Question

见下图。当我点击任何注册按钮时，最后一行被插入而不是我需要的行。

我需要的是：如果我点击注册，整个选定的行必须存储在另一个表中。

这里有什么不对？请帮帮我..

<table class="table table-striped jambo_table table-bordered"> <thead> <tr> <th width="75px">Semester:</th> <th width="110px">Subject Code:</th> <th>Subject Name:</th> <th width="110px">Exam Type:</th> <th  width="110px">Marks:</th> <th width="75px">Action:</th> </tr> </thead> <?php
    $view_users_query="select * from details WHERE regd_no='" .$_SESSION['regd_no']. "'";//select query for viewing users.
    $run=mysqli_query($dbcon,$view_users_query);//here run the sql query.
    while($row=mysqli_fetch_array($run))//while look to fetch the result and store in a array $row.
    {
        $slno=$row[0];
        $sem=$row[5];
        $subject_code=$row[9];
        $subject_name=$row[10];
    ?> <tr> 
    <td><input type="text" class="form-control" readonly="yes" name="sem1" id="sem1" value="<?php echo $sem;?>"></td> 
    <td><input type="text" class="form-control" readonly="yes" name="subject_code1" id="subject_code1" value="<?php echo $subject_code;  ?>"></td> 
    <td ><input type="text" class="form-control" readonly="yes" name="subject_name1" id="subject_name1" value="<?php echo $subject_name;  ?>"></td> 
    <td> <select class="form-control" id="etype" name="etype"> <option value="">Select-Exam-Type</option>

    <td> <input type="submit" name="register/<?php echo $subject_code?>" class="btn btn-success form-control" value="Register" > </td> 
    <!--btn btn-danger is a bootstrap button to show danger--> </tr>

$insert_user="insert into registered (regd_no,name,branch,batch,email,mobile,center,sem,subject_code,subject_name,date,etype,marks) VALUE ('$regn','$name','$branch','$batch','$email','$mobile','$center','$sem1','$subject_code1','$subject_name1','$date','$etype','$marks')";
   if(mysqli_query($dbcon,$insert_user))
{

我建议你查看你的if语句。它说：

如果行数大于0，则回显：

<script>alert('Subject Name $subject_name1 with Subject Code $subject_code1 is already registered')</script>

然后你在{}中有你的插入行，无处指向它是否在if语句或任何东西下。

如何在每一行上创建插入按钮？
