英文:
Too few arguments to function App\Http\Controllers\EventController::edit(), 0 passed and exactly 1 expected
问题
"嗨，各位，请帮助我，我是 Laravel 新手，我不知道为什么会出现这个错误。
Symfony\Component\Debug\Exception\FatalThrowableError
App\Http\Controllers\EventController::edit() 函数的参数太少，期望传入 1 个参数，但传入了 0 个。
这是我的 EventController：
public function show(){$events = Event::all();return view('superadminpage.admin_event.admin_update_event')->with('events', $events);}/*** Show the form for editing the specified resource.** @param int $id* @return \Illuminate\Http\Response*/public function edit($id){$events = Event::find($id);return view('superadminpage.admin_event.admin_editform', compact('events', 'id'));}/*** Update the specified resource in storage.** @param \Illuminate\Http\Request $request* @param int $id* @return \Illuminate\Http\Response*/public function update(Request $request, $id){$this->validate($request,['title' => 'required','color' => 'required','start_date' => 'required','end_date' => 'required',]);$events = Event::find($id);$events->title = $request->input('title');$events->color = $request->input('color');$events->start_date = $request->input('start_date');$events->end_date = $request->input('end_date');$events->save();return redirect('admin_calendar')->with('success', '已添加');}
这是我的路由：
Route::get('/admin_update_event', 'EventController@show');Route::get('/admin_editform', 'EventController@edit');
这是我的 admin_update_event.blade.php：
@foreach ($events as $event)<tbody><tr><td>{{ $event->id}}</td><td>{{ $event->title}}</td><td>{{ $event->color}}</td><td>{{ $event->start_date}}</td><td>{{ $event->end_date}}</td><th> <a href="{{ route('edit',['id' => $event->id, 'event' => 1]) }}">编辑 </a></th></tr></tbody>@endforeach
这是我的 admin_editform.blade.php：
<form method="POST" action="{{action('EventController@update')}}">{{csrf_field() }}<div class="container"><div class="jumnbotron"><h1> 更新事件 </h1><br><input type="hidden" name="_method" value="UPDATE" /><div class="form-group"><label for="">输入事件的名称</label><input type="text" class="form-control" name="title" placeholder="输入名称" value="{{ $events->title}}"></div><div class="form-group"><label for="">选择颜色</label><input type="color" class="form-control" name="color" placeholder="选择颜色" value="{{ $events->color}}"></div><div class="form-group"><label for="">输入事件的开始日期</label><input type="datetime-local" class="form-control" name="start_date" class="date" placeholder="输入开始日期" value="{{ $events->start_date}}"></div><div class="form-group"><label for="">输入事件的结束日期</label><input type="datetime-local" class="form-control" name="end_date" class="date" placeholder="输入结束日期" value="{{ $events->end_date}}"></div>{{ method_field('PUT') }}<input type="submit" name="submit" class="btn btn-primary" value="添加事件数据"/></div></div></form>

问题出在你的 "edit" 路由没有参数，而 edit() 方法需要一个 $id 参数。尝试这样做：
Route::get('/admin_editform/{id}', 'EventController@edit');
英文:
The issue is your "edit" route having no parameters and the edit() method expects a $id parameter. Try this:
Route::get('/admin_editform/{id}', 'EventController@edit');

Route::get('/admin_editform/{id}', 'EventController@edit');
