Question

一切正常，但是我想使用单选按钮值将$result['id'];插入数据库。

JavaScript：

<script>
    $(document).ready(function() {
        $('input[type="radio"]').change(function() {
            var stu_ans = $(this).val();
            var stu_id = "<?php echo $_GET['sid'];?>";
            var q_id = "<?php echo $result['id'];?>";
            $.ajax({
                url: "insert1.php",
                method: "POST",
                data: {
                    stu_ans: stu_ans,
                    stu_id: stu_id,
                    q_id: q_id
                },
                success: function(data) {
                    $('#result').html(data);
                }
            });
        });
    }); 
</script>

HTML：

<form  role="form" id='formid' method="post" action="result.php?s_id=<?php echo $_GET['sid'];?>">
  <?php
    $number_question = 1;
    $row = mysqli_query( $con, "select * from question where subject_id='$category' ORDER BY RAND()");
    $rowcount = mysqli_num_rows( $row );
    $remainder = $rowcount/$number_question;
    $i = 0;
    $j = 1; $k = 1;
    ?>
  <h4>Total Question:-<?php echo $rowcount;?></h4>
  <?php 
    while ( $result = mysqli_fetch_assoc($row) ) {
      if ( $i == 0) echo "<div class='cont' id='question_splitter_$j'>";
  ?>
  <div id='question<?php echo $k;?>' >
    <p class='questions' id="qname<?php echo $j;?>" style="font-size:20px;font-weight:bold;color:green"> (<?php echo $k?>).<?php echo $result['que'];?></p>

在代码中保留SQL注入和安全性内容...

更改

var stu_ans=$(this).val();

针对：

var stu_and =$("input[name='<name_of_radio>']:checked").val();

这是从选定的单选按钮获取值的方法。

然后请！！！看看安全问题。

希望此代码对您有所帮助！
