Magento - 在脚本中累积自定义选项

Question

在下面的脚本中，我迭代了一堆产品。对于其中每一个，我想添加一个自定义选项“Eskestørrelse”。在第一个产品上就像一个魅力，但是对于以下产品，以前产品的自定义选项以某种方式保留，并且该产品最终将具有多个自定义选项。

例如 - 第 10 个产品将有 10 个自定义选项，这些选项是为产品 1、2、3、... 生成的选项 10.

我做错了什么？

这是脚本（如果您更喜欢 Pastie，请参阅 http://pastie.org/1243529）、自定义选项和产品以粗体保存：

$categoryId = 128;
$storeId = 4;
$cwd = getcwd();
chdir($launchdir);
echo "Entered $launchdir...\n";

require_once('includes/config.php');
require_once('app/Mage.php');

try {

  $mageObj = Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);;

  $category = Mage::getModel('catalog/category')->load($categoryId);
  $products = $category->getProductCollection()->addStoreFilter($storeId)->addAttributeToSelect('*');

  echo "Found " . count($products) . " products in category #{$categoryId} + store #{$storeId}...\n";

  $nodesc = array();
  $n = 0;
  foreach($products as $product) {
    $sku = $product->getSku();
    $desc = $product->getDescription();
    $shortdesc = $product->getShortDescription();
    $price = $product->getPrice();

    $matches = array();
    if (preg_match('/[Ee]ske med ([0-9]+)/', $desc, $matches)==0) {

      $nodesc[] = $product;

    }
    else {
      $product = Mage::getModel('catalog/product')->load($product->getId());

      $halfqty = (int)($matches[1] / 2);
      $halfpriceExact = ($price / 2) * 1.1;
      $halfprice = ceil($halfpriceExact/10) * 10;

      $pricediff = round(($halfprice / ($price / 2)) * 100) - 100;
      $savepct = round(($halfprice*2 - $price)/($halfprice*2)*100);

      echo "{$sku}: quantity ({$matches[1]}, {$halfqty}), price ({$price}, {$halfprice} ({$halfpriceExact}), half +{$pricediff}%), savepct {$savepct}% \n";

      $newdesc = preg_replace('/([Ee])ske med [0-9]+/', "$1ske med {$halfqty} eller {$matches[1]} ", $desc);
      $newshortdesc = preg_replace('/([Ee])ske med [0-9]+/', "$1ske med {$halfqty} eller {$matches[1]} ", $shortdesc);
      $product->setPrice($halfprice);
      $product->setDescription($newdesc . "\n\n<b>PS! </b>Du sparer $savepct% ved å kjøpe den største esken ({$matches[1]} stk).");
      $product->setShortDescription($newshortdesc);

      // figure out options
      $newopts = array();
      $newopts[] = array(
        'title' => 'Eskestørrelse',
        'type' => 'drop_down',
        'previous_type' => null,
        'previous_group' => 'select',
        'is_require' => 1,
        'is_delete' => null,
        'sort_order' => 1,
        'values' => array(
          array(
            'option_type_id' => -1,
            'is_delete' => null,
            'title' => "Eske med {$matches[1]} stk.",
            'price' => ($price - $halfprice),
            'price_type' => 'fixed',
            'sku' => "-{$matches[1]}",
            'sort_order' => '1'
          ),
          array(
            'option_type_id' => -1,
            'is_delete' => null,
            'title' => "Eske med {$halfqty} stk.",
            'price' => 0.00,
            'price_type' => 'fixed',
            'sku' => "-{$halfqty}",
            'sort_order' => '2'

          )
        )
      );

      if ($product->getOptionsReadonly()) {
        echo "READONLY options, cant save...\n";
      }
      else {
        $product->setProductOptions($newopts);
        $product->setCanSaveCustomOptions(true);
        $product->save();

        $n++;
        if ($n==2) die('temp stop');
      }
    }
    $options = null;
    $product = null;
  }

  echo "SUMMARY: " . count($products) . " products. " . count($nodesc) . " descriptions with no match. \n";
  foreach ($nodesc as $product) {
    echo "UNMATCHED: " . $product->getSku() . "\n";
  }

}
catch (Exception $e) {
  echo "Failed with exception " . $e . "\n";
}

chdir($cwd);
echo "Returned to $cwd...\n";
return;

经过几个小时和深入研究 Magentos 模型类后，我解决了这个问题。似乎产品选项是用单例模式设计的。

无需重新加载第 37 行中的产品：

$product = Mage::getModel('catalog/product')->load($product->getId());

……这只是解决此问题的绝望尝试。我应该做的是重置 Magentos 单例 Product_Option 实例中设置的多个选项。将第 37 行替换为以下行可以解决问题：

Mage::getSingleton('catalog/product_option')->unsetOptions(); // forget me and Magento will hate you

希望这可以避免其他人的挫败感。 ;)
