使用 Yii2 在数据库中提交 Activeform 数据，不工作

Question

我是 yii2 框架的新手，当我提交我的 Activeform 数据以保存在数据库中时显示错误

未找到 (#404)。

此 Activeform 在不同的模型视图中提及。我的表格在产品页面上，我只想就该产品对客户进行评论并保存在数据库中。

查看文件：detail.php：

    <?php
    use yii\helpers\Html;
    use yii\widgets\DetailView;
    use yii\widgets\ActiveForm;

    /* @var $model app\models\Product */

    $name = $result->name;

         $price = $result->price;
         $offerrate = 8;
         $offer = ($price / 100) * $offerrate;
         $offerprice = number_format($price - $offer, 2);

         $text = $result->Description;
         $list = explode(",", $text);
    ?>

Answer 1

控制器动作的命名约定基于-分隔符，当部分为大写时，您应该使用

 <?php $form = ActiveForm::begin(['id' => 'reviewForm', 
         'action' => Yii::$app->urlManager->createUrl(['Tbl-feedback/create'])]); ?>

命名约定，对于控制器来说，是以小写字母开头的。

所以你应该使用

   class tblFeedbackController extends \yii\web\Controller

和

      <?php $form = ActiveForm::begin(['id' => 'reviewForm', 
         'action' => Yii::$app->urlManager->createUrl(['tbl-feedback/create'])]); ?>

最后一个建议你可以使用 urlHelper

use yii\helpers\Url;

      <?php $form = ActiveForm::begin(['id' => 'reviewForm', 
         'action' => Url::to(['tbl-feedback/create'])]); ?>
