Laravel:使用下拉列表显示数据

Question

我正在实现一个下拉菜单列表来显示我系统中的酒店列表。我目前有以下代码，当我点击提交时，什么也没有发生(没有显示数据)。

有谁知道我按下提交后如何潜在地显示数据。我相信我的 Controller 中需要代码。

SEARCH.BLADE.PHP

<form action="/search" method="POST" role="search">
   <div class="form-group">
    <select name="country" id="country" class="form-control input-lg dynamic" data-dependent="state">
 @foreach($posts as $post)
  <option value="{{$post->distance}}">{{$post->distance}} </option>
 @endforeach

   <br/>
   <div class="form-group">
    <select name="state" id="state" class="form-control input-lg dynamic" data-dependent="city">
    </select>
   </div>
   <br />
   <div class="form-group">
    <select name="city" id="city" class="form-control input-lg">
    @foreach($posts as $post)
  <option value="{{$post->title}}">{{$post->title}} </option>
 @endforeach
</div>
    </select>
   </div>
  </div>
  {{Form::Submit('submit', ['class' => 'btn btn-primary'])}}
 </body>

SearchController.php

class SearchController extends Controller { 
   public function index()
   {
     $posts = Post::all();
     return view('Pages.search')->with('posts', $posts);
   }

我没有太多的搜索 Controller ，但我相信我需要一些代码来显示数据。

用这个

<form action="/search" method="POST" role="search">

<div class="form-group">

<select name="country" id="country" class="form-control input-lg dynamic" data-dependent="state">

@foreach($posts as $post)
   <option value="{{$post->id}}">{{$post->title}} </option>
@endforeach

</select>
</div>

<div class="form-group">

<select name="city" id="city" class="form-control input-lg">

@foreach($posts as $post)
  <option value="{{$post->id}}">{{$post->title}} </option>
@endforeach

</select>
</div>

<div class="form-group">

<button type="submit" class="btn btn-adminsqure pull-right submitbutton"> Submit</button>

</div>

还要更改您的 Controller

class SearchController extends Controller { 

  public function index()
  {
    $posts = Post::get();
    return view('Pages.search', compact('posts'));
  }
