\"Magento<\/a><\/figure>\n<\/div>\n\n\n

In magento Observer  catch magento events and run your function after that event. Magento events like  checkout_cart_product_add_after,checkout_cart_save_after etc you can get more magento events from Magento Events Cheat Sheet (1.7.0.0)<\/a><\/p>\n\n\n\n

This way of adding custom event before and after save is useful when we just need to add or do something before or after any Magento core event. For example, setting some values to some attributes before or after product is saved.<\/p>\n\n\n\n

For this, you just need to add add some event observer code in your module\u2019s YourModule\/etc\/config.xml<\/strong>file and add a new observer YourModule\/Model\/Observer.php<\/strong><\/p>\n\n\n\n

In the example code below, I have added before and after event hook for customer address and catalog product. Customer address event hooks run before and after saving customer address and catalog product hooks run before and after saving products in admin.<\/p>\n\n\n\n

customer_address_save_before<\/strong> = runs just before saving customer address
customer_address_save_after<\/strong> = runs immediately after saving customer address<\/p>\n\n\n\n

catalog_product_save_before<\/strong> = runs just before saving product
catalog_product_save_after<\/strong> = runs just before saving product<\/p>\n\n\n\n

Here\u2019s the code:-<\/p>\n\n\n\n

config.xml<\/strong><\/p>\n\n\n\n

<global>\n    <events>             \n        <customer_address_save_before>\n            <observers>\n                <yourmodule>\n                    <type>singleton<\/type>\n                    <class>yourmodule\/observer<\/class>\n                    <method>customer_address_save_before<\/method>\n                <\/yourmodule>\n            <\/observers>\n        <\/customer_address_save_before>\n\n        <customer_address_save_after>\n            <observers>\n                <yourmodule>\n                    <type>singleton<\/type>\n                    <class>yourmodule\/observer<\/class>\n                    <method>customer_address_save_after<\/method>\n                <\/yourmodule>\n            <\/observers>\n        <\/customer_address_save_after>\n\n        <catalog_product_save_before>\n            <observers>\n                <yourmodule>\n                    <type>singleton<\/type>\n                    <class>yourmodule\/observer<\/class>\n                    <method>catalog_product_save_before<\/method>\n                <\/yourmodule>\n            <\/observers>\n        <\/catalog_product_save_before>\n\n        <catalog_product_save_after>\n            <observers>\n                <yourmodule>\n                    <type>singleton<\/type>\n                    <class>yourmodule\/observer<\/class>\n                    <method>catalog_product_save_after<\/method>\n                <\/yourmodule>\n            <\/observers>\n        <\/catalog_product_save_after>    \n    <\/events>\n<\/global><\/pre>\n\n\n\n
Observer.php<\/strong><\/p>\n\n\n\n
class YourNamespace_YourModule_Model_Observer\n{  \n    public function customer_address_save_before($observer)\n    {\n        $address = $observer->getCustomerAddress();\n        \/\/echo "<pre>"; print_r($address->getData()); exit;\n        \/\/ do something here\n    }\n\n    public function customer_address_save_after($observer)\n    {\n        $address = $observer->getCustomerAddress();     \n        \/\/echo "<pre>"; print_r($address->getData()); exit;\n        \/\/ do something here\n    }\n\n    public function catalog_product_save_before($observer)\n    {\n        $product = $observer->getProduct();     \n        \/\/echo "<pre>"; print_r($product->getData()); exit;\n        \/\/ do something here\n    }\n\n    public function catalog_product_save_after($observer)\n    {\n        $product = $observer->getProduct();     \n        \/\/echo "<pre>"; print_r($product->getData()); exit;\n        \/\/ do something here\n    }\n}<\/pre>\n\n\n\n
Similarly, you can add your custom function to other events like\u00a0sales_order_save_before<\/strong>,sales_order_save_after<\/strong>,\u00a0sales_order_invoice_save_before<\/strong>,\u00a0sales_order_invoice_save_after<\/strong>, etc.<\/p>\n","protected":false},"excerpt":{"rendered":"
