This question is probably asked before but my language not being natively english i cant really find the answer:

I got a custom post type: products and custom (hierarchy) taxonomy: collection

in the taxonomy i got for axample: - paintings (parent tax) -- classic (sub tax) -- modern (sub tax)

now i want to reach my products via: collection/paintings/classic/classic-painting-1 but i have two problems:

Problem 1: sub tax doesn't have the parent tax in the url: collection/paintings/ and then collection/classic/.. it should collection/paintings/classic/

Problem 2: if i choose a product (eg. classic-painting-1) in collection/paintings/ it goes to products/classic-painting-1 in stead of collection/paintings/classic/classic-painting-1

i hope this big question has a simple answer, thank in advance

my codes for custom post type and taxonomy:

// Custom post type    
add_action('init', 'cptui_register_my_cpt_producten');
function cptui_register_my_cpt_producten() {
register_post_type('producten', array(
'label' => 'Producten',
'description' => '',
'public' => true,
'show_ui' => true,
'show_in_menu' => true,
'capability_type' => 'post',
'map_meta_cap' => true,
'hierarchical' => true,
'rewrite' => array('slug' => 'producten', 'with_front' => true),
'query_var' => true,
'menu_position' => '1',
'supports' => array('title','editor'),
'taxonomies' => array('category','post_tag','collectie'),
'labels' => array (
  'name' => 'Producten','singular_name' => 'Product','menu_name' => 'Producten','add_new' => 'Add Product','add_new_item' => 'Add New Product','edit' => 'Edit','edit_item' => 'Edit Product','new_item' => 'New Product','view' => 'View Product','view_item' => 'View Product','search_items' => 'Search Producten','not_found' => 'No Producten Found','not_found_in_trash' => 'No Producten Found in Trash','parent' => 'Parent Product',
)
) ); }

// Custom taxonomy
add_action('init', 'cptui_register_my_taxes_collectie');
function cptui_register_my_taxes_collectie() {
register_taxonomy( 'collectie',array (
  0 => 'producten',
),
array( 'hierarchical' => true,
    'label' => 'Collecties',
    'show_ui' => true,
    'query_var' => true,
    'show_admin_column' => false,
    'labels' => array (
  'search_items' => 'Collectie',
  'popular_items' => '',
  'all_items' => '',
  'parent_item' => '',
  'parent_item_colon' => '',
  'edit_item' => '',
  'update_item' => '',
  'add_new_item' => '',
  'new_item_name' => '',
  'separate_items_with_commas' => '',
  'add_or_remove_items' => '',
  'choose_from_most_used' => '',
)
) ); 
}

  • Can you provide the code you use to define your post type (products) and taxonomy? Not sure if you are doing this manually in functions.php or via plugin.

When asigning a post to a taxonomy, if you assign it to both a top-level and child term, the top-level will be used in the permalink. If you only select the child, I believe the parent term will be displayed as well. I agree, that this is not ideal and you may be able to work something out with wp_rewrite() but there's an easier way to get the parent term:

On the post page you'll need wp_get_post_terms(). This will return an array of terms associated with the post. If you only want the top-level term for the post, pass parent = 0 in the args array as I've done below.

$args = array( 'parent' => 0 );
$terms = wp_get_post_terms( $post->ID, 'taxonomy_name', $args );
echo '<pre>' . print_r( $terms, 1 ) . '</pre>'; // raw output
