对于我的网站，我需要一个包含PDF文件上传文件的表格，但是我是新手，并且不知道该怎么做。
这是我到目前为止所获得的，但是不断得到：
“函数
App\Http\Controllers\FileController::create()的参数太少，传递了0个参数，而恰好期望有1个参数”
控制器：
<?php
namespace App\Http\Controllers;
use App\User;
use App\Payment;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;
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 Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Kyslik\ColumnSortable\Sortable;
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',
];
}
模型付款：
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
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');
我希望有人能帮助我找出问题所在或更好的方法。预先谢谢你！
编辑：
您的回答对我有很大帮助，但是现在我面临另一个问题...
控制器现在看起来像这样：
<?php
namespace App\Http\Controllers;
use App\User;
use App\Payment;
use Illuminate\Support\Facades\Validator;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;
use Symfony\Component\HttpFoundation\File\UploadedFile;
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');
}
}
但是我收到一个新错误，这次是：
调用未定义的方法Illuminate \ Support \ Facades \ File :: hashName（）
任何想法？
答案 0 :(得分：1)
您的问题是方法create(array $data)中有一个参数，但是您仅使用{{ route('create') }}发布表单。在这里，您将通过此路由调用方法，而没有在定义时传递必需的参数。
基本上，表单发布方法可以接受请求的值
protected function create(Request $request)
因为您已经使用Request作为特征。
因此，您可以从表单中获取请求的字段值。而且您不必使用$request = app('request');，因为您已经在参数变量$request中使用了它。
如果您想知道
变量从前端传递（视图）
使用{{ route('update', $the_variable) }}到后端（路由）。
这样，您可以在路线的最后$the_variable之后加上/。
希望这会有所帮助。

路线：
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') }}"
