My Observer :
<?php
class Gta_KolupadiRestrict_Model_Observer {
public function cartevent(Varien_Event_Observer $observer) {
// Load product
$product = $observer->getProduct();
$prodID = $product->getId();
$_product = Mage::getModel('catalog/product')->load($prodID);
// get category id
$categoryIds = $_product->getCategoryIds();
// check cart
$cart_qty = (int) Mage::getModel('checkout/cart')->getQuote()->getItemsQty();
if(in_array(681, $categoryIds))
{
error_log("line 31-".$categoryIds[0]);
$quote = Mage::getModel('checkout/cart')->getQuote();
foreach ($quote->getAllItems() as $item) {
$_product1 = $item->getProduct();
$categoryIds1 = $_product1->getCategoryIds();
if(!in_array(681, $categoryIds1)) {
Mage::throwException("If you want Kolu Padi, Purchase alone not mixed with other Products");
}
}
}elseif(!in_array(681, $categoryIds)){
error_log("line 31-".$categoryIds[0]);
$quote = Mage::getModel('checkout/cart')->getQuote();
foreach ($quote->getAllItems() as $item) {
$_product1 = $item->getProduct();
$categoryIds1 = $_product1->getCategoryIds();
error_log("line 34-".$item->getProductId()."-".$categoryIds1[0]);
if(in_array(681, $categoryIds1)) {
Mage::throwException("If you want Kolu Padi, Purchase alone not mixed with other Products");
}
}
}
}
}
?>Observer & my logic working fine, but observer not throw exception message instead of keep loading add-to-cart. How to show exception if condition match?
