在 Laravel foreach 循环中访问 JSON 数组

Question

我有一个函数 returns 我需要在视图中操作的数据。数据是根据关系从各种表链接而来的：

函数：

$auditResults = Audit::where('audit_id', $id)
   ->with('question', 'question.auditQuestion')
   ->get();

查看：

@foreach($auditResults as $answer)
    <p>{{$answer}}</p>
@endforeach

$answer 的输出：

{  
   "id":1,
   "audit_id":1,
   "audit_questions_details_id":2,
   "question":{  
      "id":2,
      "audit_question_id":2,
      "question_number":1,
      "comment":1,
      "header":0,
      "created_at":"2017-03-27 12:16:50",
      "updated_at":"2017-03-27 12:16:50",
      "audit_question":{  
         "id":2,
         "audit_detail_id":1,
         "question":"THIS IS WHAT I WOULD LIKE TO OUTPUT",
         "created_at":"2017-03-27 12:16:50",
         "updated_at":"2017-03-27 12:16:50"
      }
   },
   "score":null,
   "comment":null,
   "created_at":null,
   "updated_at":null
}

在foreach循环中，如何输出每个结果的question参数？

非常感谢。

Answer 1

这样做：

{{ $answer->question->comment }}

Answer 2

<p>{{$answer->question->audit_question->question}}</p>

获取题号

<p>{{$answer->question->question_number}}</p>

希望对您有所帮助

Answer 3

如果$answer真的是一个JSON(string)，那么你必须先解码它：

@foreach($auditResults as $answer)
    <?php $answer = json_decode($answer) ?>
    <!-- Now you have access to an PHP StdObject with your data -->
    <p>{{$answer->question}}</p>
@endforeach
