如果用户在进行会议注册，并选择数量“1”作为注册类型一般，“1”作为注册类型加，然后单击“下一步”并进入注册表。

在表格中，用户需要为每个参与者介绍姓名和姓氏，这两个字段对于每个正在注册的参与者始终是必需的。然后，注册类型 general 有 3 个与之关联的自定义问题，因此对于注册类型 general，用户还需要回答这 3 个自定义问题。用户在注册表单中回答的问题和答案如下：

Question                                  Answer
input text custom question                text answer
long text custom question:                long answer
checkbox custom question:                 check1answer

使用下面的注册表和上面的答案，显示中的参与者数组$request->all()如下所示。名称、姓氏、rtypes 已正确存储，但答案和 question_id 未正确存储在数组中：

  "participant" => array:2 [▼
    1 => array:15 [▼
      "name" => "John"
      "surname" => "W"
      0 => array:1 [▼
        "answer" => "text answer"
      ]
      1 => array:1 [▼
        "question_id" => "1"
      ]
      2 => array:1 [▼
        "answer" => "long answer"
      ]
      3 => array:1 [▼
        "question_id" => "2"
      ]
      4 => array:1 [▼
        "answer" => "check1answer"
      ]
      5 => array:1 [▼
        "question_id" => "3"
      ]
      "rtypes" => "1"
    ]
    2 => array:3 [▼
      "name" => "Jake"
      "surname" => "K"
      "rtypes" => "4"
    ]
  ]

使用此 foreach 插入参与者的数据存储方式和数据库中的答案在 $participant['answer'] 中显示“未定义索引：答案”：

foreach ($participants_list as $participant) {

    $name = $participant['name'];
    $surname = $participant['surname'];

    $participant_result = Participant::create([
         'name' => $name,
         'surname' => $surname,
         'registration_type_id' => $participant['rtypes']
    ]);

    Answer::create([
        'participant_id' => $participant_result->id,
        'answer' => $participant['answer'],
        'question_id' => $participant['question_id']
    ]);
}

您知道构建参与者数组以解决问题吗？那么是否可以将每个参与者的答案和 question_id 正确存储在答案表中？

The $participant[0]['answer'] shows "text answer".
The $participant[1]['answer'] shows "undefined index answer".
The $participant[2]['answer'] shows "long answer".
The $participant[3]['answer'] shows "undefined index answer".

我是初学者，但也许像这样的结构允许使用 foreach 存储在答案表中。数组的每个索引都存储与每个参与者相关的所有信息（姓名、姓氏、参与者正在注册的注册类型，以及是否有与注册类型相关的自定义问题也需要存储答案：

 "participant" => array:2 [▼
  1 => array:15 [▼
    "name" => "John"
    "surname" => "W"
    "answer" => [
      0  => "text answer"
      1  => "long answer"
      2  => "check1"
    ]
    "question_id" => [
      0 => "1"
      1 => "2"
      2 => "3"
    ]
    "rtypes" => "1"
  ]
  2 => array:3 [▼
    "name" => "Jake"
    "surname" => "K"
    "rtypes" => "4"
  ]
]

索引 2 中的参与者正在注册类型为“plus”的注册类型为 id 4，并且此注册类型没有任何关联的自定义问题。所以只需要收集姓名，姓氏和注册类型id。所以这对参与者 2 来说是可以的，因为没有自定义问题。

您需要以仅通过该代码获得所需格式的方式操作原始代码。

但是，如果您无法控制该代码，请尝试使用以下代码操作您当前的数组结构以使其成为所需的格式：-

$final  = array();
  foreach($array['participant'] as $key=>$val){

    $final['participant'][$key]['name'] = $val['name'];
    $final['participant'][$key]['surname'] = $val['surname'];
    $answer_array = array_column($val,'answer');
    $question_id_array = array_column($val,'question_id');
    if(is_array($answer_array) && count($answer_array) >0){
        $final['participant'][$key]['answer'] = $answer_array;
    }
    if(is_array($question_id_array) && count($question_id_array) >0){
        $final['participant'][$key]['question_id'] = $question_id_array;
    }
    $final['participant'][$key]['rtypes'] = $val['rtypes'];

  }

  print_r($final);
