如何从数组中获取每个 question_id 和答案？

Question

如果用户在会议中进行注册，并且正在注册 1 名 id 为“1”的注册类型的参与者 (Jake K)，以及 1 名 id 为“4”的注册类型的参与者 (John W)，带有表单数据的请求有这 3 个数组：

"name" => array:2 [▼
  1 => array:1 [▼
    1 => "Jake"
  ]
  4 => array:1 [▼
    1 => "John"
  ]
]
"surname" => array:2 [▼
  1 => array:1 [▼
    1 => "K"
  ]
  4 => array:1 [▼
    1 => "W"
  ]
]
"answer" => array:1 [▼
  1 => array:1 [▼   
    1 => array:2 [▼   // answers answered for the registration_type_id 1
      1 => "answer1"
      2 => "answer2"
    ]
  ]
]

必须使用该数组的信息插入participants 和answers 表中。它在participants 表中正确插入，但对于answers 表不起作用：

 foreach ($request->all()['name'] as $key => $nameArray) {
        foreach ($nameArray as $nameKey => $name) {
            // this is working
            $participant_result = Participant::create([
                'name'                 => $name,
                'surname'              => $request['surname'][$key][$nameKey],
                'registration_id' => $registration->id,
                'registration_type_id' => $key
            ]);


            // save answer to Database if exist
            // this is not working
            $answer = Answer::create([
                'question_id' => $request['answer'][$key], // the issue is here
                'participant_id' => $participant_result->id,
                'answer' => $request['answer'][$key][$nameKey], // and here
            ]);
        }
    }

问题是因为需要在answers 表的question_id 和answer 列中插入。但是这个值没有从带有“$request['answer'][$key]”和“$request['answer'][$key][$nameKey]”的数组中正确返回。

你知道如何正确地从数组中获取问题 id 和答案吗？

在上述数组示例中，“answer1”的问题 id 为 1，“answer2”的 id 为 2。

  "answer" => array:1 [▼
    1 => array:1 [▼
      1 => array:2 [▼
        1 => "answer1"
        2 => "answer2"
      ]
    ]

Answer 1

首先：在循环中你有多个名字，但答案只有一个键（1）。在第二次运行时，您有 $key == 4，但在 $request['answer'] 中没有这个。也许在第一个循环内你应该有两个循环？一个用于注册参与者，一个用于注册答案？如果两者都注册了答案，则使用$participantResult 构建数组，并为每个答案注册count($participantResult) 答案：O 如果没有，请仅记住第一个注册参与者的 ID 并保存答案。

请告诉我$request['answer'] 是如何工作的？什么是$request['answer'][1]，什么是$request['answer'][1][1]？

其次，$request['answer'][$key][$nameKey] 在这种情况下是两个元素的数组。如果 Answer::create 知道 - 没问题 ;)

这是正确的解决方案吗？

<?php
$aPID = [];

foreach ($request->all()['name'] as $key => $nameArray) {
    foreach ($nameArray as $nameKey => $name) {
        $aPID[$key] = Participant::create([
            'name'                 => $name,
            'surname'              => $request['surname'][$key][$nameKey],
            'registration_id' => $registration->id,
            'registration_type_id' => $key
        ]);
    }
}

foreach($request['answer'] as $pid => $answersArray) {
    foreach($answersArray as $questionId => $answer) {
        $answer = Answer::create([
            'question_id' => $questionId,
            'participant_id' => $aPID[$pid],
            'answer' => $answer,
        ]);
    }
}
