I have following code, In which I am fetching attribute values for child and parent products:

 public function setAttributeValues(array $products)
        $this->values = [];
        foreach ($products as $product) {
            $attributes = $product->getAttributes();
            foreach ($attributes as $attribute) {
                $value = $attribute->getFrontend()->getValue($product);
                if (empty($value)) {
                    $value = $product->getData($attribute->getAttributeCode());
                $this->setValue($attribute->getId(), $product->getId(), $value);

            if ($product->getTypeID() == Configurable::TYPE_CODE) {
                $children = $product->getTypeInstance()->getUsedProducts($product);
                foreach ($children as $child) {
                    $childAttributes = $child->getAttributes();

                    foreach ($childAttributes as $childAttribute) {
                        $value = $childAttribute->getFrontend()->getValue($child);
                        print_r($value); // Facing attribute issue here
                        $this->setValue($childAttribute->getId(), $child->getId(), $value);

I am getting null values for some attributes. In if ($product->getTypeID() == Configurable::TYPE_CODE) {} part. I've tried multiple logic to fetch attribute value but none of them worked for me. Also, I've verified that attribute value are set for the the particular product.

Any help would be really appreciated.

You can use a collection to fetch the attributes of child products



protected $productCollectionFactory;

public function __construct(
    CollectionFactory $productCollectionFactory
) {
    $this->productCollectionFactory = $productCollectionFactory;

public function getChildProductAttributes($configurableProduct)
    $childIds = $configurableProduct->getTypeInstance()->getChildrenIds($configurableProduct->getId());
    $childIds = array_shift($childIds);

    $collection = $this->productCollectionFactory->create()
        ->addFieldToFilter('entity_id', ['in' => $childIds]);

    foreach ($collection as $childProduct) {
        $attributeValue = $childProduct->getData('attribute_code');
        // Process attribute value

Thank You!

your issue is the product attribute configuration Those whose values is not printing you have to go to product attributes open the attribute and select YES in "Used in Product Listing"

Please don't forget to clear cache after changing value of attribute That will solve your issue
