Custom url for custom post types

Question

Is it possible to create a custom url for custom post types?

I have a directory website where in user can post or add a listing in many cities, I have a custom post type name ads. And all of the ads post titles are phone numbers. So when I create a new ads post in a city (e.g. Birmingham AL), the city will be save as a post meta post_ads_city,

Automatically the url will be mysite.com/ads/123-123-1234

Is it possible to make the url slug based on the city where the ads is posted? so it will be like this:

mysite.com/birmingham-al/123-123-1234 (if the postmeta "post_ads_city" = "Birmingham AL") mysite.com/las-vegas/123-123-1234 (if the postmeta "post_ads_city" = "Las Vegas")

Use add_rewrite_rule()

function custom_rewrite_rule() {
        add_rewrite_rule('^nutrition/([^/]*)/([^/]*)/?','index.php?page_id=12&food=$matches[1]&variety=$matches[2]','top');
    }
    add_action('init', 'custom_rewrite_rule', 10, 0);

you can use if ( 'myposttype' == $post->post_type ){} to make it post type specific. Weather you want to add it inside the function or wrapping the add action is up to you.
