You can try the following. This will check if the quantity is bigger than 1. If this is the situation then we will update the quantity to 1. We also add a notice message so the user is informed about the quantity change. <pre><code><checkout_cart_product_add_after> <observers> <company_module_name> <type>singleton</type> <class>Company_Module_Model_Observer</class> <method>checkItem</method> </company_module_name> </observers> </code></pre> <pre><code>public function checkItem($obj) { //check if qty is more then 1 if($obj->getProduct()->getQty() > 1) { //set notice to inform the visitor that there is a maximum Mage::getSingleton('core/session')->addNotice('The maximum quantity allowed for purchase is 1.'); //get the event $event = $obj->getEvent(); //get the product we have added $product = $event->getProduct(); //get the quote item $quoteItem = $event->getQuoteItem(); //change the qty to 1 allowed $quoteItem->setQty(1); //recalc totals $quoteItem->getQuote()->collectTotals(); //save the item $quoteItem->getQuote()->save(); } </code></pre> ===== EDIT ====== Another option would be: <pre><code><controller_action_predispatch_checkout_cart_add> <observers> <aquait_aquait_name> <type>singleton</type> <class>Aquait_Aquait_Model_Observer</class> <method>checkfunction</method> </aquait_aquait_name> </observers> </controller_action_predispatch_checkout_cart_add> public function checkfunction($observer) { if ($observer->getEvent()->getControllerAction()->getFullActionName() == 'checkout_cart_add') { $productId = Mage::app()->getRequest()->getParam('product'); $product = Mage::getModel('catalog/product')->load($productId); if (Mage::app()->getRequest()->getParam('qty') > 1) { Mage::getSingleton('core/session')->addNotice('The maximum quantity allowed for purchase is 1.'); Mage::app()->getResponse()->setRedirect($product->getProductUrl()); } } } </code></pre>

1. COWorks great, Mage::getSingleton('core/session')->addNotice('...'); even throws the correct message. However, it doesn't stop the product from being added to the cart. I've tried throwing an exception -- that works -- however it sends the user to an exception page. Ideally, I'd like to kill the add to cart event from my observer. I just can't seem to figure it out...

2. COHi Nick i have edited the answer. I did add another possible solution. I did log the events called when i added a product to the cart. Since "checkout_cart_product_add_before" does not exist. i have used a predispatch event. Let me know if this works for you.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
