Question

我正在尝试从用户输入表单将用户信息添加到数据库中。表单中的数据正在被识别，如果我测试所有输入的变量的打印语句，则显示信息。当它通过insert语句时，它缺少第一列数据（lastname）并将所有其他数据推入错误的列。

姓氏列在firstname列中，firstname以联系人类型结束，联系人类型以联系人信息结束，联系人信息最终在城市，评论不会显示在任何地方，添加日期是正确的。

我添加了最相关的本地代码，但如果您需要常用功能，我也可以添加。底部还有桌子结构。

谢谢！

Answer 1

您对方法insertData()的调用是错误地传递参数：

$rtncode = insertData($db, $mylastname, $myfirstname, $mycontact_type, $mycontactinfo, $mycity, $mycomments);
...
function insertData($mylastname, $myfirstname, $mycontact_type, $mycontactinfo, $mycity, $mycomments) {

你传递$db作为第一个参数，但函数的第一个参数应该是姓氏。只需更新通话即可删除$db，您应该做得很好：

$rtncode = insertData($mylastname, $myfirstname, $mycontact_type, $mycontactinfo, $mycity, $mycomments);

Answer 2

我认为很明显电话之间存在不匹配：

 insertData($db, $mylastname, $myfirstname, $mycontact_type, $mycontactinfo, $mycity, $mycomments);

和实际签名：

 function insertData($mylastname, $myfirstname, $mycontact_type, $mycontactinfo, $mycity, $mycomments)

从通话中删除第一个参数$db。
