data not being added to MySql DB

[richiejones24]

The script below used to work fine but the HTTP_REFERER was unreliable so i added a re-direct if the HTTP_REFERER was unavailable and now nothing is being added to the MySQL BD, the script runs ok ie it sends the user back to where they come from, any ideas what could be wrong? 

 

<?php
require("../include/mysqldb.php");
$uinwish = $_GET['uinwish'];
$wishrefer = $_SERVER['HTTP_REFERER'];
$wishdate  = mktime(0, 0, 0, date("m"), date("d")+3, date("Y"));
$rand_wish_cookie = $_COOKIE["wishtracking"];

$con = mysql_connect("$dbhost","$dbuser","$dbpass");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("$dbame", $con);

//DB Stuff start code below

//check if the uin and cookie have already been stored together.
$sql = "select * from Wish_list_guest where usercookie='$rand_wish_cookie' and uinwish='$uinwish'";
$result = mysql_query($sql);


$row = mysql_fetch_row($result);
if (mysql_num_rows($result)!= 1) {

$issetvar = "1";

if (!isset ($wishrefer)){

$host  = $_SERVER['HTTP_HOST'];
$extra = 'profile.php?uin=';
header("Location: http://$host/$extra$uinwish");
exit;
}

if (isset ($wishrefer)){

header("Location: $wishrefer");
exit;
}
}

if ($issetvar = 1) {

mysql_query("INSERT INTO Wish_list_guest (usercookie, date_delete, uinwish, referwish)
VALUES ('$rand_wish_cookie', '$wishdate', '$uinwish', '$wishrefer')");

mysql_close($con);


if (!isset ($wishrefer)){

$host  = $_SERVER['HTTP_HOST'];
$extra = 'profile.php?uin=';
header("Location: http://$host/$extra$uinwish");
exit;
}

if (isset ($wishrefer)){

header("Location: $wishrefer");
exit;
}
}


?>
