article and page urls

[ang3lx]

Hello
I would mod URL of CMS

for articles
www.site.com/[ID]-[slug-it]
www.site.com/en/[ID]-[slug-en]
example
www.site.com/22-nuovo-iphone-apple
www.site.com/en/22-new-iphone-apple

where I should modify to make this happen?

for pages
if I set parent of subpage, link has not parent slug
example
child page with slug "subpage" has "test" as parent page
url should be
www.site.com/test/subpage
but now is
www.site.com/subpage

are this two mods easy to implement?
