How to get current product id from custom block?

Question

I've problem to get current product id from custom block displayed on product page. Here my code :

class TestBlock extends BlockBase {


  public function build() {


$product = \Drupal::routeMatch()->getParameter('node');

$productid = $product->product_id();

return array(
 '#markup' => $this->t('Product ID : ') . '<h2>' . $productid . '</h2>',      

    );
  }

}

Do you have any idea to get the current ID from product ?

Thank you for your help.

Answer 1

Use this below code to get product ID

$product_id = \Drupal::routeMatch()->getParameter('commerce_product')->id(); 

and then return the value in custom block,

return [      
      '#product_id' =>  $product_id,
    ];

Answer 2

Like, such code should work:

$product_id = \Drupal::routeMatch()->getRawParameter('commerce_product');

But in my case it is not working. But it work:

$paramList = \Drupal::routeMatch()->getRawParameters();
foreach($paramList as $paramName=>$paramVal) {
    // save params to any variables...
}
