N.B: 我使用的是Laravel 7.x.
当你上传一个文件时，php会给它起一个临时的名字和位置(比如......)，直到你找到它为止。C:\xampp\tmp\phpE0A1.tmp)，直到你在某个地方找到它。
通常你保存在数据库中的是文件的位置和名称，一旦文件位于你的项目目录中
所以，先存储文件，然后把路径保存在数据库中。
public function store(Request $request)
{
$this->validate($request, [
'h4_title' => 'required',
'h2_title' => 'required',
'banner_paragraph' => 'required',
'banner_photo' => 'required|file'
]);
$path = $request->file('banner_photo')->store('public/image/banner_image');
$banner = new Banner([
'h4_title' => $request->get('h4_title'),
'h2_title' => $request->get('h2_title'),
'banner_paragraph' => $request->get('banner_paragraph'),
'banner_photo' => $path
]);
$banner->save();
return redirect()->back()->with('success', 'Data Added');
}
或者，既然你要把文件存储在... public/ 存储目录，您可以使用公共磁盘来存储文件。
$path = $request->file('banner_photo')->store(
'image/banner_image', 'public'
);
奖金:
您可以通过您的网址访问它。index.blade 表。
<table class="table table-striped table-hover">

@foreach($banners as $row)
<tr>
<td>{{$row->id}}</td>
<td>{{$row->h4_title}}</td>
<td>{{$row->h2_title}}</td>
<td>{{$row->banner_paragraph}}</td>
<td><img src="{{ asset( Storage::url($row->banner_photo) ) }}" /></td>

注: 此外，你应该 建立象征性联系 在 public/storage 这指的是 storage/app/public 目录。
