Laravel 7条件表格方法POST | PUT

Question

嗨，我正在使用Laravel 7，并尝试根据以下条件进行提交：

如果为isset($category) == true，则方法应为PUT如果isset($category) == false，则方法应更改为POST

为PUT]的更新方法>与响应302从POST更改为PUT正常工作。问题是如果我要根据给定条件通过POST方法提交，它说：

Symfony \ Component \ HttpKernel \ Exception \ MethodNotAllowedHttpException此路线不支持PUT方法。支持的方法：GET，HEAD，POST。

任何建议如何使用相同的形式？

这里是我的代码：

<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'）;

您还需要像下面一样调节@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>
