我是 magento 的新手。基本上,我想将多个产品分配给多个类别。我已经关注了这篇文章并且我已经完成了以下代码,该代码运行良好:
$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();
}
}
现在的主要问题是,当我为产品分配设置类别 id 时,需要花费很多时间。我有 200 个产品,这需要两分钟左右的时间,这是一个很长的时间。
我想知道是否有一种方法可以将类别分配给产品数组,而不是将产品分配给类别或可以优化且花费更少时间的方法。
以下是如何将多个产品分配到一个类别并与现有产品合并。
该示例适用于一个类别,但您可以将其转换为循环以使其适用于更多类别。
$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,您可以直接在表中插入
catalog_category_product
。这是我的做法,使用较新 PHP 版本中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”。
做工精美。之后需要重新索引,快速批量添加。代码有点复杂,因此在这种情况下,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功能,但它们都被标记为这样并得到了充分的解释。
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();
