为什么答案没有正确存储在答案表中？ （数组问题）

Question

如果用户在会议中进行注册并且注册表会收集此数据：

 "name" => array:1 [▼
    1 => array:2 [▼
      1 => "Jake"    // name of the participant being registered in the registration_type_id 1
      2 => "John"    // name of the participant being registered in the registration_type_id 1
    ]
  ]
  "surname" => array:1 [▼
    1 => array:2 [▼
      1 => "W"  // surname off 1st participant being registered in the registration_type_id 1
      2 => "K" // surname off 2nd participant being registered in the registration_type_id 1
    ]
  ]
  "answer" => array:1 [▼
    1 => array:2 [▼
      1 => array:2 [▼ // answers of the 1st participant being registered in the registration_type_id 1
        1 => "answer1p1"
        2 => "answer2p1"
      ]
      2 => array:2 [▼ // answers of 2nd participant being registered in the registration_type_id 1
        1 => "answer1p2" 
        2 => "answer2p2"
      ]
    ]
  ]

然后有必要将参与者信息存储在参与者表中，并将与每个参与者关联的答案存储在答案表中。在参与者表中插入工作正常。

问题：在答案表中插入无法正常工作。在数据库中，它应该存储为：

id  |    participant_id    |    question_id    |    answer
159 |       153            |         1         |    answer1p1
161 |       153            |         2         |    answer2p1
163 |       154            |         1         |    answer1p2
165 |       154            |         2         |    answer2p2  

但是是这样存储的：

id  |    participant_id    |    question_id    |    answer
159 |       153            |         1         |     answer1p1
161 |       153            |         1         |    answer1p2
163 |       154            |          1        |    answer1p1
165 |       154            |          1        |    answer1p2  
160 |       153            |          2        |    answer2p1
162 |       153            |          2        |    answer2p2
164 |       154            |          2        |    answer2p1
166 |       154            |          2        |    answer2p2

要在参与者和答案表中插入的代码：

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

        if (isset($request['answer'][$key])) {
            foreach ($request->all()['answer'][$key] as $rID => $answers) {
                foreach ($answers as $question_id => $answer) {
                    $answer = Answer::create([
                        'question_id' => $question_id,
                        'participant_id' => $participant_result->id,
                        'answer' => $answer,
                    ]);
                }
            }
        }
    }
}

您总是为每个参与者添加所有答案 - 而您应该只添加他自己的答案。 您可能可以尝试这样的事情：

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

        if (isset($request['answer'][$reg_type][$nameKey])) 
        {
            foreach ($request['answer'][$reg_type][$nameKey] as $question_id => $answer) 
            {
                $answer = Answer::create([
                    'question_id' => $question_id,
                    'participant_id' => $participant_result->id,
                    'answer' => $answer,
                ]);
            }
        }
    }
}
