Restructuring permalink with more than one taxonomies

Question

I have created three taxonomies named “city”, “company” and “profession”. link structure of this taxonomy is as follows:

/city/london

/company/cocacola

/profession/sales

I want to use city taxonomy at the end of company and profession taxonomy. in that way i would like to filter companies and professions depending on cities. see as follows:

/company/cocacola/london

/profession/sales/london

It is possible to do it in that way? if so, how can i do it? any alternatives?

Answer 1

That's quite possible by changing add_permstruct or filtering rewrite_rules. But what is your strategy for generating links for city? How will implement second taxonomy?

I would go for implementing this as rewrite rule for something like

add_filter( 'rewrite_rules_array', function( $rules ) {
    global $wp_rewrite;

    $new_rules = array(
        '(company|profession)/([^/]+)/([^/]+)/?$' => 'index.php?$matches[1]=$matches[2]&city=$matches[3]'
    );

    $rules = array_merge($new_rules, $rules);
    return $rules;
});

However, this isn't optimal and you will need to generate the bunch of supported rules (paging feeds). But you still need to generate links for them and its up to you!

cheers.
