laravel-7 - 如何在 Laravel 7 中获取 POST 的所有输入底部

Question

我在Laravel有这个表格：

<form method="post">
    {{csrf_field()}}

    <button type="submit" value="happy" id="happy" name="reaction" class="border-0 btn-submit">
        <img src="/assets/images/reactions/happy.png" />
    </button>

    <button type="submit" value="angry" id="angry" name="reaction" class="border-0 btn-submit">
        <img src="/assets/images/reactions/angry.png" />
    </button>
    <button type="submit" value="ill" id="ill" name="reaction" class="border-0 btn-submit">
        <img src="/assets/images/reactions/ill.png" />
    </button>
    <button type="submit" value="love" id="love" class="border-0 btn-submit">
        <img src="/assets/images/reactions/in-love.png" />
    </button>
    <button type="submit" value="quiet" id="quiet" class="border-0 btn-submit">
        <img src="/assets/images/reactions/quiet.png" />
    </button>
    <button type="submit" value="sad" id="sad" class="border-0 btn-submit">
        <img src="/assets/images/reactions/sad.png" />
    </button>
    <!-- <input type="text" name="studentName" id="studentName" class="form-control" placeholder="please type in your name"> -->

    <input type="hidden" value="{{$article->id}}" id="post_id">
    <input type="hidden" name="_token" value="{{csrf_token()}}">
</form>

在我进入控制器后，从帖子中获取所有数据不起作用：

$request->request->all(); //Get all post requests


switch ($request->request->input('reaction')) {
    case 'happy':
        return response()->json(['success' => "happy"]);
        break;

    case 'angry':
        return response()->json(['success' => "angry"]);
        break;

    case 'ill':
        return response()->json(['success' => "ill"]);
        break;
}

我正在一一尝试这些代码，但它没有给我结果，而只是给我一个结果：

return $request->all(); 
$request->request->get('my_param'); 
$request->request->post('my_param'); 
$request->request->input('my_param');

但是没有工作！我厌倦了尝试获取按钮值或输入值。

我相信你要找的是

$request->all()并不是$request->request->all()

值的键也将是您在name元素的属性中指定的内容，而value将是值。

    <button type="submit" value="happy" id="happy" name="reaction" class="border-0 btn-submit">
        <img src="/assets/images/reactions/happy.png" />
    </button>


var_dump($request->all());

array() [
  'reaction' => 'happy'
]
