How to set a product's custom attribute on save? I have used the event/observer way but nothing works.

Official method should work, but Not

The official method setCustomAttribute($attributeCode, $attributeValue) below should work but NOT because the official bug https://github.com/magento/magento2/issues/4703.

The bug doesn't fix yet in version 2.2.3.

$product = $this->productRepository->getById($productId);
$product->setCustomAttribute($attributeCode, $attributeValue);
$this->productRepository->save($product);

Temporary method

After many debug and tries, I found the method $product->setData($attributeCode, $attributeValue) below could set custom attribute successfully, it is a temporary method.

Hope it could help you. Any better way is welcome to post :)

$product = $this->productRepository->getById($productId);
$product->setData($attributeCode, $attributeValue);
$this->productRepository->save($product);

  • This does not work for me using Magento 2.3.0. The only way I was able to get it was $product->getResource()->saveAttribute($product, $attributeValue); Very frustrating lol – quickshiftin Sep 12 '19 at 14:26

    $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); // instance of object manager
            $product = $objectManager->create('\Magento\Catalog\Model\Product');

            $prod = $product->loadByAttribute('sku', $sku);
$prod->setCustomattribute($value); // name of your custom attribute
$prod->save();

Rather using the setcustomattribute function you can just use this: Suppose your attribute code is inbound.

$product = $this->productRepository->getById($productId);
$product->setInbound($attributeValue);
$this->productRepository->save($product);
