我正在循环浏览产品结果,如果产品是分组产品,我想获得该组中的所有产品。我这样做:

$products = Mage::getModel('catalog/product')
                    ->getCollection()
                    ->addAttributeToSelect('*');
foreach ($products as $product) {
    if ($product->getTypeId() == 'grouped'){
        // how do I now get associated products of $product?
    }
}

在:

/magento/app/design/frontend/base/default/template/catalog/product/view/type/grouped.phtml

你会看到他们使用它:

<?php 
    $_associatedProducts = $this->getAssociatedProducts();

由于该phtml文件的类型为Mage_Catalog_Block_Product_View_Type_Grouped,我们可以转到:

/magento/app/code/core/Mage/Catalog/Block/Product/View/Type/Grouped.php

并看到Mage_Catalog_Block_Product_View_Type_Grouped::getAssociatedProducts()执行此操作:

<?php
    $this->getProduct()->getTypeInstance()->getAssociatedProducts($this->getProduct());

因此,我们可以放心地假设$this->getProduct()返回一个产品对象,并将其替换为您的$product变量,如下所示:

<?php
    if ($product->getTypeId() == 'grouped'){
        // how do I now get associated products of $product?
        $associatedProducts = $product->getTypeInstance()->getAssociatedProducts($product);
    }

如果我要完全优化你的代码,我会这样写:

<?php
    $products = Mage::getModel('catalog/product')
        ->getCollection()
        ->addAttributeToFilter('type_id', array('eq' => 'grouped'));
    foreach ($products as $product) {
        $associatedProducts = $product->getTypeInstance()->getAssociatedProducts($product);
        // Do something with $associatedProducts
    }

或者,如果您只想获得相关产品的ID,可以使用以下方法(速度更快):

public function getAssociatedProductIds($groupedProductId)
{
    $coreResource = Mage::getSingleton('core/resource');
    $conn = $coreResource->getConnection('core_read');
    $select = $conn->select()
        ->from($coreResource->getTableName('catalog/product_relation'), array('child_id'))
        ->where('parent_id = ?', $groupedProductId);

    return $conn->fetchCol($select);
}

按类型获取产品:

$product = Mage::getModel('catalog/product')
   ->getCollection()
   ->addAttributeToFilter('type_id', array('eq' => 'grouped'))
   ->load();

$parentProductId = array();

foreach($product as $simpleProducts) {
  $simpleProducts->loadParentProductIds();
  array_push($parentProductId,$simpleProducts->getParentProductIds();
}
