php - 无法插入到 php 中的表中，从 url 检索值

Question

我正在制作一个电子商务网站作为一个学期项目，同时尝试将值插入到表中。我有一个包含 5 列的表，第一列是自动递增的主键。当我尝试插入时，它会在第二列中插入值，同时将接下来的两列留空并在第五列中插入 0。我尝试回显页面上的值以检查它们是否正在通过 url 检索，并且它们有效。它也没有显示错误。我已经突出显示了我遇到问题的部分。
我的 table :

这是完整的代码 Code。它是一种显示所有客户详细信息及其购买的产品的账单。

Answer 1

您似乎在查询中的 VALUES 之前遗漏了一个空格:

$sql=mysql_query("INSERT INTO shipping_payment_details(customer_id,payment_type,shipping_type,card_no)VALUES('$cust_id','$payment_type','$shipping_type','$card_no')") or die(mysql_error());

应该是:

$sql=mysql_query("INSERT INTO shipping_payment_details(customer_id,payment_type,shipping_type,card_no) VALUES('$cust_id','$payment_type','$shipping_type','$card_no')") or die(mysql_error());
