How to add field value while creating a simple product Programmatically in Magento 2?

Question

I have successfully created simple product Programmatically using magento 2.

But i have created a filed in back end and add that in product but how to fill that data when creating a product.

I have created my product by

$product = $this->productFactory->create();
                $product->setSku($productsku);
                $product->setName($productname);
                $product->setDescription($productname."Description3");
                $product->setShortDescription($productname."Short Description3");
                $product->setWebsiteIds([1]);
                $categories = ["3"];
                $product->setCategoryIds($categories);
                $product->setWeight(1);
                $product->setTypeId(\Magento\Catalog\Model\Product\Type::TYPE_SIMPLE);
                $product->setVisibility(\Magento\Catalog\Model\Product\Visibility::VISIBILITY_BOTH); // To make product visible in both catalog,search
                $product->setPrice($p);
                $product->setAttributeSetId(4); // Attribute set for products
                $product->setStatus(\Magento\Catalog\Model\Product\Attribute\Source\Status::STATUS_ENABLED);
                $product->setUrlKey($productsku);
                $product->setStockData(
                    array(
                        'use_config_manage_stock' => 0,
                        'manage_stock' => 1,
                        'is_in_stock' => 1,
                        'qty' => 1
                    )
                );
                $product = $this->productRepository->save($product);
                $product->save();

Like i have to add some custom data while creating a product Programmatically.How to do that ?

Any Help is appreciated.

Answer 1

Custom attributes values in magento 2 can be set and retrieved by

Getting Value getCustomAttribute('myattribute')->getValue() / getMyattribute()

Setting Value setCustomAttribute('myattribute', $value); / setMyattribute($value)
