Question

我需要创建2个删除功能（相册和照片）。不知何故，它在控制器中只有一个删除功能。如何在控制器中创建2删除功能？我仍然是OOP和Yii2的初学者。

这些是我要解释的示例。

GalleryController.php

public function actionDelete($id)
{
    $this->findModel($id)->delete();

    return $this->redirect(['index']);
}

public function actionDeletePhoto($id)
{
    $this->findModelPhoto($id)->delete();

    return $this->redirect(['index']);
}

Answer 1

尝试一下：

视图：

<?= Html::a('<i class="fa fa-trash"></i>',
    ['/controller/delete-photo'],
    [
        'class' => 'photo-dlt',
        'title' => Yii::t('app', 'Delete photo'),
        'data' => [
            'method' => 'post',
            'confirm' => Yii::t('app', 'Do you want to delete this photo?'),
            'params' => ['id' => $photo->id],
        ],
    ]
); ?>

在控制器中

public function behaviors()
    {
        return [
            'verbs' => [
                'class' => VerbFilter::className(),
                'actions' => [
                    'delete' => ['POST'],
                    'delete-photo' => ['POST'] // add this line of code
                ],
            ],
        ];
    }

public function actionDeletePhoto()
    {
        $path = "path/to/photo";

        $id = Yii::$app->request->post('id');
        $model = $this->findModelPhoto($id);
        unlink($model->image, $path);
        $model->delete();

        return $this->redirect(['index']);        
    }

Answer 2

尝试这种方式：

public function actionDelete($id)
{
    $this->findModel($id)->delete();
    $this->findModelPhoto($id)->delete();

    return $this->redirect(['index']);
}

或有另一种方法，有时删除可能会引起问题，因此在数据库中再添加一个称为“状态”的列，并将其设置为1表示活动，而将0设置为被动，则可以通过轻松更改它们的作用来创建行状态如下：

    public function actionDelete($id)
{
    $model = Model::find()->where(['id'=>$id])->one();

    $model->status=0;
    $model->save(false);
    Yii::$app->session->setFlash('danger', "smth is deleted!");
    return $this->redirect(['index']);
}
