javascript - 每个请求生成相同的跟踪代码

问题描述

我创建了动态请求表单，用户可以在其中添加多个表单，并且我有一个名为的字段trackingcode，它会生成 10 个随机字符，到目前为止一切正常。

目前，每个请求都会生成自己的trackingcode. 现在是否可以根据请求生成跟踪代码？

这是一个示例，我添加了 3 个表单：

形式

当我点击发送时，3 在我的数据库中应该有相同的跟踪代码。

我试图找到一些我可以阅读的关于它的文章，但我找不到任何东西。

这是我的插入代码：

<?php
//insert.php
$connect = mysqli_connect("localhost", "root", "", "pcrequest");
if(isset($_POST["reqname"]))

 $length = 10;

 $position = $_POST["position"];

 $phonetype = $_POST["phonetype"];
 $headset = $_POST["headset"];

 $query = '';

  $trackingcode_clean = substr(str_shuffle("0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"), 0, $length);

不确定这是否有必要，但这是我的 JS：

$('#save').click(function(){
  var trackingcode = [];
  var reqname = [];
  var date = [];
  var empname = [];
  var position = [];
  var account = [];
  var platform = [];
  var processor = [];
  var ram = [];
  var monitor = [];
  var phone = [];
  var phonetype = [];
  var headset = [];
  var approval = [];
  var status = [];
  $('.trackingcode').each(function(){
   trackingcode.push($(this).text());
  });
  $('.reqname').each(function(){
   reqname.push($(this).text());
  });
  $('.date').each(function(){
   date.push($(this).find('input').val());
  });
  $('.empname').each(function(){
   empname.push($(this).text());
  });
  $('.position').each(function(){
   position.push($(this).find('select').val());
  });
  $('.account').each(function(){
   account.push($(this).find('select').val());
  });
  $('.platform').each(function(){
   platform.push($(this).find('select').val());
  });
  $('.processor').each(function(){
   processor.push($(this).find('select').val());
  });
  $('.ram').each(function(){
   ram.push($(this).find('select').val());
  });
  $('.monitor').each(function(){
   monitor.push($(this).find('select').val());
  });
  $('.phone').each(function(){
   phone.push($(this).find('select').val());
  });
  $('.phonetype').each(function(){
   phonetype.push($(this).find('select').val());
  });
  $('.headset').each(function(){
   headset.push($(this).find('select').val());
  });
  $('.approval').each(function(){
   approval.push($(this).text());
  });
  $('.status').each(function(){
   status.push($(this).text());
  });
  $.ajax({
   url:"insert-message.php",
   method:"POST",
   data:{trackingcode:trackingcode, reqname:reqname, date:date, empname:empname, position:position, account:account, platform:platform, processor:processor, ram:ram, monitor:monitor, phone:phone, phonetype:phonetype, headset:headset, approval:approval, status:status},
   success:function(data){
    alert(data);
    $("td[contentEditable='true']").text("");
    for(var i=2; i<= count; i++)
    {
     $('tr#'+i+'').remove();
    }
    fetch_item_data();
   }
  });
 });

解决方案

删除$trackingcode_clean内部for循环并将值更改为：

VALUES("'.$trackingcode.'", "'.$reqname_clean.'", "'.$date_clean.'", "'.$empname_clean.'", "'.$position_clean.'", "'.$account_clean.'", "'.$platform_clean.'", "'.$processor_clean.'", "'.$ram_clean.'", "'.$monitor_clean.'", "'.$phone_clean.'", "'.$phonetype_clean.'", "'.$headset_clean.'", "'.$approval_clean.'", "'.$status_clean.'");
