Magento 2：允许客户在购物车上编辑自定义选项

Question

我正在尝试添加允许客户编辑选项的功能。

我创建了一个模块供应商/组件。 这是加载自定义选项并选择，但是没有获得用户选择的选项。

我想知道如何接收所选选项并检查是否选择了该选项。 目前，Select.php中的这一行没有收到任何内容，变量$ checked为null。

$configValue = $this->getProduct()->getPreconfiguredValues()->getData('options/' . $_option->getId());

在Vendor / COptions \ view \ frontend \ templates \ cart \ item \ default.phtml中：

 <?php $selectedOptions = $block->getSelectedOptionList(); ?>
 <?php //$_options = Mage::helper('core')->decorateArray($block>getOptions())
    $_options =  $block->getOptions() ?>  
  <?php if ($_options AND count($_options)):?>
    <dl>
   <?php foreach($_options as $_option): ?>
  <?php echo $this->getOptionHtml($_option) ?>
   <?php endforeach; ?>
   </dl>
  <?php endif; ?>

在Vendor \ COptions \ Helper \ Rewrite \ Product：

中

public function getCustomOptions(\Magento\Catalog\Model\Product\Configuration\Item\ItemInterface $item, $simple="")
{

    $product = $item->getProduct();
    $coptions = [];
    $coptions = $product->getOptions();
    $options = array();

   if ($coptions) { 
   foreach ($coptions as $option) {
   $itemOption = $item->getOptionByCode('option_' . $option->getId());

           /** @var $group \Magento\Catalog\Model\Product\Option\Type\DefaultType */
                  $group = $option->groupFactory($option->getType())
                      ->setOption($option)
                      ->setConfigurationItem($item)
                      ->setConfigurationItemOption($itemOption);



                  if ('file' == $option->getType()) {
                      $downloadParams = $item->getFileDownloadParams();
                      if ($downloadParams) {
                          $url = $downloadParams->getUrl();
                          if ($url) {
                              $group->setCustomOptionDownloadUrl($url);
                          }
                          $urlParams = $downloadParams->getUrlParams();
                          if ($urlParams) {
                              $group->setCustomOptionUrlParams($urlParams);
                          }
                      }
                  }


  if($simple == "Y"){


    array_push($options, $itemOption['value']);
  }else{
                  $options[] = [
                      'label' => $option->getTitle(),

}
}
