */
/* @var $form yii\widgets\ActiveForm */
$js = '
jQuery(".dynamicform_wrapper").on("afterInsert", function(e, item) {

jQuery(".dynamicform_wrapper .panel-title-address").each(function(index) {

    jQuery(this).html("Items: " + (index + 1))

  });

});
jQuery(".dynamicform_wrapper").on("afterDelete", function(e) {

jQuery(".dynamicform_wrapper .panel-title-address").each(function(index) {

    jQuery(this).html("Items: " + (index + 1))

});

 });

';

 $this->registerJs($js);?>

控制器下的创建操作 

public function actionCreate()
{
    $model = new Borrow();
    $modelsAddress = [new Borrow];
    if ($model->load(Yii::$app->request->post())) {


        $modelsAddress = Model::createMultiple(Borrow::classname());

        Model::loadMultiple($modelsAddress, Yii::$app->request->post());


        // validate all models

        $valid = $model->validate();

        $valid = Model::validateMultiple($modelsAddress) && $valid;


        if ($valid) {

            $transaction = \Yii::$app->db->beginTransaction();


            try {

                if ($flag = $model->save(false)) {

                    foreach ($modelsAddress as $modelAddress) {

                        $modelAddress->id = $model->id;

                        if (! ($flag = $modelAddress->save(false))) {

                            $transaction->rollBack();

                            break;

                        }

                    }

                }


                if ($flag) {

                    $transaction->commit();

                    return $this->redirect(['view', 'id' => $model->id]);

                }

            } catch (Exception $e) {

                $transaction->rollBack();

            }

        }

    }


    return $this->render('create', [

        'model' => $model,

        'modelsAddress' => (empty($modelsAddress)) ? [new Address] : $modelsAddress

    ]);
}

模型文件夹下的模型类 

<?php
namespace frontend\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);
    }

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

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

    return $models;
 }
}

运行代码时出现以下错误： PHP Fatal Error – yii\base\ErrorException Class 'frontend\controllers\Model' not found如下所示。

看起来您在控制器中没有命名空间frontend\models\Model。

在开头添加：

use frontend\models\Model;
