使用laravel对上传的文件进行验证

Question

如何在文件中添加验证角色，在这个例子中:

public function store( Product $product, Request $request)
{
$this->validate($request, [
'info' => ['required'],
'min' =>['required'],
'max' => ['required'],
'file' => ['nullable', 'mimes:jpg,jpeg,png,PNG,doc,docx,pdf,xsl,xlsx'],
]);
//store
if($request->hasFile('file')) {
$dest_path = 'public/orders/files';
$order_file = $request->file('file');
$file_name = time().'.'.$order_file->getClientOriginalName();
$order_file->storeAs($dest_path, $file_name);
try {
Order::create([
'info' => $request->info,
'min' => $request->min,
'max' => $request->max,
'file' => $file_name,
'product_id' => $product->id,
'user_id' => auth()->id(),
'owner_id' => $product->user->id
])->save();

在上面的方法中它不起作用…

，这是。blade文件:

<form action="{{route('order.store', [$product->id])}}" method="post"
enctype="multipart/form-data" class="">
@csrf
<div class="px-4 py-5 sm:p-6 items-center justify-center mb-5">

placeholder="write any information about your order"></textarea>
@error('info')
<p class="text-sm text-red-600">{{ $message }}</p>

</div>

您必须检查两件事:

1. 您的表单有enctype="multipart/form-data"吗?
2. 检查文件字段名。是file吗?
