Hi there.

I have a select query

	$total_query = "SELECT `product_price` FROM `robin_basket` WHERE session_id = '".session_id()."'";
	$total_result = mysql_query($total_query);
	$total = mysql_fetch_assoc($total_result);

Now this query returns 3 results (as it should). However i need to add those three results together, and i'm not sure how to do this.

The results are:
So the total of them all should be 315.

I have attempted to solve this problem, by using the following code:

		do {
		$total_minus_shipping = array_sum($total);
		while ($total = mysql_fetch_array($total_result));

However, this only adds two results (giving me a total of 210) and not all three added together (which would result in 315).

If someone could explain to me how to get the results to add up correctly i'd be greatful.

If all you want is the total
$total_query = "SELECT SUM(`product_price`) 
            FROM `robin_basket` 
            WHERE session_id = '".session_id()."'";
$total_result = mysql_query($total_query);
$total = mysql_result($total_result, 0, 0);

If you are still using mysql_ functions, STOP! Use mysqli_ or PDO. The longer you leave it the more you will have to rewrite.

Works like a charm. Think i'll go check out all the mysql functions now see if there are any more gems to make the coding easier.

Thanks again.
