There is couple of method you can apply while you uploading some file(s) using laravel's. Here is the couple of them and most important to, in my thought.
当您使用 laravel 上传一些文件时，您可以应用几种方法。在我看来，这是其中最重要的几个。
$request->hasFile('file_name')
hasFilemethod to check user upload file or not.
hasFile检查用户上传文件与否的方法。
$request->file('file_name')->isValid()
isValidmethod take care to check file have no error.
isValid方法注意检查文件有没有错误。
After these checks, you have to get file properties and move to desired location. For these purposes.
在这些检查之后，您必须获取文件属性并移动到所需位置。为了这些目的。
$document = $request->file('file_name');
Get the document information object. So after that you can use further helper function provided my laravel FileUploader.
获取文档信息对象。所以在那之后你可以使用我的 laravel FileUploader 提供的进一步帮助函数。
$document->getRealPath();
$document->getClientOriginalName();
$document->getClientOriginalExtension();
$document->getSize();
$document->getMimeType();
and finally to move the uploaded file
最后移动上传的文件
$document->move($destinationPath);
$document->move($destinationPath, $fileName);
update
更新
However if you using slim to upload file, you have to use native php methods like globals Filesarray to get file and move_uploaded_file to move file and like so.
但是，如果您使用 slim 上传文件，则必须使用本机 php 方法，例如 globalsFiles数组来获取文件和 move_uploaded_file 来移动文件等等。
If you still have any question related to upload a file or file validation let me know.
如果您对上传文件或文件验证仍有任何疑问，请告诉我。
