Editing options on opencart order confirmation page?

Question

opencart

Good afternoon. Trying to do edit options on opencart 2.3 confirmation page.
Made the output of options by adding to the controller

$options_my = array();

      foreach ($this->model_catalog_product->getProductOptions($product['product_id']) as $option) {
        $product_option_value_data = array();

        foreach ($option['product_option_value'] as $option_value) {
          if (!$option_value['subtract'] || ($option_value['quantity'] > 0)) {
            if ((($this->config->get('config_customer_price') && $this->customer->isLogged()) || !$this->config->get('config_customer_price')) && (float)$option_value['price']) {
              $price = $this->currency->format($this->tax->calculate($option_value['price'], $product_info['tax_class_id'], $this->config->get('config_tax') ? 'P' : false), $this->session->data['currency']);
            } else {
              $price = false;
            }

            $product_option_value_data[] = array(
              'product_option_value_id' => $option_value['product_option_value_id'],
              'option_value_id'         => $option_value['option_value_id'],
              'name'                    => $option_value['name'],
              'image'                   => $this->model_tool_image->resize($option_value['image'], 50, 50),
              'price'                   => $price,
              'price_prefix'            => $option_value['price_prefix']
            );
          }
        }

        $options_my[] = array(
          'product_option_id'    => $option['product_option_id'],
          'product_option_value' => $product_option_value_data,
          'option_id'            => $option['option_id'],
          'name'                 => $option['name'],
          'type'                 => $option['type'],
          'value'                => $option['value'],
          'required'             => $option['required']
        );
      }

After inserting into ['products']
'options_my' => $options_my,
Everything is displayed fine, but how to actually edit them?
Judging by editing the quantity of goods, the request goes to the checkout method of the controller... Can anyone help with this? public function edit() {

Answer 1

All right.
Editing products in the controller/checkout/cart.php -> edit() method
Plus you will need to edit system/library/cart/cart.php -> update(
) options
2. From the controller, pass this to the basket library
3. It remains to add the request so that, in addition to the number, it also updates information about the options.
