I got a error message when I run my
php
however the result is come out
this is my code
function cart() {
foreach($_SESSION as $name => $value) {
if ($value>0) {
if (substr($name, 0, 5) == 'cart_'){
$id = substr($name, 5, (strlen($name)-5));
$get = mysql_query('SELECT id, name, price FROM products WHERE id=' .mysql_real_escape_string((int)$id));
while ($get_row = mysql_fetch_assoc($get)){
$sub = $get_row['price'] * $value;
echo $get_row['name'].' x '.$value.' @ £'.number_format($get_row['price'], 2).' = £'.number_format($sub, 2).' <a href="cart.php?remove='.$id.'">[-]</a> <a href="cart.php?add='.$id.'">[+]</a> <a href="cart.php?delete='.$id.'">[Delete]</a><br />' ;
}
}
$total += $sub;
}
}
echo $total;
}
?>
I got a error message
Notice: Undefined variable: total in C:\xampp\htdocs\shoppingcart\cart.
php on line 54
which line 54 is
echo $total;
what's wrong with my code??
I think I have defined the code in
$total += $sub;
thanks for helping me :)
