Hi Chemo, first of all i have to say Thank You for this great contribution. It works fine and was easy to install. But now i want to modificate it a little bit. I want to have the manufacturers name in the url additional to the product name. (e.g. www.mydomain.com/manufacturer-produkt-p-101.html) I know this must be possible when i put the manufacturers-id to the link parameters in the product-listing.php (something like this tep_href_link(FILENAME_PRODUCT_INFO, '$listing[manufacturers_id].$listing[products_id]'.... But i dont know how to modify the seo_class.php Can you give me a short hint how to manage this. Or is it possible that my thoughts are completly wrong and it must be handled in a complete different way? greetings from germany
