I'm new to Magento2 and finding it difficult to get information. I'm trying to read simple (variants) products of a configurable product on the view page.

I created my custom block that extends AbstractProduct.

Then I was able to get upsell product ids like this:

$product = $this->_coreRegistry->registry('product');
$upSellProductIds = $product->getUpSellProductIds();

Now, how to get variants(simple products).

In Magento 1.x, I used getUsedProductCollection()

Please help

  • can you please show your working example I need the same but I can't get workin

Try with $product->getTypeInstance()->getUsedProducts($product).

  • should check condition if product is configurable then getUsedProducts() medthod work otherwise throw error.

You can get child product of current configurable product by this simple code:

    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $product = $objectManager->get('Magento\Framework\Registry')->registry('current_product');//get current product
    $productTypeInstance = $product->getTypeInstance();
    $usedProducts = $productTypeInstance->getUsedProducts($product);

    echo $product->getId(); //Main configurable product ID
    echo $product->getName(); //Main Configurable Name

    foreach ($usedProducts  as $child) {
        echo $child->getId()."</br>"; //Child Product Id  
        echo $child->getName()."</br>"; //Child Product Name
