Running additional code in a module after Product Save

[rayzorMamon]

Hi guys, I added additioal fields to the Product New/Edit form and need to save them onto a new table in the database as well as post the data onto another website store api.  I have created the function to perform all of this but, I am not sure how this should be called.  Should I hardcode the function call inside the Product Save execute() function?

Sorry guys, I am really new to Magento and am struggling, hope ye all can help me out.

Thanks.

Ok did some research and it seems I can use custom Productsaveafter class but does any of you know how I can get the POST data in the execute method of Productsaveafter so I can pass them to the function i made?

How is the «catalog_product_save_after» event triggered and can be handled? https://mage2.pro/t/1238

 Thanks for the feedback, I am using Productsaveafter based on that catalog_product_save_after samplecode.  

I have also asked stack magento community and the answer to the issue regarding getting the POST is this:

class Productsaveafter implements ObserverInterface
{
protected $_request;
protected $_resource;
public function __construct(
    \Magento\Framework\App\RequestInterface $request
)
{
    $this->_request = $request;
}

public function execute(\Magento\Framework\Event\Observer $observer)
{
    $post_data = $this->_request->getPost()->toArray();
}
