laravel 8 api：更新帖子时从文件夹中删除文件

Question

我有帖子表并为它上传图片，所以在PostController() 的update() 方法中我想编辑帖子和图片

为了编辑图像，我想从文件夹和数据库中删除最后的图像，并替换新图像。

所以我可以从数据库中删除最后的图像，但我不能从文件夹中删除它们

控制器：

public function update(StorePostRequest $request , $id )
    {

        $validatedData = $request->all();

        if ($request->hasfile('image')) {

            $postTitle = $request->title; //post title for folder name and the images inside it

            //delete last Images from database for updating images
            Image::where('imageable_type' , 'App\Models\Post')->where('imageable_id' , $id)->delete();

             $directory =storage_path().'/images/posts/'.$postTitle;
            if($directory){
                Storage::disk('public')->deleteDirectory('images/posts/.$postTitle');
            }


            $files = $request->file('image');

            foreach ($files as $file) {

                $imageName = time().rand(1,10000).'.'.$file->extension();

                $postTitle = $request->title; //post title for folder name and the images inside it
                $imagePath = public_path(). '/images/posts/'.$postTitle;

                $file->move($imagePath, $imageName);

                $image = new Image;
                $image->image = $imageName;
                $image->path = $imagePath;

                $images[] = $image; // make an array of uploaded images
            }
        }

        $post = Post::find($id);

        $post->category_id = $validatedData['category_id'];
        $post->title = $validatedData['title'];
        $post->body = $validatedData['body'];
        $post->study_time = $validatedData['study_time'];

        $post->save();
        $post->images()->saveMany($images);

        return response()->json([
        "success" => true,
        "message" => "successfully",
        "data" => $post
        ]);
    }

帖子和图片之间的关系是：一对多的多态，我用邮递员来品尝它

我试过这种方法，但它不起作用：

             File::delete(public_path('/images/posts/'.$postTitle));

             Storage::disk('public')->deleteDirectory($directory);

另外，当我尝试时

       Storage::disk('public')->deleteDirectory('images/posts/');

它可以工作并且帖子文件夹已被删除，但问题来自$postTitle

当我使用它时，它不起作用

Answer 1

您可以使用此代码删除文件

if (!is_dir(public_path('/images/posts/'.$postTitle))) {
    mkdir(public_path('/images/posts/'.$postTitle));
}

Answer 2

如果您需要删除目录，请使用Storage::disk('public')->deleteDirectory('images/posts');
