I have a quick question, how can we get the POST data inside the execute method of Productsaveafter class? I added new input fields in the Product form page in admin and would like to save them onto a new table.

class Productsaveafter implements ObserverInterface
    public function execute(\Magento\Framework\Event\Observer $observer)
        $product = $observer->getEvent()->getRequest(); 
        $productData = $product->getData('params');
        echo "<pre>"; print_r($product); exit;
  • You could try: $post = $this->getRequest()->getPostValue(); – tecjam Apr 13 '16 at 14:17
  • unfortunately, it does not work. i also tested $observer->getRequest()->getPostValue(); also error. although when I do a print_r($observer) I can see the post data. – Rahahaha Apr 13 '16 at 14:26
  • this is the one I see, i just don;'t have any idea how to extract it: [postParams:protected] => Zend\Stdlib\Parameters Object ( [storage:ArrayObject:private] => Array ( [form_key] => tiQ1H13YxgAHBLPi [product] => Array ( [name] => testAfterSave [sku] => testAfterSave [price] => 1,200.00 – Rahahaha Apr 13 '16 at 14:36
  • maybe you could use the toArray() function and then get it from the array? – tecjam Apr 13 '16 at 14:52

In your observer constructor do:

public function __construct(
    \Magento\Framework\App\RequestInterface $request
    $this->_request = $request;

Then in your code use $this->_request to fetch post params.

  • i tried this and this is indeed what i am looking for. Thanks Petar. – Rahahaha Apr 14 '16 at 5:39

You can get data from $oberver, example bellow :

   ['controller' => $this, 'product' => $product]

In this example product is pass to event, so in your observer, you can get this variable :

 public function execute(Observer $observer)
    $product = $observer->getData('product');
    $sku = $product->getSku();

Hope this help someone :) Will
