更改返回视图以在 laravel 搜索功能上返回路线

Question

我正在尝试更正我的控制器的 searchresult 函数的代码，所以我担心当我对搜索结果进行分页或进行表单验证时，我收到以下错误消息：此路由不支持 GET 方法。支持的方法：POST。 所以如果你能帮助我，我想将我的代码从返回视图更改为返回路线。 这是我的代码

路线：

Route::get('/post/searchpost', 'PostsController@index')->name('index');
Route::post('/post/search_result', 'PostsController@searchresult')->name('searchresult');

<div class="posts">
<h1>Posts</h1>
<div class="sreach">
    <form action="{{route('searchresult', app()->getLocale())}}" method="POST">
      {{ csrf_field()}}
      <div class="form-row">
        <div class="form-group col-md-2">

          @endforeach
          </select>

public function index()
    {
        $ctegories=  Category::all();
        return view('search')->with('posts', Post::all())->with('ctegories', $ctegories);
    }

    public function searchresult(Request $request)
    {
        $title= $request->title;
        $content= $request->content;
        $cat_id= $request->cat_id;

        $posts= Post::where('title', 'like', '%' . $title. '%')
        ->whereHas('category', function(Builder $query) use ($sujet_id){
            $query->where('id', $cat_id);
        })
        ->orderBy('created_at','desc')
        ->get();
        //for form dropdown categories
        $categories=  Category::all();

        if(count ($posts) > 0)
        {
            //this what i want to change from view to route with those parameters
            return view('searchresult')
            ->withDetails($posts)->withQuery($title)
            ->withCategories($categories);
        } else {
            return redirect()->route('index')->with('success','search not found');
        }
    }

因此，否则该功能可以完美运行，并且我得到了数据 我会感谢你的帮助谢谢你

您应该使用以下方法返回带参数的路由：

return \Redirect::route('nameOfRoute', ['param1'=>'value1','param2'=>'value2',...])->with('message', 'Search found!!!');
