- To get the file name, as mentioned in the docs:
- 要获取文件名，如文档中所述：
You may access uploaded files that are included with the Illuminate\Http\Request instance using the file method. The object returned by the file method is an instance of the Symfony\Component\HttpFoundation\File\UploadedFile class, which extends the PHP SplFileInfo class and provides a variety of methods for interacting with the file
There are a variety of other methods available on UploadedFile instances. Check out the API documentation for the classfor more information regarding these methods.
您可以使用 file 方法访问包含在 Illuminate\Http\Request 实例中的上传文件。file方法返回的对象是Symfony\Component\HttpFoundation\File\UploadedFile类的一个实例，它扩展了PHP SplFileInfo类，提供了多种与文件交互的方法
So you can use this method: getClientOriginalName()
所以你可以使用这个方法： getClientOriginalName()
$request->file('input_pdf')->getClientOriginalName();
Would return the file name.
将返回文件名。
You can do this to check if the file exists before calling any methods on it:
您可以这样做以在调用文件的任何方法之前检查文件是否存在：
if ($request->hasFile('input_pdf')) {
return $request->file('input_pdf')->getClientOriginalName();
} else {
return 'no file!'
}
- To solve the issue of
dd($request->file('input_pdf'))returningnullcheck you are using the correct name for the file. You can trydd($request)and you will see if there are any files in it. You can check the file name when reviewing the dump of theRequestobject.
- 为了解决
dd($request->file('input_pdf'))返回null支票的问题，您使用了正确的文件名称。你可以试试dd($request)，看看里面有没有文件。您可以在查看Request对象的转储时检查文件名。

I think you forget to add
我想你忘了添加
enctype="multipart/form-data"
In your form. Or if you used laravel HTML service provider use
以你的形式。或者，如果您使用 laravel HTML 服务提供程序，请使用
{!! Form::open(array('files' => true)) !!}
