Laravel 上传多个文件

Question

我正在构建一个具有多个文件功能的画廊。

到目前为止，我遇到了两个问题，但让我们先粘贴我的代码。

控制器：

public function store(Request $request)
{

  $gallery = new GalleryImage();

  if($request->hasFile('image')) {
    $images = $request->file('image');
    foreach($images as $image) {
      $path = $image->getClientOriginalName();
      $name = time() . '-' . $path;
      $gallery->image = $image->move(public_path().'/uploads/temp/', $name);
      //$gallery->image = $request->file('image')->storeAs('public/gallery-images', $name);
    }
  }

  $gallery->gallery_id = $request->gallery_id;

  $gallery->save();

  return back()->with('success_message','Images has been uploaded!');
}

查看刀片：

    <form action="{{ route('gallery-images.store') }}" method="POST" enctype="multipart/form-data">
      {{ csrf_field() }}
      <div class="form-group">
        <input type="hidden" name="gallery_id" value="{{ $gallery->id }}">
        <input type="file" name="image[]" id="id_imageGallery" class="form-control" multiple="multiple" required>
      </div>
      <div class="form-group">
        <button type="submit" class="btn btn-primary">Upload</button>
      </div>
    </form>

当我有这样的代码并上传三个文件时，我的第一个问题是，它成功地将文件存储到 /uploads/temp 目录中，但是在我的数据库中我可以看到只有一个图像上传，而不是三个。

我的第二个问题是当我更改代码并使用注释部分时（因为我想将这三个图像存储到存储中）：

$gallery->image = $request->file('image')->storeAs('public/gallery-images', $name);

我收到此错误：

Call to a member function storeAs() on array

如何将多张图片上传到 Storage 文件夹并全部记录到数据库中？

-- 编辑-- 我已经解决了我的第一个问题！

我只是将保存方法和其他细节放在循环中。我之前应该考虑过这个:)

这是我更新的代码：

public function store(Request $request)
{


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

    $images = $request->file('image');
    foreach($images as $image) {
      $gallery = new GalleryImage();
      $path = $image->getClientOriginalName();
      $name = time() . '-' . $path;
      $gallery->image = $image->move(public_path().'/uploads/temp/', $name);
      //$gallery->image = $request->file('image')->storeAs('public/gallery-images', $name);

      $gallery->gallery_id = $request->gallery_id;
      $gallery->save();
    }
  }


  return back()->with('success_message','Images has been uploaded!');
}

现在唯一要做的就是如何将它们存储到文件存储中，而不是 public_path 并避免该错误：

Call to a member function storeAs() on array

尝试使用以下代码实现，它会以序列化格式给出上传文件的url

    public static function upload_file($file){
        $file_name = time();
        $file_name .= rand();
        $file_name = sha1($file_name);
        if ($file) {
            $ext = $file->getClientOriginalExtension();
            $file->move(public_path() . "/uploads", $file_name . "." . $ext);
            $local_url = $file_name . "." . $ext;
            $s3_url = url('/').'/uploads/'.$local_url;
            return $s3_url;
        }
        return "";
    }

    public static function upload_multiple_files($files){
        if(is_array($files)){
            $return_array = array();
            foreach ($files as $file){
                if(!empty($file)){
                    $return_array[] = self::upload_file($file);
                }else{
                    $return_array[] = '';
                }
            }
            return serialize($return_array);
        }else{
            return NULL;
        }
    }

//我已经更新并评论了你的代码。试试看，应该可以的。

public function store(Request $request)
    {
      if($request->hasFile('image')) {

        $images = $request->file('image');
        foreach($images as $image) {
          $gallery = new GalleryImage();
          // laravel auto manages unique name and extension of file.
          $gallery->image = $image->store('gallery-images', 'public'); 
          $gallery->gallery_id = $request->gallery_id;
          $gallery->save();
        }
      }
      return back()->with('success_message','Images has been uploaded!');
    }

我终于解决了这些问题，我正在发布它，所以它可能对某些人有用。

这是我的代码：

public function store(Request $request)
{

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

    foreach($request->image as $image) {
      $path = $image->getClientOriginalName();
      $name = time() . '-' . $path;

      $gallery = new GalleryImage();
      $gallery->image = $image->storeAs('public/gallery-images', $name);
      $gallery->gallery_id = $request->gallery_id;
      $gallery->save();
    }
  }

  return back()->with('success_message','The images have been uploaded!');
}
