Laravel 9对于此路线不支持PUT方法。支持的方法：获取，头

Question

我只是在尝试更新数据时遇到错误。我正在使用帖子方法而不是推动。我尝试添加@method（'put'），但这也没有用。

创建新类别的工作正常工作，但是当我尝试编辑某些内容时，它会引发错误。我也试图使用路线:: put，但这无效。

我的类别controller.php

Answer 1

我将对您的代码进行这些修改：
edit.blade：

 <form action="/admin/category/update/{{$data->id}}" method="POST">
 @csrf
 @method('PUT')
 .........

路线：

Route::put('/admin/category/update/{id}', [AdminCategoryController::class,'update'] )->name('admin_category_update');

检查是否有效。

还有一件事：如果您正确创建 /a>，您的更新函数看起来像这样：

public function update(Request $request, Category $category, $id)
{
    //
    $category->parent_id = 1;
    $category->title = $request->title;
    $category->keywords = $request->keywords;
    $category->description = $request->description;
    $category->status = $request->status;
    $category->save();
    return redirect('admin/category');
}

那是因为您已经在那里拥有模型：public函数更新（请求$请求，**类别$类别**，$ id）
