获取ajax中行的值

Question

我在使用ajax获取表格行的值时遇到问题，到目前为止每次获取其值时，我都没有给予任何回报，这就是我得到它的方式。

select.php

      while($row = mysqli_fetch_array($result))  
  {  
       $output .= '  
            <tr>  
                 <td>'.$row["wmID"].'</td>  
                 <td class="first_name" data-id1="'.$row["userFirstname"].'" >'.$row["userFirstname"].'</td>  
                 <td class="last_name" data-id2="'.$row["userLastname"].'" >'.$row["userLastname"].'</td>  
                 <td class="payment" data-id3="'.$row["payment"].'" >'.$row["payment"].'</td>  
                 <td><button type="button" name="delete_btn" data-id4="'.$row["wmID"].'" class="btn btn-xs btn-danger btn_delete">Remit</button></td>  
            </tr>  
       ';
  }  

edit.php

<?php  
include_once('../connection.php');
$sql = "UPDATE tbl_request SET isRemitted = 'Yes' WHERE wmID = '".$_POST['id']."'"; 

$query = "INSERT INTO tbl_remit ('rAmount', 'rDate', 'rTime', 'wmID') VALUES 
('".$_POST['payment']."',$date,$time,'".$_POST['id']."')";

if(mysqli_query($conn, $sql) && mysqli_query($conn, $query))  
{  
  echo 'Payment Remitted' .mysqli_error($conn);  
}  else{
echo 'Rermittance failed' .mysqli_error($conn);  
}
?>

用于更新的ajax代码

      $(document).on('click', '.btn_delete', function(){  
       var id=$(this).data("id4");   
       var payment=$(this).data("id3");
       var firstname=$(this).data("id2");
       var lastname=$(this).data("id1");
       if(confirm("Is this really remitted?"))  
       {  
            $.ajax({  
                 url:"edit.php",  
                 type:"POST",  
                 data:{id:id,payment:payment},  
                 dataType: "text",  
                 success:function(data){  
                      alert(data);  
                      fetch_data();  
                 }  
            });  
       }  
  });

将所有数据放入按钮以触发值

 <td><button type="button" name="delete_btn" data-id1="'.$row["userFirstname"].'" data-id2="'.$row["userLastname"].'" data-id3="'.$row["payment"].'" data-id4="'.$row["wmID"].'" class="btn btn-xs btn-danger btn_delete">Remit</button></td>
