Math not working right.

[ipwnzphp]

$balanc = mysql_query("SELECT * FROM `jos_vm_vouchers` WHERE voucher_number = '$cop_code'") or die (mysql_error());
$balan = mysql_fetch_array($balanc);

$amount = $balan['voucher_value'];

setcookie("vouch_price", $amount, time()+(60*60*24*5), "/", "");

echo $_COOKIE['vouch_price'];

if (isset($_COOKIE['vouch_price'])) {
$order_total = $_COOKIE['vouch_price'] - $total;
} else {
$order_total += $shipping_total + $total;
}

 

say the cookie is 155 and the price is 35 well. the amount is coming back as 120 but it should come back as 0 why is it not working?

probably will explain things.

[ipwnzphp]

what dose time half to do with math?

[cooldude832]

time = unix time stamp = a number not what u think it is probably

[ipwnzphp]

umm? could you show some code?

[MasterACE14]

the time() function, returns the seconds since some date a long time ago. I think it was January 1st, 1960, or something like that.

[ipwnzphp]

but im not dealing with dates here im dealing with $$$

well you have the line

setcookie("vouch_price", $amount, time()+(60*60*24*5), "/", "");

but I see that is setting a cookie length time

[ipwnzphp]

i am setting the $$ in the cookie

say the cookie is 155 and the price is 35 well. the amount is coming back as 120 but it should come back as 0 why is it not working?

 

Sorry, but none of that makes any sense. Your problem is actually?

[ipwnzphp]

$amount = "155";

// Cookie = 155
setcookie("vouch_price", $amount, time()+(60*60*24*5), "/", "");

if (isset($_COOKIE['vouch_price'])) {
$order_total = $_COOKIE['vouch_price'] - $total;
} else {
$order_total += $shipping_total + $total;
}

 

the price of $total = 35 the price of the cookie = 155 now when it comes back it says 120 insted of saying 0.00 for the total of the order.

Doesn't that mean it's working? O_O

[ipwnzphp]

it dosent work right

[trq]

it dosent work right

 

155 less 35 equals 120. Its pretty simple.

[ipwnzphp]

yea i know that but it should say 0.00 this is a gift card coupon

[trq]

Your not making sense.

Having set a cookie value, the value of that cookie is not available until the the next page load.
