Permalink rewrite with custom post type and custom taxonomy

by

I think thats a quick one:

I’ve got:

  1. Custom post type: Food
  2. Custom taxonomy (Registered to Food): Fruits
  3. Terms in Fruits: Apple, Orange, Cherry

If I type in example.com/food?fruits=Apple,Cherry, I get all posts in Fruits with the terms Apple and Cherry, thats great!

But I would like to type in example.com/food/fruits/Apple,Cherry or example.com/food/Apple,Cherry to get the same result.

I´ve tried different permalink and rewrite plugins related to custom posts but nothing helped.

Thank you,

David

You have to build up the link structure by using filters post_link and post_type_link:

add_filter('post_link', 'territorio_permalink', 10, 3);
add_filter('post_type_link', 'territorio_permalink', 10, 3);

function territorio_permalink($permalink, $post_id, $leavename) {
if (strpos($permalink, '%territorio%') === FALSE) return $permalink;

// Get post
$post = get_post($post_id);
if (!$post) return $permalink;

// Get taxonomy terms
$terms = wp_get_object_terms($post->ID, 'territorio','orderby=term_order');
if (!is_wp_error($terms) && !empty($terms) && is_object($terms[0]))
$taxonomy_slug = $terms[0]->slug."https://wordpress.stackexchange.com/".$terms[1]->slug; //build here
else $taxonomy_slug = 'not-yet';

return str_replace('%territorio%', $taxonomy_slug, $permalink);
}

Where hotel is the post type and territorio is a hierarchical taxonomy.

In post type creation use:

'rewrite' => array( 'slug' => 'anything-you-want/%territorio%','with_front' => false),

Note: if you want deeper links, your build should go deeper:

$taxonomy_slug = $terms[0]->slug."https://wordpress.stackexchange.com/".$terms[1]->slug."https://wordpress.stackexchange.com/".$terms[2]->slug;
