How to save multiselect values programmtically in magento 2?

Question

I am unable to save product multiselect values .I tried both ways Here is code

Way 1

$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); $_product = $objectManager->create('Magento\Catalog\Model\Product'); $_product->load(757); $string = '5641,5642'; // option ids $_product->setData('multi_select_color_code',$string); $_product->save();

Way 2:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); $_product = $objectManager->create('Magento\Catalog\Model\Product'); $_product->load(757); $array= array('5641','5642'); // option ids $_product->setData('multi_select_color_code',$array); $_product->save();

Try this code

protected $productRepository; public function __construct( ......................................................... \Magento\Catalog\Model\ProductRepository $productRepository, ......................................................... ) { ......................................................... $this->productRepository = $productRepository; ......................................................... } public function SetProductAttribute() { $productId = "757"; $attributeValue = '5641,5642'; $product = $this->productRepository->getById($productId); $product->setCustomAttribute('multi_select_color_code', $attributeValue); //$product->setData('multi_select_color_code', $attributeValue); $this->productRepository->save($product); }

I Hope This Helps You

thank you for your answer. After digging into database table catalog_product_entity_varchar .my data was storing as store id 1 so thats why it did not reflect on admin products. after putting $product->setStoreId(0); it reflects the data in admin as well as frontend.

I have the class below working at my end. In other words, way 2 is the way to go but this is assuming your custom attribute has the right setup. Also, you may notice below I am setting the area code to adminhtml

 class SaveProductAttribute extends Command { /** * @var ProductRepositoryInterface */ private $productRepository; /** * @var \Magento\Framework\App\State */ private $state; public function __construct( ProductRepositoryInterface $productRepository, \Magento\Framework\App\State $state, $name = null) { parent::__construct($name); $this->productRepository = $productRepository; $this->state = $state; } public function configure() { $this->setName('mbs:product_multiselect:save') ->setDescription('Save product multiselect value'); $this->addArgument('sku', InputArgument::REQUIRED); } protected function execute(InputInterface $input, OutputInterface $output) { $this->initialiseAreaCode(); $product = $this->productRepository->get($input->getArgument('sku')); $output->writeln(sprintf('sku: %s has activity: %s', $input->getArgument('sku'), $product->getData('activity')) ); $product->setData('activity', [5432]); $this->productRepository->save($product); $output->writeln('attribute saved'); } private function initialiseAreaCode(): void { try { $this->state->setAreaCode(Area::AREA_ADMINHTML); } catch (\Exception $e) { } }
