Laravel删除HTML表单的按钮

Question

我正在使用HTML表单,而不是Laravel Collective.

现在我已成功为我的CMS中的用户创建了一个CRUD,但有一件事困扰我:

如何在用户列表中设置"删除"按钮,而不是特定的编辑页面？

此外,当用户单击"删除"按钮以显示用于删除特定用户的确认弹出窗口时,这将是很好的.

所以,这是我的代码:

控制器:

/**
 * Remove the specified resource from storage.
 *
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function destroy($id)
{
    $user = User::findOrFail($id);
    $user->delete();

    return redirect('/admin/users'); 
}

用户列表页面:

@extends('layouts.backend')

@section('content')
  <h1>Users</h1>
  <a class="btn btn-primary" href="/admin/users/create">Create new user</a>
  <table class="table">
    <thead>
      <tr>
        <th>Id</th>
        <th>Name</th>
        <th>Email</th>
        <th>Role</th>
        <th>Status</th>
        <th>Created</th>
        <th>Updated</th>
        <th>Operations</th>
      </tr>

    </thead>
    <tbody>
      @if($users)
        @foreach($users as $user)
          <tr>
            <td>{{$user->id}}</td>
            <td>{{$user->name}}</td>
            <td>{{$user->email}}</td>
            <td>{{$user->role ? $user->role->name : 'User has no role'}}</td>
            <td>{{$user->status == 1 ? 'Active' : 'Not active'}}</td>
            <td>{{$user->created_at->diffForHumans()}}</td>
            <td>{{$user->updated_at->diffForHumans()}}</td>
            <td>
              <a href="/admin/users/{{$user->id}}/edit" class="btn btn-primary">Edit</a>
              <a class="btn btn-danger" href="">Delete</a> // HOW TO ACHIEVE THIS?
            </td>
          </tr>
        @endforeach
      @endif
    </tbody>
  </table>

@endsection

特定的编辑用户页面:

@extends('layouts.backend')

@section('content')
  <h1>Edit user</h1>
  <form method="POST" action="/admin/users/{{$user->id}}">
    {{ csrf_field() }}
    {{ method_field('PATCH') }}

    <div class="form-group">
      <label>Name:</label>
      <input type="text" name="name" class="form-control" value="{{$user->name}}">
    </div>

    <div class="form-group">
      <label>Email:</label>
      <input type="text" name="email" class="form-control" value="{{$user->email}}">
    </div>

    <div class="form-group">
      <label>Role:</label>
      <select name="role_id" class="form-control">
        @if($user->role_id == 1)
          <option value="1" selected>Administrator</option>
          <option value="2">Editor</option>
        @else
          <option value="1">Administrator</option>
          <option value="2" selected>Editor</option>
        @endif
      </select>
    </div>

    <div class="form-group">
      <label>Status:</label>
      <select name="status" class="form-control">
        @if($user->status == 1)
          <option value="1" selected>Active</option>
          <option value="0">Not active</option>
        @else
          <option value="1">Active</option>
          <option value="0" selected>Not active</option>
        @endif
      </select>
    </div>

    <div class="form-group">
      <label>Password</label>
      <input type="password" name="password" class="form-control" value="{{$user->password}}">
    </div>

    <div class="form-group">
      <input type="submit" name="submit" value="Update user" class="btn btn-primary">
    </div>
  </form>

  <form id="delete-form" method="POST" action="/admin/users/{{$user->id}}">
    {{ csrf_field() }}
    {{ method_field('DELETE') }}

    <div class="form-group">
      <input type="submit" class="btn btn-danger" value="Delete user">
    </div>
  </form>

  @include('inc.errors')
@endsection

路线:

Route::group(['middleware'=>'admin'], function(){
     Route::resource('admin/users', 'AdminUsersController');

     Route::get('/admin', function(){
       return view('admin.index');
     });
    // Route::resource('admin/posts', 'AdminPostsController');
});

从您发布的代码中可以看出这一点并不明显,但您的DELETE路线需要DELETE方法.正如它应该!

但是在您的列表中,您尝试使用GET方法访问它.

真的,你应该只重用编辑页面中的代码,这个代码DELETE已经伪造了.

像这样的东西:

...
<td>
    <a href="/admin/users/{{$user->id}}/edit" class="btn btn-primary">Edit</a>
    <form method="POST" action="/admin/users/{{$user->id}}">
        {{ csrf_field() }}
        {{ method_field('DELETE') }}

        <div class="form-group">
            <input type="submit" class="btn btn-danger delete-user" value="Delete user">
        </div>
    </form>
</td>
...

...
// Mayank Pandeyz's solution for confirmation customized for this implementation
<script>
    $('.delete-user').click(function(e){
        e.preventDefault() // Don't post the form, unless confirmed
        if (confirm('Are you sure?')) {
            // Post the form
            $(e.target).closest('form').submit() // Post the surrounding form
        }
    });
</script>
