Laravel подтверждает удаление в предупреждении на мой взгляд

Question

Это должно быть простым заданием, я просто еще не совсем понимаю ларвел. У меня есть вид контроллеров и настройка моделей. Я хочу использовать мой маршрут users.destroy, чтобы удалить мою строку в БД. Но я хочу сделать это определенным образом. Я хочу, чтобы в моей зоне оповещений на моей странице отображалось оповещение с просьбой подтвердить удаление определенного пользователя. Я предполагаю, что мне нужно передать идентификатор пользователя в сеансе в оповещение, чтобы подтвердить мое удаление нажатием кнопки удаления. Нажмите кнопку 1, чтобы открыть оповещение в верхней части моей страницы, если я нажму подтвердить, что оно вызывает user.destroy.

Вид:

<div class="container">
  <div class="row justify-content-center">
    <div class="col-md-12">
      <div class="card">
        <div class="card-header">
          <h4>View All Users</h4>

          @if(session()->get('success'))
          <div class="alert alert-success">
            {{ session()->get('success') }}
          </div>
          @endif
          @if(session()->get('danger'))
          <div class="alert alert-danger">
            {{ session()->get('danger') }}
          </div>
          @endif
        </div>
        <div class="card-body">
          <div class="text-center my-2">
            <a href="{{ route('register') }}" class="btn btn-primary">New User</a>
          </div>
          <div>
            <table class="table table-striped table-bordered">
              <thead>
                <tr>
                  <th>ID</th>
                  <th>Name</th>
                  <th>Email</th>
                  <th>Username</th>
                  <th colspan="2">Actions</th>
                </tr>
              </thead>
              <tbody>
                @foreach($users as $user)
                <tr>
                  <th>{{$user->id}}</th>
                  <td>{{$user->name}}</td>
                  <td>{{$user->email}}</td>
                  <td>{{$user->username}}</td>
                  <td class="text-center">
                    <a href="{{ route('users.show', $user->id) }}" class="btn btn-primary mr-3">Show</a>
                    <a href="{{ route('users.edit', $user->id) }}" class="btn btn-info text-white ml-3">Edit</a>
                    <a href="#" class="btn btn-danger">Delete</a>
                  </td>
                </tr>
                @endforeach
              </tbody>
            </table>

Контроллер

public function destroy($id)
{
    User::find($id)->delete();
    return redirect()->route('users.index')->with('success','User Deleted');
}

Маршрут:

Route::resource('users', 'UserController');

Answer 1

Это просто пример. Я рассматриваю вашу модель как User.php

Если вы хотите иконку, просто добавьте шрифт awesome css

Откройте вашу User.php модельи вставьте следующий код

/**
    * @function     tableActionButtons
    * @author       Manojkiran <manojkiran10031998@gmail.com>
    * @param        string  $fullUrl
    * @param        integer  $id
    * @param        string  $titleValue
    * @param        array  $buttonActions
    * @usage        Generates the buttons
    * @version      1.0
    **/
    /*
    NOTE:

    if you want to show tooltip you need the JQUERY JS and tooltip Javascript

    if you are not well in JavaScript Just Use My Function toolTipScript()

                return  'only <code>group</code> and <code>dropdown</code> is Available ';
            }
        }
    }

Теперь добавьте это к User.php

use Illuminate\Support\HtmlString;

Теперь откройте свой список index.blade.php и внутри итерации цикла добавьте строку ниже

{{ App\User::tableActionButtons(url()->full(),$user->id,$user->name,['delete'],null,false) }}

Если вам нужно несколько кнопок, аргумент 4rt Принимает массив

{{ App\User::tableActionButtons(url()->full(),$user->id,$user->name,['show','edit,'delete],null,false) }}

Если у вас возникнут какие-либо проблемы, пожалуйста, прокомментируйте ниже

Надеюсь, это поможет

Всегда старайтесь использовать DELETE метод для удаления ресурса, который является наилучшим способом и практикой

        </div>
    </div>
</div>  
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<script type="text/javascript">
    $('.show_confirm').click(function(e) {
        if(!confirm('Are you sure you want to delete this?')) {
            e.preventDefault();
        }
    });
</script>

Если вы используете Laravel коллективный HTML , тогда вы можете заменитьэтот тег формы

Answer 3

Добавить ссылку для удаления записи

   <a href="{{ route('users.delete', $user->id) }}" class="btn btn-danger" onclick="return confirm('Are you sure you want to delete this item?');">Delete</a>

Answer 4

Вы можете просто использовать функцию onclick в своем теге, например

<a href="{{ route('users.delete', $user->id) }}" class="btn btn-danger" onclick="return confirm('Are you sure you want to delete this usere?');">Delete</a>
