EditForm后退按钮和如何在Laravel中返回重定向
EditForm后退按钮和如何在Laravel中返回重定向
提问于 2018-01-11 14:24:47
我有这个编辑表单，但后退按钮不起作用，所以当我单击后退按钮时，它会显示这个错误，
这是我的createOffice的后退按钮，我试着将它应用于我的EditOffice后退按钮，但它不起作用：
<a href="{{ route('building', ['id' => $id] ) }}" class="btn btn-default">Back</a>另外，如何使UpdateOffice按钮在单击时返回到我正在使用的return redirect()->back()的办公室列表页面，并且它停留在编辑表单页面中。正确的代码是什么？
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();
}
}PageController.php
class PageController extends Controller
{
public function buildings(){
$buildings = Building::paginate(10);
return view('buildings')->with('buildings', $buildings);

我能看到的主要问题是您的路由定义和使用嵌套路由传递参数。例如，让我们以编辑办公路由为例；
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，它应该有两个参数；(1)您正在编辑的大楼的building_id，您已经指定为{id} (2)您还应该传递office_id，这将是您想要编辑的特定办公室的id。
正确的路由定义应该是这样的；
Route::get('building/{id}/offices/{office_id}/edit', 'OfficeController@edit')->name('editofficeform');然后在building.blade.php上，当您像这样指定编辑链接时；
<a href="{{route('editofficeform', $office->id)}}" class="btn btn-success btn-sm">Edit</a>应该改成这样；
<a href="{{route('editofficeform', ['id'=>$building->id, 'office_id'=>$office->id])}}" class="btn btn-success btn-sm">Edit</a>在这里，您将传递主建筑id和特定的办公室id，您可以随心所欲地使用它们，并且可以跟踪您所在的建筑页面。
在OfficeController.php的控制器端，你可以把你的edit()动作改成这样；
public function edit($id, $office_id)
{
$office = Office::find($office_id);
return view('editoffice')->withOffice($office)->with('id',$id);
}现在，您可以在office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，并将您带回实际的构建页面。
<a href="{{ route('building', ['id' => $id] ) }}" class="btn btn-default">Back</a>我希望这个解释也能帮助解决其他类似的问题。
更新
因为您一直在使用此类型的其他路由时遇到问题。在editoffice.blade.php中，你可以像这样更新表单标签；
{!! Form::open(array('route' => ['editoffice', ["id"=>$id, "office_id"=>$office->id]], 'class' => 'form')) !!}并在OfficeController.php中更新您的update()方法以处理这个附加参数；
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);
}可以在createoffice.blade.php中使用相同的类比，在store()方法中也可以使用类似的类比。当然--不会有任何office_id。
