I am trying to create a loop in PHP where for each extra item in a shopping cart, the shipping gets a ascending 10% discount.
This is the result I want:
etc.
I don't know where to place my $quantity variable now.
My PHP:
<?php
$quantity = 10;
$shipping = 30;
for( $discount = 0.5; $discount >= 0.1; $discount - 0.1 ) {
$shipping = $shipping + ( $shipping * $discount );
}
echo $shipping;
?>
you should iterate the quantity value, not the discount.
$shippingDefault = 30;
$discount = 0.5;
for ($i = 2 ; $i <= $quantity; $i++) {
if ($discount < 0.1) {
$discount = 0.1;
}
$shipping += ( $shippingDefault * $discount );
$discount -= 0.1;
}
