php mysql delete ขอโค้ดที่ทำให้มัน refresh อยู่หน้าเดิม เมื่อกดลบข้อมูล ครับ

<?php echo '<script>window.location.href = '\'ชื่อไฟล์ที่ต้องการจะไป\''</script>';?>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script>
function back1(){
		alert("complete");
      location.href="admin_manu1.php";
}
</script>
<?
include('config.inc.php');
$strSQL = "DELETE FROM register_dorm_online ";
$strSQL .="WHERE UserID_study = '".$_GET["CusID"]."' ";
$objQuery = mysql_query($strSQL);
mysql_query("SET NAMES UTF8");

if($objQuery)
{
	echo '<script>back1();</script>';
}
else
{
	echo "<script language='javascript'>alert('error');history.back();</script>";
}
mysql_close();
?>

อีกเเบบ
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script>
function back1(){
		alert("complete");
      location.href="admin_manu3.php";
}
</script>
<?
$id=$_GET["id"];
include('config.inc.php');
$strSQL = "DELETE FROM register_dorm_online ";
$strSQL .="WHERE UserID_study = '".$_GET["CusID"]."' ";
$objQuery = mysql_query($strSQL);
mysql_query("SET NAMES UTF8");

if($objQuery)
{
	echo "$id";
	echo "<meta http-equiv='refresh' content='0; url=../online56_080156/admin_manu3.php?id=$id '>";
}
else
{
	echo "<script language='javascript'>alert('error');history.back();</script>";
}
mysql_close();
?>

delete.php?id=123&page=2

$sql = "delete ....";
mysql_query($sql);

echo "<script>window.location.href = 'webpage.php?page=$_GET[page]' </script>";
exit();
