how to set product attribute value programmatically magento2

Question

I've made a product attribute "inbound" and it has two options, yes and no, I have assigned "no" to it initially but when I'm checking out I'm using an observer to change its value to "yes" programmatically if product quantity less then 100, everything is working fine but can't able to change its value to yes.

Thanks in advance

Answer 1

Thanks everyone for the answers, it really helps, i got the right way to do that, rather using setcustomasttribute function cause its throwing errors.you can just simply do this.

$product = $this->productRepository->getById($productId);
$product->setInbound($attributeValue);
$product->setData('store_id', 0);//remember to set store id other wwise data 
mismatch occurs//
$this->productRepository->save($product);

Here is how you can set attribute value $product = $this->productRepository->getById($productId); $product->setData($attributeCode, $attributeValue); $this->productRepository->save($product);

• nihal malik: you are using $this->productRepository->getById($productId); so it means i can use Magento\Catalog\Model\ProductRepository dependency ??
• Hamendra Sunthwal: Yes you can set product attribute , by loading product's object and then use set method to set attribute value and then save.
• Hamendra Sunthwal: Try and let us know if its helpful and works , give upvote on the answer if it works 4 you, so it will help to others in Magento community.
• Hamendra Sunthwal: Worked or not ?
• nihal malik: hey there, my attribute is multiselect and its adding a new row for the attribute.if a product already has a attribute value selected like "no" if i tried to make it "yes" using your code its working but its not eliminating the "no" it sets both values yes and no for the product
