我想在Laravel中上传多个图像，错误显示文件名到刀片文件中。比如我想上传四个文件。其中两个是图像，另外两个是PDF文件，所以它应该阻止我这样做，因为我想只是图像上传，也会告诉我这两个PDF文件的名称是不允许的。但我得到了：
The uploads.0 must be an image.
The uploads.0 must be a file of type: jpeg, png, jpg, gif, svg.
The uploads.2 must be an image.
The uploads.2 must be a file of type: jpeg, png, jpg, gif, svg.因此，我希望用户必须知道，到哪个文件，他们犯了错误，因为有可能上传超过20个文件，所以如果我可以打印文件名，他们可以很容易地确定哪里是问题。此外，我不能得到这个错误被打印下来的输入;我在Blade文件中使用此代码时出现此错误，
@if (count($errors) > 0)
<div class="alert alert-danger">
<ul>
@foreach ($errors->all() as $error)
<li>{{ $error }}</li>
@endforeach
</ul>
</div>
@endif因此，我希望验证应该与文件名，它应该显示在输入文件下面，因为到我的其他输入字段显示。
到我的其他输入字段我已经显示了错误与此为所有错误
@if($errors->has('shipping_code'))
<div class="error text-danger fs-6 fw-400">{{ $errors->first('shipping_code') }}</div>
@endif进入我的控制器

你可以这样做你的验证：
您可以获取其他字段的错误，如您使用的方式：
但是对于上传，您可以使用。
如果未选择文件，则用于获取：
如果多个选定的文件有错误：
它也不会伤害你的
