我不知道从哪里获取大小值并将其输入我的数据库

这是我的数据库表，名为transaksi，带有这些列 idtransaksi，noinvoice，idproduk，size，jumlah

这是我的脚本

chart.php 

<?php

和chart.action.php 

<?php
session_start();

require_once ('../inc/config.php');
require_once ('../inc/function.php');
require_once ('../chart/chart.inc.php');
$idpelanggan=$_SESSION['idpelanggan'];
/* menambahkan kode pesan dan detail pesan kedalam database*/
$kd_transaksi = kd_transaksi();
$total_bayar = $_SESSION['totalbayar'];
insertToDB($kd_transaksi,$idpelanggan,$total_bayar);
//check if query successful

$link="location:../index.php?mod=chart&pg=chart_ship&total_bayar=$total_bayar&kd_transaksi=$kd_transaksi";
    header($link);
?>

仍然对如何向数据库输入大小值感到困惑。如果您需要更多信息来帮助我告诉我我必须做什么

由于

1 个答案:

答案 0 :(得分：3)

函数insertToDB在上面的代码中定义了4个参数：

function insertToDB($kd_transaksi, $idpelanggan, $totalbayar, $sizes) {

但只用3个值调用它：

insertToDB($kd_transaksi,$idpelanggan,$total_bayar);

所以我建议在调用函数时传递变量size的值：

insertToDB($kd_transaksi,$idpelanggan,$total_bayar,$_POST["size"]);

顺便说一句：评论者@giraff在表达SQL注入时是绝对正确的。您的脚本容易受到攻击。您一定要检查并清理用户提交的数据！
