Laravel 5.2 MethodNotAllowedHttpException 无法发布数据

Question

我似乎无法在/cars/{id?}/modify 中发布数据

错误:

in RouteCollection.php line 219 at RouteCollection->methodNotAllowed(array('POST')) in RouteCollection.php line 206
at RouteCollection->getRouteForMethods(object(Request), array('POST')) in RouteCollection.php line 158

路线:

Route::get('/', 'PagesController@home');
Route::get('/about', 'PagesController@about');
Route::get('/contact', 'PagesController@contact');
Route::get('/cars', 'CarsController@index');

Route::get('/cars/{id?}/edit', 'CarsController@edit');
Route::post('/cars/{id?}/modify', 'CarsController@update');

Route::get('/cars/add', 'CarsController@add');
Route::post('/cars/add', 'CarsController@store');

Route::get('/cars/{id?}/delete','CarsController@destroy');

html:

    <form class="form-horizontal" method="post" action="/cars/{{ $car->id }}/modify">

Answer 1

laravel 中没有更新方法/路由之类的东西。对于编辑，您应该使用 PUT。

---

您可以通过改变两件事来解决您的问题:

您的路由方法

Route::post('/cars/{id?}/modify', 'CarsController@update');

到

Route::put('/cars/{id?}/modify', 'CarsController@update');

在你的表单中

<input name="_method" type="hidden" value="UPDATE">

到

<input name="_method" type="hidden" value="PUT">
