Question

我是magento的新手。基本上，我想将多个产品分配给多个类别。我已经关注this post并且我已经完成了以下可正常工作的代码：

   $collection = Mage::getModel('catalog/product')->getCollection();//my coustom collection
        $categorys_ids = array(1,2,3,4,5);//Array of ids etc 
        if ($categorys_ids != NULL && $collection->getData()!= NULL)
            {
                foreach ($collection as $product) 
                {
                        $categories_pd = $product->getCategoryIds();                              
                        $product->setCategoryIds(array_merge($product->getCategoryIds(),array($categorys_ids)));
                        $product->save();
                }
            }

现在，主要问题是，当我为产品分配设置类别ID时，需要花费大量时间。我有200个产品，这需要两分钟左右，这是很多时间。

我想知道是否有一种方法可以为产品阵列分配类别，而不是将产品分配到类别或可以优化的东西，花费更少的时间。

Answer 1

以下是如何将多个产品分配到某个类别并与现有产品合并的方法该示例适用于一个类别，但您可以将其转换为循环以使其更有效。

$categoryId = 6; 
$category = Mage::getModel('catalog/category')->setStoreId(Mage_Core_Model_App::ADMIN_STORE_ID)->load($categoryId);
//get the current products
$products = $category->getProductsPosition();
//now attach the other products.
$newProductIds = array(1,2,3,4,5);
foreach ($newProductIds as $id){
    $products[$id] = 1;//you can put any other position number instead of 1.
}
//attach all the products to the category
$category->setPostedProducts($products);
//save the category.
$category->save();

如果您想要更快的方法，可以在表catalog_category_product中直接插入完成后，请确保重新索引。

我是这样做的，使用了较新PHP版本的一些快速数组管理功能：

<?php
require_once '../../app/Mage.php';
Mage::app();
Mage::app()->setCurrentStore(Mage::getModel('core/store')->load(Mage_Core_Model_App::ADMIN_STORE_ID));
$storeCode = Mage::app()->getStore()->getStoreId();

function addProductsToCategoryId($mergeProductIds, $categoryId, $storeCode) {
    // load the $category by $categoryId
    $category = Mage::getModel('catalog/category')->setStoreId($storeCode)->load($categoryId);
    // build a flipped array of two merged arrays (1) array keys from flipped $mergeProductIds, (2) array keys from product_id keyed array in $category
    $categoryProductIds = array_flip(array_merge(array_keys(array_flip($mergeProductIds)),array_keys($category->getProductsPosition())));
    // combine array_keys from resulting merge with a matched index array filled with '0'
    // THIS resets position of product within category, change this logic if desired
    $categoryProductIds = array_combine(array_keys($categoryProductIds), array_fill(0, count($categoryProductIds), '0'));

    $category->setPostedProducts($categoryProductIds);
    $category->save();

    // optional
    // return $categoryProductIds;
}

// optional array of category IDs to test against for nin (not in) or in a find_in_set array test
// in the optional example line below, nin (not in) is used
$categoryIds = array(5,8,9,10,11,12,45,46);

$collectionIds = Mage::getModel('catalog/product')->getCollection()
    ->setStoreId($storeCode)
    // optional inclusion of join for category_id
    ->joinField('category_id', 'catalog/category_product', 'category_id', 'product_id = entity_id', null, 'left')
    // optional logic to only gather ids that are, or are not in a given categoryIds array, nin (not in) is shown in example
    // ->addAttributeToFilter('category_id', array('nin' => array('finset' => $categoryIds)))
    // optional line to test whether product is associated to ANY category
    ->addAttributeToFilter('category_id', array('null' => true))
    // example qualifiers to affect gathered IDs
    ->addAttributeToFilter('sku', array('like' => 'M-H%'))
    ->addAttributeToFilter('sku', array('nlike' => '%E'))
    ->addAttributeToFilter('sku', array('nlike' => '%E#'))
    ->addAttributeToFilter('sku', array('nlike' => '%Euro'))
    ->addAttributeToFilter('sku', array('nlike' => '%Euro#'))
    ->getAllIds()
    ;

// if using a return value, you can set the results of this to a variable
// to perform further operations against the resulting data
addProductsToCategoryId($collectionIds, 8, $storeCode);

请注意，默认情况下，我的方法不会保留您设置的类别中的产品的任何位置。它会将所有位置设置回默认值“0”。

工作得很漂亮。之后需要重新索引，快速添加质量。代码有点复杂，因此在直接上下文注释中解释代码对我来说更有意义。

我在这里包含了很多可选的附加内容，但是它们都被标记为已完全解释。

以下代码对我有用：

include '../../app/Mage.php';
Mage::app('admin');
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);

$product_id = Mage::getModel("catalog/product")->getIdBySku($sku);
$product = Mage::getModel('catalog/product')->load($product_id);
$product->setCategoryIds($category_id);
$product->save();
