Add to Cart call inside extension

[JoelAzevedo]

I, I am new to Magento and I need to build a simple extension that injects relevant videos to product pages.

 I want to know if it is possible, inside an extension, to know if a user made a click on Add to Cart. If yes, how?

Thanks

Maybe you can use observers. You can listen for checkout_cart_product_add_before event to do something.

There are another events like:

• checkout_cart_add_product_complete
• checkout_cart_product_add_after

Listening for those events you'll be able to trigger any other action.
