How to delete a file physically in Yii2 by linked table in a loop?

Question

Yii

standard delete function

public function actionDelete($id)
    {
        $this->findModel($id)->delete();
        return $this->redirect(['advbyuser']);
    }

There is a related image table from which you need to delete rows in a cycle along with pictures when deleting an ad, and at the end the pictures folder itself. Pictures
path - example: @web/upload/store/Adverts/Adverts8/
b0cd8f.jpg I know how it will work. But something can't be done

Answer 1

Good afternoon.
Is there a foreign key relationship?
If it is, then when the record is deleted, the records from the image table will be deleted.
And the directory can be deleted like this:

public function actionDelete($id)
    {
        if($this->findModel($id)->delete()){
           FileHelper::removeDirectory($path_to_dir);
        }
        return $this->redirect(['advbyuser']);
    }

Or do this:

public function beforeDelete()
    {
        if(!parent::beforeDelete()){
            return false;
        }
        $path = 'path_to_dir';
        FileHelper::removeDirectory($path);
        return true;
    }

Answer 2

In the afterDelete() method; set the necessary logic of actions after deleting the entry, namely, the physical deletion of the file and its parent directories (provided that they are empty).
