可以用这样的形式写么？一直插入不进去
<?php
session_start();

$id=$_SESSION['id'];
$serverLink = @mysql_connect("localhost","root","root") or die("连接服务器失败!程序中断执行!");
mysql_query("set names 'gbk'");
$dbLink = @mysql_select_db("dormitory") or die("选择当前数据库失败!程序中断执行!");
$selectSQL = "select * from student where id ='$id'";
$resultSet = mysql_query($selectSQL,$serverLink);
$num=mysql_fetch_row($resultSet);
/*$name=$num[2];
$sex=$num[3];
$zy=$num[4];
$sunum=$num[5];*/
$intime=$_POST["in"];
$outtime=$_POST["out"];
$insertSQL="insert into people values("$num[2]","$num[3]","$num[4]","$num[5]",'$outtime','$intime')";
$inserted = mysql_query($insertSQL);
if($inserted)
{
$insertedRows = mysql_affected_rows();
echo "<script language=javascript>alert('登记成功');history.back();</script>";
}
else
{
echo "<script language=javascript>alert('登记失败！');history.back();</script>";
}
?>

/*$name=$num[2]; 有注释开始，没有注释结束。语法错！ $insertSQL="insert into people values("$num[2]","$num[3]","$num[4]","$num[5]",'$outtime','$intime')"; 双引号中出现了未转义的双引号。语法错！ $inserted = mysql_query($insertSQL) or die(mysql_error()); 前面都有判错，这里为何没有？
