过滤带有图像的产品的Magento产品系列

Question

我有一个产品系列，我从一个可配置的产品中获得，我想过滤该系列只包括附有图像的产品。我该怎么做？

代码看起来像这样：

$configurableProduct = $this->getConfigurableProduct();
$childProducts = $configurableProduct->getTypeInstance()->getUsedProductCollection();

// add some filter here to get only products with images
$childProducts->addAttributeToFilter( /* what goes here? */ );    

foreach( $childProducts as $product ) {
   ...
}

感谢任何帮助。谢谢！ 乔

Answer 1

$this->_productCollection->addAttributeToFilter('small_image',array('notnull'=>'','neq'=>'no_selection'))

Answer 2

也适用于此：

$collection->addAttributeToFilter('small_image',array('notnull'=>'','neq'=>'no_selection'));
