php - 过滤带有图像的产品的 Magento 产品系列

Question

我有一个从可配置产品中获取的产品系列，我想过滤该系列以仅包含附有图像的产品。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

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