Question

我有这个编辑表单，后退按钮不起作用。因此，当我单击后退按钮时，它会显示此错误

尝试获取非对象的属性“名称”（查看：C：\ xampp \ htdocs \ Eguide \ resources \ views \ building.blade.php）

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按钮返回办公室列表的页面？

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);

  }

/**
 * Show the form for creating a new resource.
 *
 * @return \Illuminate\Http\Response
 */

public function create($id)
{

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

/**
 * Store a newly created resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
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();


}

/**
 * Display the specified resource.
 *
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function show($id)
{
    $office = Office::find($id);
    return view('office')->withOffice($office);
}

/**
 * Show the form for editing the specified resource.
 *
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function edit($id)
{
    $office = Office::find($id);
    return view('editoffice')->withOffice($office)->with('id',$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)
{
    $office = Office::find($id);
    $office->name =$request->officename;
    $office->floor = $request->floor;
    $office->update();

      \Session::flash('building_flash', 'Updated successfully!');
return redirect()->back();

}

/**
 * Remove the specified resource from storage.
 *
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function destroy($id)
{
        $office = Office::find($id);
        $office->delete();
\Session::flash('building_flash_delete', 'Deleted successfully!');
        return redirect()->back();

    }
