在循环中创建捆绑产品

Question

我有一个循环以编程方式创建多个捆绑产品。新包的创建工作正常，但如果我有一个现有包并尝试添加/删除选项，它会失败。

如果我第一次运行我的导入代码，就会创建包。第二次，所有选项都将被删除，只有数组的最后一个包有它的选项集。

$ids = [8663,8665,8664];
foreach ($ids as $id) {
    createBundle($id);
}

function createBundle($id)
{
    Mage::unregister('product');

    try {
        $bundleProduct = Mage::getModel('catalog/product')->load($id);
        Mage::register('product', $bundleProduct);

        // try to get already assigned options and remove them all
        $selectionCollection = $bundleProduct->getTypeInstance(true)->getSelectionsCollection(
            $bundleProduct->getTypeInstance(true)->getOptionsIds($bundleProduct), $bundleProduct
        );

        // remove assigned options
        // works fine
        foreach ($selectionCollection as $option) 
        {
            $optionModel = Mage::getModel('bundle/option');
            $optionModel->setId($option->option_id);
            $optionModel->delete();
        }

        $bundleOptions = array(
            '0' => array( //option id (0, 1, 2, etc)
                'title' => 'item01', //option title
                'option_id' => '',
                'delete' => '',
                'type' => 'select', //option type
                'required' => '1', //is option required
                'position' => '0' //option position
            ),
            '1' => array(
                'title' => 'item02',
                'option_id' => '',
                'delete' => '',
                'type' => 'multi',
                'required' => '1',
                'position' => '0'
            )
        );

        $bundleSelections = array();
        $bundleSelections = array(
            '0' => array( //option ID
                '0' => array( //selection ID of the option (first product under this option (option ID) would have ID of 0, second an ID of 1, etc)
                    'product_id' => 8631, //id of a product in selection
                    'delete' => '',
                    'selection_price_value' => '0',
                    'selection_price_type' => 0,
                    'selection_qty' => 10,
                    'selection_can_change_qty' => 0,
                    'position' => 0,
                    'is_default' => 1
                )
            ),
            '1' => array( //option ID
                '0' => array(
                    'product_id' => 8630,
                    'delete' => '',
                    'selection_price_value' => '0',
                    'selection_price_type' => 0,
                    'selection_qty' => 1,
                    'selection_can_change_qty' => 0,
                    'position' => 0,
                    'is_default' => 1
                )
            )
        );

        // flags for saving custom options/selections
        $bundleProduct->setCanSaveCustomOptions(true);
        $bundleProduct->setCanSaveBundleSelections(true);
        $bundleProduct->setAffectBundleProductSelections(true);

        // setting the bundle options and selection data
        $bundleProduct->setBundleOptionsData($bundleOptions);
        $bundleProduct->setBundleSelectionsData($bundleSelections);

        $bundleProduct->save();
        $bundleProduct->setData(array());
        return $bundleProduct->getId();

    } catch (Exception $e) {
        Mage::log($e->getMessage());
        echo $e->getMessage();
    }
}

那么，我怎样才能得到这份工作呢？如果我删除了删除选项的部分，那么每次执行代码时都会创建新的空选项（这是错误的）。

更新：我发现，如果我三次运行脚本，每个捆绑包都具有另一个产品 ID，则这些包已正确创建/更新。所以问题一定是在单个请求中循环执行。

最后，我自己发现了。这部分贴出的代码：

    // try to get already assigned options and remove them all
    $selectionCollection = $bundleProduct->getTypeInstance(true)->getSelectionsCollection(
        $bundleProduct->getTypeInstance(true)->getOptionsIds($bundleProduct), $bundleProduct
    );

    // remove assigned options
    // works fine
    foreach ($selectionCollection as $option) 
    {
        $optionModel = Mage::getModel('bundle/option');
        $optionModel->setId($option->option_id);
        $optionModel->delete();
    }

似乎只删除了选项的选择部分。要删除完整选项，我必须这样做：

    // try to get already assigned options and remove them all
    $optionCollection = $_product->getTypeInstance(true)->getOptionsCollection($_product);

    // remove assigned options
    foreach ($optionCollection as $option) 
    {
        $option->delete();
    }
