在列上插入语句&；缺少数据 - Insert statement pushing over a column & missing data

我正试图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，如果我为所有输入的变量测试打印语句，信息就会显示出来。然而，当它执行insert语句时，它缺少第一列数据（lastname），并将所有其他数据推送到错误的列中。

姓氏显示在名字列中，名字显示在联系人类型中，联系人类型显示在联系人信息中，联系人信息显示在城市中，评论不会显示在任何地方，添加的日期是正确的。

我已经添加了最相关的本地代码，但如果您需要通用函数，我也可以添加。底部还有表格结构。

谢谢！

表格结构：

CREATE TABLE u1585_Guestbook (
  guest_id int(11) NOT NULL AUTO_INCREMENT,
  lastname varchar(40) NOT NULL,
  firstname varchar(30) NOT NULL,
  contact_type varchar(30) NOT NULL,
  contact_info varchar(40) NOT NULL,
  city varchar(40) NOT NULL,
  comments varchar(200) NOT NULL,
  date_added date NOT NULL,
  PRIMARY KEY (guest_id)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

您对方法insertData()的调用错误地传递了参数：

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

传递$db作为第一个参数，但函数的第一个参数应该是姓氏。只需更新调用以删除$db，您就应该很好：

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

我认为调用之间显然不匹配

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

和实际签名：

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

从调用中删除第一个参数$db。
