对于我的网站，我需要一个表格，其中包括PDF文件上传的文件，但我是新手，并且真的不知道该怎么做。
这是我到目前为止得到的，但是继续：
"太少的参数无法函数
AppHttpControllersFileController::create()，0通过，正是1个预期的1>"
控制器：
<?php
namespace AppHttpControllers;
use AppUser;
use AppPayment;
use IlluminateHttpRequest;
use IlluminateSupportFacadesStorage;
class FileController extends Controller
{
public function index(){
$users = User::all();
return view('fileupload.create', compact('users'));
}
protected function create(array $data)
{
$request = app('request');
if($request->hasfile('file')){
$file = $request->file('file');
$filename = $file['filename']->getClientOriginalExtension();
Storage::make($file)->save( public_path('/storage/loonstrookjes/' . $filename) );
dd($filename);
}
return Payment::create([
'file_name' => $filename,
'file_path' => '/storage/loonstrookjes/',
'user_id' => $data['employee'],
]);
return route('fileupload.create');
}
}
模型用户：
<?php
namespace App;
use IlluminateNotificationsNotifiable;
use IlluminateContractsAuthMustVerifyEmail;
use IlluminateFoundationAuthUser as Authenticatable;
use KyslikColumnSortableSortable;
class User extends Authenticatable
{
use Notifiable;
use Sortable;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $table = 'users';
protected $fillable = [
'username', 'first_name', 'last_name', 'email', 'password',
];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'password', 'remember_token',
];
/**
* The attributes that should be cast to native types.
*
* @var array
*/
protected $casts = [
'email_verified_at' => 'datetime',
];
}
型号付款：
<?php
namespace App;
use IlluminateDatabaseEloquentModel;
class Payment extends Model
{
protected $table = 'payment_list';
protected $fillable = [
'user_id', 'file_name', 'file_path'
];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'id', 'file_name', 'file_path'
];
}

这些是我的路线：
Route::get('/create', 'FileController@index')->name('create');
Route::post('/create', 'FileController@create');
我希望有人可以帮助我找出做出了什么问题或更好的方法。预先感谢您！
编辑：
您的答案对我有很大帮助，但是现在我正面临另一个问题...
控制器现在看起来像这样：
<?php
namespace AppHttpControllers;
use AppUser;
use AppPayment;
use IlluminateSupportFacadesValidator;
use IlluminateHttpRequest;
use IlluminateSupportFacadesStorage;
use SymfonyComponentHttpFoundationFileUploadedFile;
UploadedFile::getMaxFilesize();
class FileController extends Controller
{
public function index(){
$users = User::all();
return view('fileupload.create', compact('users'));
}
protected function validator(array $data)
{
return Validator::make($data, [
'filename' => ['required', 'string', 'max:255'],
'file' => ['required', 'file'],
'user_id' => ['required'],
]);
}
protected function create(Request $request)
{
$request = app('request');
if($request->hasfile('file')){
$file = $request->file('file');
$filename = $request->input('filename');
$file = $filename . '.' . $file->getClientOriginalExtension();
$file_path = storage_path('/loonstrookjes');
Storage::disk('local')->putFile($file_path, new File($request->file), $file);
//$path = $request->file('file')->store( storage_path('/storage/loonstrookjes/'));
//$path = Storage::putFile(storage_path('/loonstrookjes/'), $filename);
//dd($upload);
//return $put;
}
return Payment::create([
'file_name' => $filename,
'file_path' => '/storage/loonstrookjes/',
'user_id' => $request['user'],
]);
return route('fileupload.create');
}
}
但是我遇到了一个新错误，这一次是：
致电未定义的方法照明 support facades file :: hashname（）
任何想法??
您的问题是您的方法create(array $data)中有一个参数，但是您仅使用{{ route('create') }}发布表单。在这里，您是通过此路线调用该方法的情况，而无需传递所需的参数。
基本上，表单邮政方法可以接受此
的请求值 protected function create(Request $request)
因为您已经将Request用作特质。
因此，您可以从表格中获取所需的字段值。而且您不必使用$request = app('request');，因为您已经在参数变量$request上已有它。
如果您想知道
变量从前端传递（视图）使用{{ route('update', $the_variable) }}到后端（路线）。
这样，您可以在路线的最后一个/之后拥有$the_variable。
希望这会有所帮助。
路由：
Route::resource('File','FileController');
控制器更改：
public function store(Request $request)
{
if($request->hasfile('file')){
$file = $request->file('file');
$filename = $file['filename']->getClientOriginalExtension();
Storage::make($file)->save( public_path('/storage/loonstrookjes/' . $filename) );
}
return Payment::create([
'file_name' => $filename,
'file_path' => '/storage/loonstrookjes/',
'user_id' => $request->type
]);
return route('fileupload.create');
}
}
查看更改：
form action="{{ route('File.store') }}"
