MrL8Knight Posted March 8, 2006 Share Posted March 8, 2006 I am building a simple shopping cart and I am having problems trying to add the costs of the items to generate a total cost. I am new at this so forgive me if my technical verbiage isn’t the greatest!I am trying to sum specific values in my arrays (or the price portions of the arrays). I have tried every imaginable way with the array_sum command and nothing has worked for me!Here is what my cookie information looks like after I put 2 test items into the cart that cost 18.00 each.Array ( [0] => 21 [1] => test1 [2] => 12 [3] => 12 [4] => 1 [5] => Please select [6] => Please select [7] => Please select [8] => [9] => 18.00 ) Array ( [0] => 22 [1] => test2 [2] => 12 [3] => 12 [4] => 1 [5] => Please select [6] => Please select [7] => Please select [8] => [9] => 18.00 ) Arrays 21 and 22 both contain items with a price of 18.00I am trying to add both of the [9] fields (18.00) to come up with a total costHere is the code I am using to try to add the price of both items:<?foreach ($_COOKIE[mycookie] as $valueq) {$value3 = unserialize(stripslashes($valueq));}echo "Total Cost = " . array_sum($value3) . "\n";?>When I load this page, it comes up with a total of 65 instead of 36 (18+18)I’m thinking the problem is that I am summing all the values when I just need to sum the values of the [9] field which contains the prices.Any help would be greatly appreciated!!!!!!MrL8Knight Quote Link to comment https://forums.phpfreaks.com/topic/4405-help-summing-specific-values-from-a-cookie-array/ Share on other sites More sharing options...

MrL8Knight Posted March 8, 2006 Author Share Posted March 8, 2006 loguThank you for your post, much respect, I tried the script and it gave me a sum of 0 instead of 36. I have posted your code for you to see how I had implemented it, maybey I was missing something.<?$total =0;$temp = $_COOKIE[mycookie] ;for($i=0;$i<count($temp);$i++){$total += $temp[$i][9];}echo "Total Cost = $total";?>[b]BUT WAIT!!!!![/b]I just got my hands on the script to make it work properly from the Guru Banfa Here it is<? $total = 0; foreach ($_COOKIE[mycookie] as $valueq) { $value3 = unserialize(stripslashes($valueq)); $total += $value3[9]; } echo "Total Cost = " . $total . "\n"; ?> Thanks again, back in the running!!!MrL8Knight Quote Link to comment https://forums.phpfreaks.com/topic/4405-help-summing-specific-values-from-a-cookie-array/#findComment-15333 Share on other sites More sharing options...
