Question

嘿我正在编写一个代码，当用户点击更新按钮时，它将转到另一个是doctorEdit的页面。我在我的网络文件中定义了路由，但它一次又一次地给出了未定义的错误路由。任何人都可以帮我解决我的问题。以下是我的代码。

路线代码：

 Route::resource('doctor/doctorEdit','DoctorController@edit');

控制器代码

  <?php

  namespace App\Http\Controllers;

  use Illuminate\Http\Request;
  use Illuminate\Support\Facades\DB;
  use App\Http\Controllers\Controller;

   class DoctorController extends Controller
      {
     public function edit()
      {
    return view('doctor.doctorEdit');
      }
    }

我的观看代码是

   <form class="row" method="POST" action="#" onsubmit = "return confirm('Are you sure?')">
                    <input type="hidden" name="_method" value="DELETE">
                    <input type="hidden" name="_token" value="{{ csrf_token() }}">
                    <a href="{{ route('doctor/doctorEdit', ['id' => $doctor->id]) }}" class="btn btn-warning col-sm-3 col-xs-5 btn-margin" style="width:100px; margin-left:20px;">
                    Update
                    </a>
                     <button type="submit" class="btn btn-danger col-sm-3 col-xs-5 btn-margin" style="width:100px; margin-left:20px;">
                      Delete
                    </button>
                </form>

请让我知道我做错了什么因为我是laravel的新人。

尝试将GET方法与命名路由一起使用。

您的路线文件

Route::get('doctor/doctorEdit','DoctorController@edit')->name('doctor.edit');

您的观看代码

<form class="row" method="POST" action="#" onsubmit = "return confirm('Are you sure?')">
                    <input type="hidden" name="_method" value="DELETE">
                    <input type="hidden" name="_token" value="{{ csrf_token() }}">
                    <a href="{{ route('doctor.edit', ['id' => $doctor->id]) }}" class="btn btn-warning col-sm-3 col-xs-5 btn-margin" style="width:100px; margin-left:20px;">
                    Update
                    </a>
                     <button type="submit" class="btn btn-danger col-sm-3 col-xs-5 btn-margin" style="width:100px; margin-left:20px;">
                      Delete
                    </button>
                </form>

您做错了，请查看Resource Controllers上的文档。

基本上，如果使用Route::resource()方法定义资源，则不能指定控制器操作，因为资源控制器应该提供兼容的REST方法。

因此，如果要创建REST资源控制器，则必须将路由指定为：

Route::resource('doctor', 'DoctorController');

所以你必须只指定你的控制器类名。

然后在您的控制器中，您必须指定所需的方法：

class DoctorController extends Controller 
{

    public function index()
    {
        // GET yourapp.com/doctor -> typically return all doctors
    }

    public function create()
    {
        // GET yourapp.com/doctor/create -> typically show doctor creation form
    }

    public function show()
    {
       // GET yourapp.com/doctor/{doctor_id} -> show a single doctor
    }

    public function store() 
    {
      // POST yourapp.com/doctor -> create a new doctor
    }

    public function edit()
    {
      // GET yourapp.com/doctor/{doctor_id}/edit -> show edit form view
      return view('doctor.doctorEdit');
    }

    public function update()
    {
       // PUT|PATCH yourapp.com/doctor/{doctor_id} -> update a doctor
    }

    public function destroy()
    {
       // DELETE yourapp.com/doctor/{doctor_id} -> delete a doctor
    }

}

如果您只想在没有REST逻辑的情况下公开edit表单，请使用Request::get()方法：

Request::get('doctor/doctorEdit', 'DoctorController@edit')->name('doctor.edit');

如果您要缓存路线，请记住使用artisan命令序列刷新它们

php artisan route:clear
php artisan route:cache

或更简洁 php artisan route:cache

Answer 3

您正在定义资源。正确的方法是：

Route::resource('doctor','DoctorController');

DELETE方法的名称为doctor.destroy，控制器方法为destroy

您的观看代码应为

        <form class="row" method="POST" action="{{ route('doctor.delete') }}" onsubmit = "return confirm('Are you sure?')">
                <input type="hidden" name="_method" value="DELETE">
                <input type="hidden" name="_token" value="{{ csrf_token() }}">
                <a href="{{ route('doctor.edit', ['id' => $doctor->id]) }}" class="btn btn-warning col-sm-3 col-xs-5 btn-margin" style="width:100px; margin-left:20px;">
                Update
                </a>
                 <button type="submit" class="btn btn-danger col-sm-3 col-xs-5 btn-margin" style="width:100px; margin-left:20px;">
                  Delete
                </button>
            </form>

路由未定义，即使我已定义它
