Hi people, i saw there solutions of the problems with correct uri, i have problem with them. In view I have table with products, and I want to every name of product was link, which calls edit view of this product. So to the link i need to add as the third param product_id, but when I have in url after base_url ...product/edit/some nubmer, then if I click in menu for example HOME, my new generated uri is ...product/edit/home and its bad. It is overwritten just third param and last two stays. I need correct uri on cklick on home just
....home... Wher should be a problem? Rewrite modul I have turned on.
