As most face with Magento, the breadcrumbs does not display the full path unless you navigate through the categories. Just hitting the URL causes the breadcrumbs to be home/product.
I came across this github https://github.com/dbashyal/Magento_Breadcrumbs. It works fine on our dev site but i'm curious if it will slow down our site at all or if there is anything that we need to change? Here is the observer.php file that does all the work:
<?php

class Technooze_Breadcrumbs_Model_Observer
{
/**
* Adds category to breadcrumb for product views
* originating from outside a category, for instance
* homepage or navigation links.
*
* @return Technooze_Breadcrumbs_Model_Observer
*/
public function addCategoryBreadcrumb(Varien_Event_Observer $observer)
{
if (!Mage::registry('current_category')) {
/* @var $product Mage_Catalog_Model_Product */
$product = $observer->getProduct();
$categoryIds = $product->getCategoryIds();
if(count($categoryIds)) {
/* @var $collection Mage_Catalog_Model_Resource_Product_Collection */
$collection = Mage::getModel('catalog/category')->getCollection();
$collection->addAttributeToSelect('name');
$collection->addAttributeToFilter('is_active', array('eq'=>'1'));
$collection->addAttributeToFilter('entity_id', array('in' => $categoryIds));
$collection->addAttributeToSort('entity_id', 'desc');
//$collection->setPageSize(1);
/* @var $category Mage_Catalog_Model_Category */
$category = $collection->getFirstItem();
if ($category->getId()) {
$product->setCategory($category);
Mage::register('current_category', $category);
}
}
}
return $this;
}
}
