我有一个有效的注册和登录系统。我正在尝试创建一个用户可以添加产品注册信息的表单（通过mysql更新）。我似乎无法让db实际更新字段。我在这里想念的是什么？！？

答案 0 :(得分：0)
您的更新查询已关闭。您需要以
的形式执行此操作UPDATE `tablename`
SET col1=`value`,col2=`val2`
WHERE wherecol=`whereval`
更改您的查询，看看是否有帮助。
您的查询应该是
UPDATE electrix_users
SET
product1= $_POST['product1'],
serial1 = $_POST['serial1'],
product2 = $_POST['product2'],
serial2 = $_POST['serial2'],
product3 = $_POST['product3'],
serial3 = $_POST['serial3']
WHERE usr=$_POST['username']
但是，对于任何用户输入的数据，您应该始终清除sql注入。我没有在示例中这样做，因为这是你应该以自己的方式做的事情。这个例子是作为一个例子给你的，并没有阻止任何类型的SQL注入现在。
总是做什么可以防止SQL注入！
