I have created an EAV entity (that represents the brand) which can be associated to a product as an attribute. Now, I would like to add the name of the brand to the product view URL. I would like something like this:


Is there a way to extend the url rewrite for products view?


In order to create url key with "/" sign you need to override Mage_Catalog_Model_Product_Url's formatUrlKey() method.
You can do it like so:

class Vendor_Module_Model_Catalog_Product_Url extends Mage_Catalog_Model_Product_Url
     * Format Key for URL
     * @param string $str
     * @return string
    public function formatUrlKey($str)
        // added '/' character
        $urlKey = preg_replace('#[^0-9a-z\/.]+#i', '-', Mage::helper('catalog/product_url')->format($str));      
        $urlKey = strtolower($urlKey);
        $urlKey = trim($urlKey, '-');

        return $urlKey;


You can override beforeSave() method of the Backend Model of Catalog Product Urlkey attribute as following:

class Vendor_Module_Model_Catalog_Product_Attribute_Backend_Urlkey
    extends Mage_Catalog_Model_Product_Attribute_Backend_Urlkey 
     * Before save
     * @param Varien_Object $object
     * @return Mage_Catalog_Model_Resource_Product_Attribute_Backend_Urlkey
     * @overridden
    public function beforeSave($object)
        $attributeName = $this->getAttribute()->getName();

        $urlKey = $object->getData($attributeName);
        if ($urlKey == '') {
            $urlKey = "{$object->getBrandName()}/{$object->getName()}";
        $object->setData($attributeName, $object->formatUrlKey($urlKey));

        return $this;


Now while product is being saved, if url key empty it will automatically create an 'brand-name/name' like url. If it comes to category name it is a matter of magento configuration to or not to add category name at the begining of URL address.

Alternatively check out this free extension, it does exactly what you require: https://www.magentocommerce.com/magento-connect/custom-product-urls-seo.html
