Question

I’m working with Magento 1.7.0.2 and I’m trying to display a custom image from my products in a random product_list.

First of all I added the attribute to all my sets and set a placeholder image.
In the database I searched for *used_in_product_listing* and set it to 1.

This is my Product_List_Random Class:

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);
                $collection = $category->getProductCollection();
            } else { 
                $collection = Mage::getResourceModel('catalog/product_collection'); 
            }
            Mage::getModel('catalog/layer')->prepareProductCollection($collection);
            $collection->addAttributeToSelect('*');
            $collection->getSelect()->order('rand()');
            $collection->addStoreFilter();
            $numProducts = $this->getNumProducts() ? $this->getNumProducts() : 0;
            $collection->setPage(1, $numProducts)->load();

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

Here I tried to add $collection->addAttributeToSelect('*'); to get the url of the image in frontend.

This is what I tried so far in frontend:

$_productCollection=$this->getLoadedProductCollection();
foreach ($_productCollection as $_product):

    echo $this->helper('catalog/image')->init($_product, 'specialprice_image')->resize(158, 270);

    echo $_product->getResource()->getAttribute('specialprice_image')->getFrontend()->getValue($_product);

    echo $_product->getAttributeText('specialprice_image');

    $product = Mage::getModel('catalog/product')->load($_product->getId()); ?>
    echo $product->getAttributeText('specialprice_image');
endforeach;

The helper is giving me the placeholder url. Ther other methods are giving me nothing.

I hope someone can help me with this problem.

Now it works after editing the Mage_Catalog_Block_Product_List_Random Class

I just removed two lines of code:

$collection->addAttributeToSelect('*');
$collection->addStoreFilter();

The complete 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);
                $collection = $category->getProductCollection();
            } else { 
                $collection = Mage::getResourceModel('catalog/product_collection'); 
            }
            Mage::getModel('catalog/layer')->prepareProductCollection($collection);
            $collection->getSelect()->order('rand()');
            $numProducts = $this->getNumProducts() ? $this->getNumProducts() : 0;
            $collection->setPage(1, $numProducts)->load();

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

And in frontend I’m using this code:

<a href="<?php echo $_product->getProductUrl() ?>" title="<?php echo $this->htmlEscape($_product->getName()) ?>">
    <img src="<?php echo $this->helper('catalog/image')->init($_product, 'specialprice_image')->resize(158, 270); ?>" width="158" height="270" alt="<?php echo $this->htmlEscape($_product->getName()) ?>" />
</a>
