Question

您好我在使用Laravel 5.2时偶然发现了一个问题我不知道问题是针对5.2的特定问题还是发生在框架的其他版本中。

基本上我尝试做的是通过单个html文件输入字段上传多个文件，这就是我所拥有的。

观点：

<form method="post" action="nieuw" enctype="multipart/form-data">
    <input type="file" class="form-control" name="images" multiple>
</form>

请求文件：

public function rules()
{
    return [
        'images' => 'mimes:jpg,jpeg,png'
    ];
}

最后但并非最不重要的是控制器：

public function store(Requests\EventRequest $request)
{
    dd($request->file('images'));
}

现在，当通过输入字段上传多个文件时，这就是转储显示的内容。

UploadedFile {#30 ▼
  -test: false
  -originalName: "anotherone.jpg"
  -mimeType: "image/jpeg"
  -size: 64112
  -error: 0
  path: "/tmp"
  filename: "phpm57pCe"
  basename: "phpm57pCe"
  pathname: "/tmp/phpm57pCe"
  extension: ""
  realPath: "/tmp/phpm57pCe"
  aTime: 2016-02-25 23:46:57
  mTime: 2016-02-25 23:46:57
  cTime: 2016-02-25 23:46:57
  inode: 1443315
  size: 64112
  perms: 0100600
  owner: 900
  group: 900
  type: "file"
  writable: true
  readable: true
  executable: false
  file: true
  dir: false
  link: false
}

它似乎只是通过上传字段捕获您提交的最后一个文件。请注意，请求验证程序此时可以正常工作，您只能上传设置的mime类型，但其请求无法显示所有文件。

我自己想到的是将html输入字段设置为像这样的数组

<form method="post" action="nieuw" enctype="multipart/form-data"> <input type="file" class="form-control" name="images[]" multiple> </form>

解决了控制器端的问题，使转储看起来像这样

<form method="post" action="nieuw" enctype="multipart/form-data">
    <input type="file" class="form-control" name="images

然而，通过这种方法，验证已完全消失，我尝试将验证器更改为：

" multiple>
</form>

    readable: true
    executable: false
    file: true
    dir: false
    link: false
  }
]

他们两人都无可救药地失败了。我希望你们中的一些人可以帮助我。提前谢谢！

没有验证array iamges你可以做什么

$validator = \Validator::make($request->all(), [
  'images' => 'required'
]);
$files = $request->file('images');
foreach ($files as $file){
   $validator->after(function($validator) use ($file) {
      //make your valdiation
   });
}
if ($validator->fails()) {
   //validation didn't pass
}

另一种方式

$files = $request->file('images');
foreach ($files as $file){
   $input = ['upload' => $files[$i]];
   $rules = ['upload' => 'image|max:15500'];
   $validation = Validator::make($input, $rules);
   if($validator->fails()){
    //validation didn't pass
    break;
   }
}

第三种方法是创建自己的Validation rule

您可以像 Laravel 5.2 中的任何输入数组一样验证文件数组。此功能是Laravel 5.2中的新功能。你可以这样做：

$input_data = $request->all();

$validator = Validator::make(
    $input_data, [
    'image_file.*' => 'required|mimes:jpg,jpeg,png,bmp|max:20000'
    ],[
        'image_file.*.required' => 'Please upload an image',
        'image_file.*.mimes' => 'Only jpeg,png and bmp images are allowed',
        'image_file.*.max' => 'Sorry! Maximum allowed size for an image is 20MB',
    ]
);

if ($validator->fails()) {
    // Validation error.. 
}

注意，您也可以在控制器中使用$this->validate($request, $rules, $messages);。
