Delete Magento 2 product custom option programmatically

Question

I created magento 2 custom option programmatically like this:

 $options[] = [
 'title' => 'cthulu',
 'type' => 'field',
 'is_require' => false,
 'sort_order' => 2,
 'price' => 0,
 'price_type' => 'fixed',
 'sku' => 'cthulu',
 'max_characters' => 20,
 ];
 $options[] = [
 'title' => 'comment',
 'type' => 'field',
 'is_require' => false,
 'sort_order' => 2,
 'price' => 0,
 'price_type' => 'fixed',
 'sku' => 'comment',
 'max_characters' => 50,
 ];
foreach ($options as $option) {
 $customOption = $this->customOptionFactory->create(['data' => $option]);
 $customOption->setProductSku($product->getSku());
 $customOptions[] = $customOption;
 }
 $product->setCanSaveCustomOptions(true)
 ->setOptions($customOptions)
 ->setHasOptions(true)
 ->save();

the custom option save successfully, now i want to delete the custom option programmatically, is there a way to do this?

Answer 1

To simply remove all the custom options from all products use the below one time script. Add it in any of your controller.

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
 $products = $objectManager->get('\Magento\Catalog\Model\Product')->getCollection();
 foreach ($products as $product) {
 $product = $objectManager->get('\Magento\Catalog\Model\Product')->load($product->getId());
 if ($product->getOptions()) {
 foreach ($product->getOptions() as $opt) {
 $opt->delete();
 }
 //$product->setHasOptions(0)->save();
 } else {
 echo $product->getId();
 }
 }
 echo 'DONE';

This is one time hitting script, so no need for not using Object Manager

<?php
 namespace Test\Module\Block;
 use Magento\Catalog\Api\ProductRepositoryInterface;
 class Product extends \Magento\Framework\View\Element\Template
 {
 protected $productRepository; 
 public function __construct(
 \Magento\Framework\App\Action\Context $context,
 ProductRepositoryInterface $productRepository
 ) {
 parent::__construct($context);
 $this->productRepository = $productRepository;
 }
}

now you can delete option like,

$product = $this->productRepository->getById(1);// replace with your product Id

if($product->getOptions() != "){
 foreach ($product->getOptions() as $opt){
 $opt->delete();
 }
 $product->setHasOptions(0)->save();
 }
