Deleting records - mySQL / PHP

Question

I've just worked through this whole database thing from
scratch again after a little glitch, and it's all working pretty
well.
I do still have the issue with deleting records - I have the
search results page which is fine, and has a delete options at the
end of the row.
It was working just fine bringing up the 'confirm deletion'
page with the selected record - but it goes wrong after I add the
'delete record' server behaviour.
Basically after I do, when I click delete in the results
page, it skips the 'confirm deletion' page, going straight to the
'deletion confirmed' page.
It does still delete the record at least, but it would be
good to have the confirmation page.
Here's a
link
(if you need to log in use 'admin' and 'password'.)
This is all the script code in the 'confirm delete' page :
<?php require_once('../Connections/ConnHandprint.php');
?>
<?php
function GetSQLValueString($theValue, $theType,
$theDefinedValue = "", $theNotDefinedValue = "")
$theValue = (!get_magic_quotes_gpc()) ?
addslashes($theValue) : $theValue;
switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" :
"NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? "'" . doubleval($theValue) .
"'" : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" :
"NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue :
$theNotDefinedValue;
break;
return $theValue;
if ((isset($_GET['recordID'])) && ($_GET['recordID']
!= "")) {
$deleteSQL = sprintf("DELETE FROM Contacts WHERE
ContactID=%s",
GetSQLValueString($_GET['recordID'], "int"));
mysql_select_db($database_ConnHandprint, $ConnHandprint);
$Result1 = mysql_query($deleteSQL, $ConnHandprint) or
die(mysql_error());
$deleteGoTo = "contactdeleted.php";
if (isset($_SERVER['QUERY_STRING'])) {
$deleteGoTo .= (strpos($deleteGoTo, '?')) ? "&" : "?";
$deleteGoTo .= $_SERVER['QUERY_STRING'];
header(sprintf("Location: %s", $deleteGoTo));
$colname_Recordset1 = "1";
if (isset($_GET['recordID'])) {
$colname_Recordset1 = (get_magic_quotes_gpc()) ?
$_GET['recordID'] : addslashes($_GET['recordID']);
mysql_select_db($database_ConnHandprint, $ConnHandprint);
$query_Recordset1 = sprintf("SELECT * FROM Contacts WHERE
ContactID = %s", $colname_Recordset1);
$Recordset1 = mysql_query($query_Recordset1, $ConnHandprint)
or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);
?>
Any ideas?
Cheers,
Iain

Hi,
It is a good idea to do it in database level such that declare foreign key from child to parent table and specify DELETE CASCADE.
