eCart - get total items of specific category

eCart - get total items of specific category

I am trying to get the total number of items with a specific category that are currently in the cart to give the client an idea of how many more they need to add in order to receive a discount. How do I do that. I tried modifying a discount rule to do it, but I get PHP errors.

Fatal error: Call to undefined function ConditionalTotal() in /home/createwi/public_html/store/crystals/index.php

$discountSchedule = array(16,32,48,64,80,96,112,128,144,160,176,192,208,224,240,256,272,288,304);
function getDiscount($cartNumber){
if (true && ($cartNumber > 0) && ($cartNumber < $discountSchedule[0])) {
$numberRequired = ($discountSchedule - $cartNumber);
$discountMessage = 'You are just '.$numberRequired.' crystals away from a $16 discount.';
}

}

Then the call from the page.
<?php getDiscount(ConditionalTotal("Quantity", "Category", "1")); ?>

The cart is included at the top of the page.

this code:
<?php getDiscount(ConditionalTotal("Quantity", "Category", "1")); ?>


should be:
<?php getDiscount(CreateWindow->ConditionalTotal("Quantity", "Category", "1")); ?>

Thanks Jason, Worked Perfectly!

I changed the function a bit, but it works exactly like I wanted:
<?php

function getDiscount($cartNumber){
$discountSchedule = array(0,16,32,48,64,80,96,112,128,144,160,176,192,208,224,240,256,272,288,304);
for($i = 0; $i < count($discountSchedule); $i++) {
if (true && ($cartNumber > $discountSchedule[$i]) && ($cartNumber < $discountSchedule[($i + 1)])) {
$numberRequired = floatval($discountSchedule[$i + 1] - $cartNumber);
if($i == 0){
$discount = 'a $16 discount.';
} else {
$discount = 'an additional $16 discount.';
}
$discountMessage = 'You are just '.$numberRequired.' crystals away from '.$discount;
echo $discountMessage;
}
}
}
?>
