php - 以编程方式更新 bundle 产品 magento？

Question

我在 magento 中创建了一个脚本，用于创建 bundle 产品并且运行良好。但我还想用新的精选产品更新创建的 bundle 产品。这是我的代码，但无法正常工作:

public function updateBundleProduct($pro_id,$cPrdcts){     $bundleProduct = Mage::getModel('catalog/product');     $bundleProduct->load($pro_id);     $bundleProduct->setName('test product bundle bundlea');     $bundleSelections = array();          $bundleSelections = array(               '0' => array( //option ID                 '0' => array(                     'product_id' => '70',                     'delete' => '',                     'selection_price_value' => '10',                     'selection_price_type' => 0,                     'selection_qty' => 1,                     'selection_can_change_qty' => 0,                     'position' => 0,                     'is_default' => 1,                     'selection_id' => 71,                     'option_id' => 14                 ),                  '1' => array(                     'product_id' => '84',                      'delete' => '',                     'selection_price_value' => '10',                     'selection_price_type' => 0,                     'selection_qty' => 1,                     'selection_can_change_qty' => 0,                     'position' => 0,                     'is_default' => 1,                     'selection_id' => 72,                     'option_id' => 14                      )             )     //get all selected products list and data          );     $bundleOptions = array();         $bundleOptions = array(             '0' => array(                 'title' => 'All Items2',                 'option_id' => 14,                 'delete' => '',                 'type' => 'multi',                 'required' => '1',                 'position' => '1'             )         );         $bundleProduct->setData('_edit_mode', true);         //flags for saving custom options/selections         $bundleProduct->setCanSaveCustomOptions(true);         $bundleProduct->setCanSaveBundleSelections(true);         $bundleProduct->setAffectBundleProductSelections(true);         //registering a product because of Mage_Bundle_Model_Selection::_beforeSave         Mage::register('product', $bundleProduct);         //setting the bundle options and selection data         $bundleProduct->setBundleOptionsData($bundleOptions);         $bundleProduct->setBundleSelectionsData($bundleSelections);      // echo '
'.print_r($bundleProduct,true).'
 ';导出;         $bundleProduct->保存();}

但是我没有添加产品项目，而是删除了我之前的选项。

研究了一段时间，我发现它是certainly common构建一些产品信息数组并从这些数组“手动构建” bundle 产品，就像您所做的那样。

这很令人惊讶，而且看起来并不复杂，所以是时候检查一下 Magento 在使用标准 Magento 管理面板时如何处理更新了。事实上，Magento 实际上使用了相同的技术来构建数据数组。您可以编辑 bundle 产品，启动 Web 控制台，并在保存时查看发布的数据。

Magento bundle 产品由称为选项的组组成，其中包含称为选择的产品。

要使用新选择更新一些 bundle 产品选项，您可以像这样创建一个数组:

$selectionData = array(
    //'selection_id' => 'not set, so Magento will create a new one',
    'option_id' => $option->getId(),
    'product_id' => $product->getId(),
    'delete' => '',
    'selection_price_value' => '0.00',
    'selection_price_type' => '0',
    'selection_qty' => '1.0000',
    'selection_can_change_qty' => '1',
    'position' => '0',
);

数组结构是在 Magento 管理面板中更新 bundle 产品时发布的内容的副本。

然后您可以使用该数据构建新的选择，如 app/code/core/Mage/Bundle/Model/Product/Type.php

中所做的那样

$resource = Mage::getResourceModel('bundle/bundle');

$bundleProduct = YOUR_BUNDLE_PRODUCT;

// app/code/core/Mage/Bundle/Block/Adminhtml/Catalog/Product/Edit/Tab/Bundle/Option.php
$optionCollection = $bundleProduct->getTypeInstance(true)->getOptionsCollection($bundleProduct);

$selectionCollection = $bundleProduct->getTypeInstance(true)->getSelectionsCollection(
    $bundleProduct->getTypeInstance(true)->getOptionsIds($bundleProduct),
    $bundleProduct
);

$options = $optionCollection->appendSelections($selectionCollection);

// needed because of app/code/core/Mage/Bundle/Model/Selection.php:73
Mage::register('product', $bundleProduct);

// process each option
foreach ($options as $option) {
    $selections = $option->getSelections();

    // process each selection
    foreach ($selections as $selection) {
        $usedProductIds = array();

        $productCollection = YOUR_PRODUCT_COLLECTION;

        foreach ($yourProductCollection as $product) {

            $selectionData = array(
                //'selection_id' => 'not set, so Magento will create a new one',
                'option_id' => $option->getId(),
                'product_id' => $product->getId(),
                'delete' => '',
                'selection_price_value' => '0.00',
                'selection_price_type' => '0',
                'selection_qty' => '1.0000',
                'selection_can_change_qty' => '1',
                'position' => '0',
            );

            // app/code/core/Mage/Bundle/Model/Product/Type.php:315
            $selectionModel = Mage::getModel('bundle/selection')
                ->setData($selectionData)
                ->setOptionId($option->getId())
                ->setParentProductId($bundleProduct->getId());

            $selectionModel->isDeleted((bool)$selectionData['delete']);
            $selectionModel->save();

            $selectionData['selection_id'] = $selectionModel->getSelectionId();

            if ($selectionModel->getSelectionId()) {
                $excludeSelectionIds[] = $selectionModel->getSelectionId();
                $usedProductIds[] = $selectionModel->getProductId();
            }
        }

        $resource->dropAllUnneededSelections($bundleProduct->getId(), $excludeSelectionIds);
        $resource->saveProductRelations($bundleProduct->getId(), array_unique($usedProductIds));
    }
}

Mage::unregister('product');

也很有可能对其进行调整以添加 bundle 选项。我建议查看上面评论中提到的文件。
