Getting simple product in observer when adding configurable product to cart?

Question

Magento 2.4.6

I am trying to get the simple product of a configurable product when a product is added to the cart. I am listening to the checkout_cart_product_add_after event. This is what I have so far:

$item = $observer->getEvent()->getData('quote_item');
$item = ($item->getParentItem() ? $item->getParentItem() : $item);
$logger->info('item: ' . $item->getName());

This however, always gives me the name of the configurable, not the child simple products name. No matter what I try to access, its always the data from the parent configurable. Any ideas whats wrong here?

Thanks!

Answer 1

• To access the child simple product's data, you need to make use of the getOptionByCode method.

• By using the getConfigurableOptions method, you can retrieve the selected options for the configurable product.

• Assuming there's only one configurable attribute, the first option's value will represent the child product's ID. You can then load the child product using getUsedProductById and access its name using $childProduct->getName().

• This approach should give you the name of the child simple product instead of the parent configurable product.

Here is the example code,

$item = $observer->getEvent()->getData('quote_item');
$item = ($item->getParentItem() ? $item->getParentItem() : $item);

// Get the selected options for the configurable product
$options = $item->getProduct()->getTypeInstance()->getConfigurableOptions($item->getProduct());

// Get the first option (assuming there's only one configurable attribute)
$selectedOption = reset($options);

// Get the child product's ID
$childProductId = $selectedOption['value'];

// Load the child product
$childProduct = $item->getProduct()->getTypeInstance()->getUsedProductById($childProductId);

// Access the child product's name
$childProductName = $childProduct->getName();

$logger->info('Child Product Name: ' . $childProductName);

You should be able to do the following

$item = $observer->getEvent()->getData('quote_item');
if ($item->getHasChildren() ) {
    foreach ($item->getChildren() as $child)  $logger->info('item: ' . $child->getName());
}
