使用简单可配置的Magento分层导航过滤器

Question

I have a configurable product with simple products associated with it. Ex. Shoe with attributes Size and Width on the simple.

1. When I filter by width and size, it shows a configurable even though a simple product with that size and width don't exist.

I've seen this asked before here in numerous forms with no solutions. Does anyone know how to fix this functionality? I'm amazed how this is not built out of the box.

Answer 1

You have to customize the core file by copying it in the local/Mage directory.

Suppose that you have to variations size & color.

Open the file app\\code\\core\\Mage\\Catalog\\Model\\Layer.php

After the following code:-

$collection
  ->addAttributeToSelect(
    Mage::getSingleton('catalog/config')->getProductAttributes()
  )
  ->addMinimalPrice()
  ->addFinalPrice()
  ->addTaxPercents()
  ->addUrlRewrite($this->getCurrentCategory()->getId());

You have to customize it for the selected attribute:-

For example :-

if(isset($_GET['size']))
    {
        $query = 'SELECT value FROM aw_layerednavigation_filter_option_eav WHERE name="title" AND option_id IN ( '.$_GET['size'].' )';
        $results = $readConnection->fetchAll($query);
        $sizeLabels = array();
        foreach($results as $_r){
            $size_labels[] = $_r['value'];
        }

        $query = 'SELECT parent_id FROM advance_filter WHERE size IN ( '.implode(",",$size_labels).' ) AND qty > 0';

        $results = $readConnection->fetchAll($query);
        foreach($results as $_r){
            $size_prod_Ids[] = $_r['parent_id'];
        }   
    }
    $color_prod_Ids = array();
    if(isset($_GET['color']))
    {
        $query = 'SELECT value FROM aw_layerednavigation_filter_option_eav WHERE name="title" AND option_id IN ( '.$_GET['color'].' )';
        $results = $readConnection->fetchAll($query);
        $color_labels = array();
        foreach($results as $_r){
            $color_labels[] = strtoupper($_r['value']);
        }

        $query = 'SELECT parent_id FROM advance_filter WHERE color IN ( "'.implode(",",$color_labels).'" ) AND qty > 0';

        $results = $readConnection->fetchAll($query);
        foreach($results as $_r){
            $color_prod_Ids[] = $_r['parent_id'];
        }
    }
    $productIds = array_merge($size_prod_Ids,$color_prod_Ids);
    if(count($productIds) > 0){
        $collection->addAttributeToFilter('entity_id', array('in' => array_unique($productIds)));
    }

hope this will help..!!
