How can i get the correct file extension in laravel 5.4
提问by mojoblanco
When I upload a csv file in laravel 5.4, I get 'txt' as the extension. Is there something I'm missing?
当我在 laravel 5.4 中上传一个 csv 文件时，我得到了“txt”作为扩展名。有什么我想念的吗？

{!! Form::open(['url' => 'transaction/save', 'files' => true]) !!}
{!! Form::file('batch'); !!}
{!! Form::submit('Upload') !!}
{!! Form::close() !!}
Controller
控制器
public function saveBatch(Request $request)
{
$file = $request->batch;
$path = $request->batch->extension();
dd($path);
}

You need to move the file first, if you don't then the file is actually a temp file with no extension. You could also use:
您需要先移动文件，否则该文件实际上是一个没有扩展名的临时文件。您还可以使用：
$request->batch->getClientOriginalExtension();
This would return the original filename's extension. More methods at: http://api.symfony.com/3.0/Symfony/Component/HttpFoundation/File/UploadedFile.html
这将返回原始文件名的扩展名。更多方法请访问：http: //api.symfony.com/3.0/Symfony/Component/HttpFoundation/File/UploadedFile.html

The best way to get the extension of uploaded file: (If file input name is file)
获取上传文件扩展名的最佳方法：（如果文件输入名称是文件）
$extension = $request->file->extension();
