<?
include("inc/conn.php");
if ($Submit=="确认")
{
$Sql = "select * from sms_user where username='$name' and pass='$password'";
echo $Sql;
exit;
$Rs = odbc_do($Conn,$Sql) or die("$Sql查询出错"); //执行取得数据SQL语句
$user_id = odbc_result($Rs,1);
$numclient =odbc_num_rows($Rs);
echo $numclient;
exit;
if ($numclient < 1)
{
echo "<script language=javascript>";
echo "alert('用户名或密码错误，请重新填写');";
echo "</script>";
}
else
{
echo "<script language=javascript>";
echo "location='main.php';";
echo "</script>";
}
}
?>
$numclient 总是返回-1
因为我数据库里有值啊，可是返回的值是-1
所以总是执行"alert('用户名或密码错误，请重新填写');";这句话，请问怎么办
