在 RouteCollection.php 行 219 中获取 MethodNotAllowedHttpException：在 laravel

Question

我收到上述错误。我试图在其他论坛上阅读有同样问题但没有运气。我的创建、存储和编辑工作正常。但是，在更新我的表单时，我收到了上述错误。有人可以帮我解决这个问题吗？谢谢

{!! Form::model($enrollment['method'=>'POST','route'=>['/enrollment',$enrollment->id],'class'=>'form-horizontal']) !!}

{!! Form::close() !!}

这是我的 EnrollmentController：

    public function update(EnrollmentRequest $request, $id)
{
    $enrollment = Enrollment::findOrFail($id);
    $enrollment->update($request->all());
    return redirect('/enrollment');
}

routes.php

// Authentication routes...
Route::get('auth/login', 'Auth\AuthController@getLogin');
Route::post('auth/login', 'Auth\AuthController@postLogin');
Route::get('auth/logout', 'Auth\AuthController@getLogout');

// Registration routes...
Route::get('auth/register', 'Auth\AuthController@getRegister');
Route::post('auth/register', 'Auth\AuthController@postRegister');

Route::resource('enrollment','EnrollmentController');

Answer 1

我认为问题是您的 HTML 有误。在您的第一个 "subject_code" 输入中，您有以下 HTML:

<select class="form-control" name="_method" value="PUT" id="subject_code">

您不小心将此输入命名为 _method，这是为 Laravel 方法欺骗保留的输入名称。即使您已将值指定为 "PUT"，这也不是 selects 的工作方式，并且该值最终会变成别的东西。这会阻止 Laravel 方法欺骗正常工作。由于方法欺骗不起作用，您正在向 enrollment/{id} 发送 POST 请求，并且该路由不允许 POST 请求。

您需要更正此输入，使其不被命名为“_method”：

<select class="form-control" name="subject_code" id="subject_code">

此外，您需要修正您的 Form::model() 语句。它需要带两个参数，第一个是模型，第二个是属性数组。在您的属性数组中，您需要 "method" 为 "PUT"（以便表单构建器自动创建隐藏的“_method”输入），并且您需要 [=28= 中的第一个元素] 数组是路由的名称，而不是 url。更新显示如下：

{!! Form::model($enrollment, ['method' => 'PUT', 'route' => ['enrollment.update', $enrollment->id], 'class' => 'form-horizontal']) !!}
