在magento的主页上禁用带有占位符图像的产品 [英] Disable products with placeholder image on home page in magento

问题描述

我使用随机代码在我们的magento商店的主页上显示不同类别的产品.这完美地工作.现在，我想排除所有仅具有占位符图像的产品，使其不显示在主页上.我用以下代码尝试过:

I use a random code to display products from different categories on the home page on our magento powered shop. This works perfectly. Now I would like to exclude all the products which only have a placeholder image from showing up on the home page. I tried it with the following code:

class Mage_Catalog_Block_Product_List_Random extends Mage_Catalog_Block_Product_List
{
    protected function _getProductCollection()
    {
        if (is_null($this->_productCollection)) {
            $categoryID = $this->getCategoryId();
            if($categoryID)
            {
              $category = new Mage_Catalog_Model_Category();
              $category->load($categoryID); // this is category id
              $collection = $category->getProductCollection();
            } else
            {
              $collection = Mage::getResourceModel('catalog/product_collection');
            }
            Mage::getModel('catalog/layer')->prepareProductCollection($collection);
            $collection->getSelect()->order('rand()');
            $collection->addStoreFilter();
            $numProducts = $this->getNumProducts() ? $this->getNumProducts() : 3;
            $collection->setPage(1, $numProducts)->load();

            $collection->addAttributeToFilter(
                array('attribute' => 'small_image', 'eq' => ''),
                array('attribute' => 'small_image', 'eq' => 'no_selection')
            );

            $this->_productCollection = $collection;
        }
        return $this->_productCollection;
    }
} 

但这不起作用，只有占位符图像的产品仍然会显示.

But this doesn't work and the products with only the placeholder image do still show up.

任何帮助将不胜感激.

谢谢，丹尼尔

推荐答案

您要在已加载收藏集 之后添加"small_image"过滤器，因此您的过滤器不会不再影响收藏了.

You're adding the 'small_image' filter after the collection already has been loaded, so your filter will not affect the collection anymore.

除此之外，您的 OR 过滤器在我看来很奇怪.假设"no_selection"也是一些占位符图像，那么您的过滤器会接受占位符图像，我认为您想在其中拒绝.

Other than that your OR filter looks odd to me. Assumed 'no_selection' is some placeholder image too, then your filter does accept placeholder images, where I think you want to decline them.

尝试改用AND过滤器:

Try to use an AND filter instead:

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