Custom posts and taxonomies url/permalink problems

Hi. I’m developing a web site for a company that sell tour packs all around the globe.

I was reading that the best way to achieve it is by using CPT and taxonomies… So I create a custom post type called “pack” (tour packs), and later custom taxonomy: “class” (for pack categorization).

The cpt works great: The archive page: “mysite.com/pack” list all packs like a charm.

BUT, there are things that doesn’t seem clear to me. And I don’t know if I’m missing something, or this is the natural wp behaviour.

1 PROBLEM:
Url structure doesn’t make sense:

For example, I write a tour pack for Rio de Janeiro in packs:

Ex: “Rio de Janeiro 2013” (PACK) -> “International” (CLASS)
URL: “mysite.com/pack/rio-de-janeiro-2013”

As you can see WP show the pack url without taxonomy:

This should be:

Ex: “Rio de Janeiro 2013” (PACK) -> “International” (CLASS)
URL: “mysite.com/pack/internactional/rio-de-janeiro-2013”

BTW, I can’t even create a proper page for taxonomy: “mysite.com/pack/internactional”. I only can achieve it by parsing a custom query like this: “mysite.com/pack?class=internactional”. But that kind of url are not seo friendly…

Also, have this structure allow to build human-friendly breadcrumbs for site navigation (“Home >> Packs >> International >> Rio de Janeiro 2013”)

2 PROBLEM:
Pagination not working:

Simple: In the CPT archive page the pagination works ok:

“mysite.com/pack/page/2/”

But what happen when I list taxonomies? The only way I can is like this: “mysite.com/pack?class=international” in order to list international packs. But navigations in this kind of pages with “?” queries doesn’t work. No 404 pages, only showing the same posts…

“mysite.com/pack?class=international”
– click “previous posts” –
“mysite.com/pack/page/2?class=international” (o.o?)
at least this should be:
“mysite.com/pack?class=international&page=2” (is redirected to the above url)

This of course, doesn’t work in any way…

POSIBLE SOLUTIONS:

I was reading a lot about this… but the docs are not rly clear to me, I’m kinda newbe in cpt stuff. I read something about url rewrite functions but seems complicated to me.

I’m also using custom fields to filtering results, and this mix make it more complicated…

I rly appreciate your opinion, maybe this post help other developers…

Thanks!
