Question

我有一个模板，该模板显示两个问题，供3个（三个）客户回答。如下面的响应所示，它重复了问题以显示每个客户的答案。

但是我想拥有的是，将类似的答案与它们的数量归为一组。我该怎么办？感谢您的帮助。

模板问题

1. How would you describe our products and services?

2. Overall, how satisfied or dissatisfied are your with our company?

现在，当客户回答问题时，它在我的视图中显示为

Answer 1

在您的Question模型中引入新功能

public function count_answers() {    
    return $this—>select(‘answers’, DB::raw('count(*) as counter'))->answers()->groupBy(‘answers’)->get();  
}

编辑视图

 <table class="bordered striped">
  <thead>
    <tr>
        <th data-field="id">Question</th>
        <th  data-field="ans">Answer(s)</th>
    </tr>
  </thead>

  <tbody>
    @forelse ($survey->questions as $item)
    <tr>
      <td width="30%">{{ $item->title }}</td>
<td  width="40%" >
