After add to cart event magento
Sometime we want to give discount after add to cart product or unset/set session after add to cart product for this situation i have created a small script.
Put below code in your module/any module config.xml file after <models> block
<global>
<events>
<checkout_cart_product_add_after>
<observers>
<Setblue_Banner_Model_Observer>
<type>singleton</type>
<class>Setblue_Banner_Model_Observer</class>
<method>addtocartEvent</method>
</Setblue_Banner_Model_Observer>
</observers>
</checkout_cart_product_add_after>
</events>
</global>
Next we need to create observer file to read this code. Create Observer.php in /yourmodule/Model/Observer.php and put the below code :
class Setblue_Banner_Model_Observer
{
public function addtocartEvent(Varien_Event_Observer $observer) {
// Do something here
//unset($_SESSION['stitch5']);
/*$event = $observer->getEvent(); //Gets the event
$product = $event->getProduct();
$observermsg = "The product added successfully";
//Adds the message to the shopping cart
echo Mage::getSingleton('checkout/session')->addSuccess($observermsg);*/
}
}
