I am using codeigniter re-route to clean up some urls. I am aware that I can do
$route['product/(:num)'] = "catalog/product_lookup_by_id/$1";
But in some cases I have to add some extra parameters to the redirect url so that I get them as a param to the method. for example
$route['product_unique_and_rare'] = "catalog/product_lookup_by_id/{HERE I WANT SOME ADDITIONAL EXTRA PARAM}";
How to do this so that I get the value in the param of the method rather than the value in uri->resegment
