laravel请求文件返回null(添加了enctype)

Question

当我上传任何东西时，它都会返回null，但如果我试图在控制器中返回$_FILES，它会返回我上传的文件，我添加了enctype="multipart/form data"，但仍然没有运气

这是我的表格

<form action="{{url('add_attachments')}}" method="post" enctype="multipart/form-data">
@csrf @method('put')
<div class="row">
<div class="col-12">
<label class="small">Tambahkan lampiran</label>
<div class="form-group mb-1 upload">
<input type="file" name="lampiran[]" multiple accept="image/jpeg,image/gif,image/png,application/pdf" />
</div>
</div>
</div>
<div class="row">
<div class="col">
<button type="submit">Upload</button>
</div>
</div>
</form>

这是我的控制器

<?php
namespace AppHttpControllers;
use IlluminateHttpRequest;
class ProposalController extends Controller
{
public function add_attachment(Request $request, $id)
{
return $request->file('lampiran'); //return null
return $_FILES; //return {"lampiran":{"name":["7680cf333da548d4213fd5f574b66ffbdccba917.jpg"],"type":["image/jpeg"],"tmp_name":["/tmp/phpBIcJYs"],"error":[0],"size":[138198]}}
}
}

Answer 1

您的<input type="file" name="lampiran[]" multiple accept="image/jpeg,image/gif,image/png,application/pdf"/>是一个数组lampiran[]

试试这个

public function add_attachment(Request $request,$id)
{
return $request->file('lampiran.0');
}

或

public function add_attachment(Request $request,$id)
{
foreach($request->file('lampiran') as $image){
dd($image):
}
}
