Question

我正在使用Laravel 5.6.26。当我尝试通过将id发送给destroy（）来删除特定帖子时，它在刀片上显示了正确的id。但是当我在PostsController上dd（$ id）时，它显示了不同的id。为什么？谁能向我解释？谢谢！

home.blade.php

@foreach($posts as $post)

  <div class="jumbotron" style="background-color:#b3e0ff">

    <div class="btn-group float-right">
      <span  class="btn btn-default dropdown-toggle " data-toggle="dropdown">
         </span>

          <ul class="dropdown-menu" role="menu" id="{{$post->id}}">
            <li><a href="#">Edit</a></li>
            <li>


            <a href="#" onclick=" 
                var result = confirm('Are you sure you wish to delete this {{$post->id}}?');
                    if( result ){
                            event.preventDefault();
                            document.getElementById('delete-form').submit();

                    } "> Delete
            </a>

            <form id="delete-form" action="{{ route('posts.destroy',['$id'=> $post->id]) }}"  method="POST" style="display: none;">

                      <input type="hidden" name="_method" value="delete">
                      {{ csrf_field() }}

                       {{ method_field('DELETE') }}
            </form>


          </li>

          </ul>
    </div>@endforeach {{ $posts->links() }}

PostsController.php

public function destroy($id)
{
    //

    dd($id);

}

但是当我尝试将route参数修改为此时

route('posts.destroy',['$id'=> 5]) }}

我在PostsController上获得正确的dd 5。

web.php

Route::resource('posts', 'PostsController');

Answer 1

问题解决了。我没有获得正确的ID，只需修改此

delete-form

对此

delete-form_{{$post->id}}

Laravel。路由将不正确的参数传递给foreach循环中的destroy（）
