如何检查产品是否为简单产品

试试这个

$attributeSetModel = Mage::getModel("eav/entity_attribute_set")->load($product->getAttributeSetId());
$attributeSetName  = $attributeSetModel->getAttributeSetName();

$parentIds = Mage::getResourceSingleton('catalog/product_type_configurable')->getParentIdsByChild($product->getId());

if ($product->getTypeId() == 'simple' && empty($parentIds) && $attributeSetName == 'Default') {
    echo "This is a simple product with no parent configurable product in the 'Default' attribute set";
};

<?php if( $_product->getTypeId() == 'simple' ): ?>
//your code for simple products 
<?php endif; ?>

我希望,你想要 simple collection filter with default attribute 它们是 not in configurable products child Simple Product .

然后首先获取默认属性集id

 $entityType = Mage::getModel('catalog/product')->getResource()->getEntityType();
 $collection = Mage::getResourceModel('eav/entity_attribute_set_collection')
            ->setEntityTypeFilter($entityType->getId());
$collection->addFieldToFilter('attribute_set_name','Default');
$attrbuteSetId= $collection->getFirstItem()->getId();

过滤后产品 Collection with simple product type and of non default Attribute set .

$productCollection=Mage::getModel('catalog/product')->getCollection()
                        ->addAttributeToFilter('type_id','simple')
                        ->addAttributeToFilter('attribute_set_id',array('nin'=>$attrbuteSetId));

然后取出 Simple product ids which are used in Configurable product .

$select = Mage::getSingleton('core/resource')->getConnection('core_read')
        ->select()
        ->from('catalog_product_super_link', array('product_id'))
        ->group('product_id');
$resource = Mage::getSingleton('core/resource');
$readConnection = $resource->getConnection('core_read');
$results = $readConnection->fetchAll($select);

现在是最后的集合

$productCollection->addAttributeToFilter('entity_id',array('nin'=>$results));
