Laravel 资源路由未使用 {{method_field('PATCH')}} 在数据库中更新答案

【问题标题】：Laravel resource route is not updating in database using {{method_field('PATCH')}}Laravel 资源路由未使用 {{method_field('PATCH')}} 在数据库中更新
【发布时间】：2020-05-15 17:52:37
【问题描述】：

Laravel resource 当我点击更新按钮时，路由没有更新，但它在同一进程中存储。

我正在使用data-toggle="modal" 更新我的值，但它没有更新我的类别？

我的问题到底在哪里？我检查我的 id 是否正确传递，但它不会用于我的更新控制器功能。我在控制器的更新功能中使用dd($request->all()); 进行检查。

我的路线是

Route::resource('/mother-category', 'MotherCategoryController');

我的更新和存储功能是

public function store(Request $request)
    {
        $validator =Validator::make($request->all(), [
            'mother_name' => 'required',

        ]);

        if ($validator->fails()) {
            return redirect()->back()->withErrors($validator);
        }

        MotherCategory::insert([
            'mother_name'=>$request->mother_name
        ]);

        return redirect()->back()->with('message','Mother Category Created Successfully');
    }



    public function update(Request $request, MotherCategory $motherCategory)
    {

        $motherCategory->update([
            'mother_name' => $request->mother_name
        ]);

        return redirect()->back()->with('message','Mother Category Updated successfully');
    }

我的刀片文件是

@section('title', 'Add Mother Category')

@section('content')

【问题讨论】：

如果它没有达到你的更新方法，那么还会发生什么？ 404？
当我点击更新按钮时没有任何反应。
你能检查你的页面并显示呈现的 HTML 吗？那么您的表单似乎有问题。
是的，我检查并渲染了 HTML。
但是您能否将呈现的 html 添加到您的问题中 - 可能您的表单定义存在问题。

【讨论】：

可能你不明白我的问题。我没有任何编辑视图，它是data-toggle="modal"。我只使用数据切换，它不应该打开另一个页面。

【解决方案2】：

正如评论所述，问题是表单正在直接关闭，因为它可以在 html 中看到

<div class="modal-body">
  <form action="http://localhost:8000/mother-category/2" method="POST"></form>
    <input type="hidden" name="_token" value="F0fzi1ufy2sO9r8apQ6NTrDtDgfGqycpEiUvaMEG">
    <input type="hidden" name="_method" value="PUT">
    ...

由于刀片不直接关闭（见下文）

<form action="{{route('mother-category.update',$mc->id)}}" method="post">
  {{ csrf_field() }}
  ...

问题一定是你的html本身

快速谷歌将我发送到此：Laravel blade form closing issue

问题是您在表格中使用表格。您必须将其包装在 td 中或将其完全移出您的桌子。

希望这能解决问题

【解决方案3】：

将{{method_field('PATCH')}} 替换为{{method_field('PUT')}}

或者你可以使用刀片指令@method('PUT')

<form action="/foo/bar" method="POST">
    @method('PUT')

    ...
</form>

仍然无法正常工作，我认为主要问题是它不会更新功能。
