我是yii和php的新手.我想上传一个文件并将其路径保存到数据库,但这样做我得到一个错误.

我的控制器类是:

public function actionCreate()

            $model->save();
            return $this->redirect(['view', 'id' => $model->idQuiz]);
        } else {
            return $this->render('create', [
                'model' => $model,
            ]);

        }
    }

<?php

use yii\helpers\Html;
use yii\widgets\ActiveForm;

/* @var $this yii\web\View */
/* @var $model app\models\Quiz */
/* @var $form yii\widgets\ActiveForm */
?>

<div class="quiz-form">

    <?php $form = ActiveForm::begin(['option' => ['enctype' => 'multipart/form-data']]); ?>

    <?= $form->field($model, 'Course_idCourse')->textInput(['maxlength' …
