我有这个编辑表单，后退按钮不起作用，所以当我点击后退按钮时显示此错误，
这是我的createOffice的后退按钮我尝试将它应用到我的EditOffice后台按钮并且它不起作用：
<a href="{{ route('building', ['id' => $id] ) }}" class="btn btn-default">Back</a>
另外，如何点击UpdateOffice按钮，返回到办公室列表的页面，我使用return redirect（） - ＆gt; back（）;它保留在编辑表单页面中..是什么代码？
以下是代码
OfficeController.php
public function index()
{
$search = \Request::get('search');
$offices = Office::where('name','like','%'.$search.'%')->get();
return view('search')->with('offices', $offices)->with('search', $search);
}
/**

{
return view('createoffice')->with('id', $id);
}

public function store(Request $request, $id)
{
$office = new Office();
$office->name =$request->officename;
$office->floor = $request->floor;
$office->building_id = $id;
$office->save();
\Session::flash('building_flash', 'Created successfully!');
return redirect()->back();
}
/**

答案 0 :(得分：0)
我能看到的主要问题是你的路线定义和带有嵌套路线的参数传递。例如，让我们采取编辑办公室路线;
Route::get('building/{id}/offices/edit', 'OfficeController@edit')->name('editofficeform');
这实际上是一个嵌套路由，根据定义应该期待两个参数; （1）您正在编辑的建筑物的building_id，您指定为{id}（2）您还应该传递office_id，这将是该特定办公室的ID你想编辑。
正确的路线定义应该是这样的;
Route::get('building/{id}/offices/{office_id}/edit', 'OfficeController@edit')->name('editofficeform');
当你指定这样的编辑链接时，然后在building.blade.php上;
<a href="{{route('editofficeform', $office->id)}}" class="btn btn-success btn-sm">Edit</a>
应该改为这个;
<a href="{{route('editofficeform', ['id'=>$building->id, 'office_id'=>$office->id])}}" class="btn btn-success btn-sm">Edit</a>
在这里，您将传递主建筑物ID和您可以使用的特定办公室ID，并可以跟踪您所在的建筑物页面。
在OfficeController.php的控制器端，您可以将edit()操作更改为此;
public function edit($id, $office_id)
{
$office = Office::find($office_id);
return view('editoffice')->withOffice($office)->with('id',$id);
}
现在您可以在办公室编辑表单上使用相同的后退按钮链接，它应该可以正常工作，并且可以带您回到实际的建筑页面。
<a href="{{ route('building', ['id' => $id] ) }}" class="btn btn-default">Back</a>
我希望这种解释有助于解决此类任何其他问题。
由于您遇到此类其他路线的问题。在editoffice.blade.php中，您可以像这样更新表单标记;
{!! Form::open(array('route' => ['editoffice', ["id"=>$id, "office_id"=>$office->id]], 'class' => 'form')) !!}
并在OfficeController.php更新您的update()方法以处理此附加参数;
public function update(Request $request, $id, $office_id)
{
$office = Office::find($office_id);
$office->name =$request->officename;
$office->floor = $request->floor;
$office->update();
\Session::flash('building_flash', 'Updated successfully!');
//return redirect()->back();
// You can replace this statement with the following to redirect the user to building page, rather than going back to edit form.
return redirect()->route('building', $id);
}
您可以在createoffice.blade.php中使用相同的类比，也可以在store()方法中使用相同的类比。当然，不会有任何office_id。
