php - 拉维尔 : $request->hasFile() is not working

Question

我有一个表格，可以得到 title , description和一个 image .当我 dd($requests->all()); , 它返回以下正确的。

array:4 [
  "projectTitle" => "asd"
  "project_description" => "asd"
  "project_image" => "15940723_1336567063030425_9215184436331587115_n.jpg"
  "_token" => "eUj27iioySvIgut5Afu0ZHMgeVrO99a9e1o7Tw0w"
]

我将这些值存储为:

$project = new Portfolio;
$project->freelancer_id = Auth::user()->id;
$project->title = $request->get('projectTitle');
$project->description = $request->get('project_description');

if($request->hasFile('project_image')){
   $project_image = $request->file('project_image');
   $filename = time() . '.' . $project_image->getClientOriginalExtension();
   Image::make($project_image)->resize(197, 137)->save( public_path('/uploads/portfolios/' . $filename ) );
   $project->img = $filename;
}

$project->save();

但是 img数据库表字段为空。

if($request->hasFile('project_image'))没有得到领域，

我还有表格，方法是 POST并且有 enctype="multipart/form-data"和一个文件我有 <input type="file" name="project_image" id="project_image"> .

我做错了什么？

Answer 1

如果您的代码中的一切都会正确，那么您可能会遗漏enctype，我在启动时也遗漏了它，

<form action="{{ route('store') }}" method="POST" enctype="multipart/form-data">

或者，如果您使用 Form Helper，该 enctype 很容易包含在 file=true 字段中。

{!! Form::open(['route' => ['store'], 'file' => true]) !!}
