I have work on Custom Module. In Our Module I had use

    <observer name="add_custom_option" instance="Namespace\Modulename\Observer\AddCustomOption" />
</event>

In observer i Had Generate Product Custom Option Programmatically

            $product->setHasOptions(1);
            $product->setCanSaveCustomOptions(true);
            foreach ($options as $arrayOption) {
                $isHasOptions = $product->getTypeInstance()->hasOptions($product);

                 $option = \Magento\Framework\App\ObjectManager::getInstance()
                        ->create('\Magento\Catalog\Model\Product\Option')
                        ->setProductId($product->getId())
                        ->setStoreId($product->getStoreId())
                        ->addData($arrayOption);

                $this->customoptionOperation($option, 'save');
                $product->addOption($option);
                //$product->save();
            }

i have use this code for generate Product custom Option.

//$product->save();

i had comment this code because it provide me Error

But Custom Option Not Appears in Front-end

But When i have save product second time after saving product the Options are Appears in Front-end Without need Run any Commands.

I Need Solution to save Product One time and Get Product Option Front End

Answer 1

You can try using a Product Repository Magento\Catalog\Api\ProductCustomOptionRepositoryInterface

Like this:

$product->setHasOptions(1);
$product->setCanSaveCustomOptions(true);
foreach ($options as $arrayOption) {
    $isHasOptions = $product->getTypeInstance()->hasOptions($product);

    $option = \Magento\Framework\App\ObjectManager::getInstance()
                ->create('\Magento\Catalog\Api\ProductCustomOptionRepositoryInterface')
                ->setProductId($product->getId())
                ->setStoreId($product->getStoreId())
                ->addData($arrayOption);

    $this->customoptionOperation($option, 'save');
    $product->addOption($option);
    $product->save();
}

Save Product Using ProductRepositoryInterface :-

$option = $this->_objectManager->create(\Magento\Catalog\Model\Product\Option::class)
        ->setProductId($_product->getId())
        ->setStoreId($_product->getStoreId())
        ->addData($arrayOption);
    $option->save();
    $product->addOption($option);
    $productRepo = $this->_objectManager->create('Magento\Catalog\Api\ProductRepositoryInterface');
    $productRepo->save($product);
