Question

我正在将多文件数组上传到Laravel中的服务器。

使用$request->file('files')登录文件时，我得到：

[2018-11-12 16:10:03] local.DEBUG: array (
  0 => 
  Illuminate\Http\UploadedFile::__set_state(array(
     'test' => false,
     'originalName' => 'test-pdf.pdf',
     'mimeType' => 'application/pdf',
     'error' => 0,
     'hashName' => NULL,
  )),
  1 => 
  Illuminate\Http\UploadedFile::__set_state(array(
     'test' => false,
     'originalName' => 'test-pdf.pdf',
     'mimeType' => 'application/pdf',
     'error' => 0,
     'hashName' => NULL,
  )),
  2 => 
  Illuminate\Http\UploadedFile::__set_state(array(
     'test' => false,
     'originalName' => 'test-pdf.pdf',
     'mimeType' => 'application/pdf',
     'error' => 0,
     'hashName' => NULL,
  )),
)

我想访问数组中的每个文件并像这样获取路径名：

$files = $request->files;
foreach ($files as $key => $file) {
  Log::debug($file->getPathName());
}

但是这会引发以下错误：

local.ERROR: Call to a member function getPathName() on array {"exception":"[object] (Symfony\\Component\\Debug\\Exception\\FatalThrowableError(code: 0): Call to a member function getPathName() on array at /home/vagrant/Projects/business-risk-portal/app/Http/Controllers/FileController.php:68)

如何访问每个上载文件的文件路径？

更新如果我尝试这样做：

$files = $request->files;
foreach ($files as $key => $file) {
   $temp_path = $request->file('tmp.' . $key);
   Log::debug($temp_path->getPathName());
}

我得到：

Call to a member function getPathName() on null {"exception":"[object] (Symfony\\Component\\Debug\\Exception\\FatalThrowableError(code: 0): Call to a member function getPathName() on null at /home/vagrant/Projects/business-risk-portal/app/Http/Controllers/FileController.php:69)

Answer 1

$request->files将返回所有文件的多维数组，而$request->file('files')将仅返回与files输入有关的文件的数组。

Answer 2

这对我有用：

服务器端：

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

foreach($files as $file) {
    $target = $file->move(storage_path('files'), $file->getClientOriginalName());
    $path = $target->getPath() . DIRECTORY_SEPARATOR . $target->getFileName();
}

查看：

<form method="post" action="/myfiles" enctype="multipart/form-data">
    {{csrf_field()}}
    <input type="file" name="myfiles[]" class="form-control" multiple />
    <button type="submit" class="btn btn-success">Save</button>
</form>

在数组上调用成员函数getPathName（）
