Question

我有一个带有订单号，订单日期，信纸类型，信纸数量字段的表格（例如发票），这里信纸类型和信纸数量不止一个。我试图将数据插入表中，但是插入按钮不起作用。提交按钮没有反应，没有向表中插入任何值。我的代码太长了，请耐心等待

<?php
session_start();
error_reporting(0);
include('includes/config.php');

if(isset($_POST['submit']))
    for($count = 0; $count < count($_POST["item_name"]); $count++)

$txntype='received';
$orderno=$_POST['orderno'];
$orderdate=$_POST['orderdate'];   
$stationerytype=$_POST['item_unit'];

问题在于您正在检查：

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

来自Jquery文档（Jquery serialize() doc）-

注意：只有“成功控件”才被序列化为字符串。由于没有使用按钮提交表单，因此没有序列化提交按钮的值

因此，您正在检查未发布的元素。

相反，您可以这样做：

if(isset($_POST['item_name']))

或更妙的是：

if ($_SERVER['REQUEST_METHOD'] == 'POST')

无法在数据库中插入多个记录
