Laravel 7 条件形式方法 POST |放

Question

您好，我正在使用 Laravel 7 并尝试根据以下条件提交：

如果isset($category) == true 那么方法应该是PUT
如果 isset($category) == false 则方法应更改为 POST

PUT 的更新方法适用于响应 302 从 POST 更改为 PUT。问题是我是否要根据给定条件通过 POST 方法 提交：

Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException
此路由不支持 PUT 方法。支持的方法：GET、HEAD、POST。

任何建议如何做到这一点，以相同的形式？

这是我的代码：

<form action="{{ isset($category) ? route('categories.update',$category->id) : route('categories.store') }}" method="POST">
    @csrf
    @method('PUT')
        <div class="form-group">
            <label for="name">Name</label>
            <input type="text" id="name" class="form-control" name="name" value="{{ isset($category) ? $category->name : '' }}">
        </div>

   <div class="form-group">
      <button class="btn btn-success">
        {{ isset($category) ? 'Update category' : 'Add category' }}
      </button>
   </div>
</form>

我正在使用 Route::resource('categories','CategoriesController');

您需要像下面这样调节@method('PUT')：

<form action="{{ isset($category) ? route('categories.update',$category->id) : route('categories.store') }}" method="POST">
    @csrf
    @if(isset($category))
       @method('PUT')
    @endif
        <div class="form-group">
            <label for="name">Name</label>
            <input type="text" id="name" class="form-control" name="name" value="{{ isset($category) ? $category->name : '' }}">
        </div>

   <div class="form-group">
      <button class="btn btn-success">
        {{ isset($category) ? 'Update category' : 'Add category' }}
      </button>
   </div>
</form>
