Check if specific product has been bought on success page - php

Question

On the success page after checkout (success.phtml), I'd like to run a script only if a certain product ID has been bought. Is this possible?
I'm using Magento 1.4.2.

Answer 1

Try adding this to Success.phtml
$order = Mage::getModel('sales/order')->loadByIncrementId($this->getOrderId());
$items = $order->getItemsCollection();
$sku = $ids = array();
foreach($items as $item){
//$sku[] = $item->getSku();
$p_ids[] = $item->getProductId();
}
$p_id = 16;
if(in_array($p_id, $p_ids)){
//run script
}

Answer 2

This sort of logic might work on success.phtml page.
$
if($this->getOrderId()) {
$found = false;
$skuToFind = 'abc';
$order = Mage::getModel('sales/order')->loadByIncrementId($this->getOrderId());
$items = $order->getAllItems();
foreach ($items as $i => $item) {
if($item->getSku() == $skuToFind) {
$found = true; break;
}
}
if($found) { echo "Product Found"; } else { echo "No Found"; }
?>

Well, you only need to find the cart variables. I'm not sure the exact variables but echoing out the $_SESSION will show you where they are. Check out the following example code:
if(in_array('2324242', $_SESSION['product_ids'])
{//in this case 2324242 is the product ID you are looking for
//Require_once ('script');
//Or redirect to script.php
}
