Database not updating before the page reloads?

I have a page that updates the database with the info that is input into the form, then goes back to a page that has a table that outputs the info. When it goes back to that page, the info is not changed, but if I go back to the search page and find it, it is changed... any ideas? Here is the code that updates the info...

	{
		$shop = $_POST["shop"];
		$email = $_POST["email"];
		$owner = $_POST["owner"];
		$owner_home = $_POST["owner_home"];
		$owner_cell = $_POST["owner_cell"];
		$manager = $_POST["manager"];
		$manager_cell = $_POST["manager_cell"];
		$address = $_POST["address"];
		$city = $_POST["city"];
		$state = $_POST["state"];
		$zip = $_POST["zip"];
		$shop_num = $_POST["shop_num"];
		$shop_fax = $_POST["shop_fax"];
		$windows = $_POST["windows"];
		$support = $_POST["support"];
		$pager = $_POST["pager"];
		$lic_dt = $_POST["lic_dt"];
		$sup_cost = $_POST["sup_cost"];
		echo $sup_cost;
		$bill_add = $_POST["bill_add"];
		$bill_city = $_POST["bill_city"];
		$bill_state = $_POST["bill_state"];
		$bill_zip = $_POST["bill_zip"];
		$former_name = $_POST["former_name"];
		$chain = $_POST["chain_store"];
		$result = mysql_query("SELECT * FROM customer WHERE shop LIKE '%$chain%'") or die(mysql_error()); //selects row for chains
		$row = mysql_fetch_array($result);
		if (0 == strlen($chain_store))
			{ $chain_store = 0; }
		else
			{ $chain_store = $row['chain_store']; } //selects the chain number
		echo "Customer has been updated.";
		mysql_query("UPDATE `customer` SET `shop`='$shop', `email`='$email', `owner`='$owner', `owner_home`='$owner_home', `owner_cell`='$owner_cell', `manager`='$manager', `manager_cell`='$manager_cell', `address`='$address', `city`='$city', `state`='$state', `zip`='$zip', `shop_num`='$shop_num', `shop_fax`='$shop_fax', `windows`='$windows', `support`='$support', `pager`='$pager', `lic_dt`='$lic_dt', `sup_cost`='$sup_cost', `bill_add`='$bill_add', `bill_city`='$bill_city', `bill_state`='$bill_state', `bill_zip`='$bill_zip', `former_name`='$former_name', `chain_store`='$chain_store' WHERE `cust_no`='$cust_no' LIMIT 1") or die(mysql_error());

		?>
		<script language="JavaScript">
		setTimeout("top.location.href = 'cust_info.php'",3000);
		</script>
		<?
	}

PHP:

It gives no mysql error...

 

Try using the PHP functione header location to send the browser back. I think the problem is the browser cache.

 

Pleae try to use following php code when you need to redirect user

header('Location: cust_info.php');
die();

PHP:

insted of JavaScript redirect.
