我如何使用php将输入字段数组插入mysql

Question

我正在尝试将动态生成的输入字段的数组插入到我的数据库中。 问题是插入在插入过程中变得混乱。 当表格中的“某些”字段留空时，某些记录将插入错误的行中。 我在必须正确索引数组的地方加了红色。 我不知道该怎么做。 有更好的方法吗？ 还是有办法修复我的代码。

我到处寻找帮助，但没有找到任何帮助。 如果能从这里的专家那里得到一些帮助，我将不胜感激。

这是表格

                        <?php
                        while($row2=$coursefetch1->fetch()){


                          $iid = $row2['id'];
                          if($row2['type'] == 0){
                          echo '

                            <div class="tab-pane" id="'.$row2['id'].'">

                    ';
                  }

                          elseif($row2['type'] == 1){

                            echo '

                        }



                        ?>

这是处理表格的文件

                    <?php
                    require "head.php";


                    if (isset($_POST['submit'])) {

                      $answer_array1 = $_POST['yanswer1'];
                      $answer_array2 = $_POST['yanswer2'];
                      $answer_array3 = $_POST['yanswer3'];

                        $answer = $answer_array1[$i]."".$answer_array2[$i]."".$answer_array3[$i]."".$answer_array4[$i];

Answer 1

...

<input type="hidden" name="test_id" value="'.$row2['test_id'].'">
<input type="radio" name="yanswer1" value="a"><span> '.$row2['a'].' </span><br>
<input type="radio" name="yanswer2" value="b"><span> '.$row2['b'].' </span><br>
<input type="radio" name="yanswer3" value="c"><span> '.$row2['c'].' </span><br>

...在其他地方以此类推

编辑：

if (!empty($_POST['submit'])) {
