Hi! Thank for the example! But can somebody help me to do for this example own structure? But only for the three taxonomies: www.mysite/type-deal/type-realty/city/address. In my situation address is post name for wordpress.

i have a post type with 2 different categories
how do i set up my permalink like this:
mysite.com/post_type/taxonomy_name/term/sub_term/post

i have a post type with 2 different categories
how do i set up my permalink like this:
mysite.com/post_type/taxonomy_name/term/sub_term/post

I wouldn't use category and tags with CPT's.

Better to register custom taxonomy terms and separate standard posts from custom post types.

Thank you for the example. At least it got me on the right track and I didn't miss anything.
All to fix one link... Doh!

Hi.

If I want to add a non-hierarchical taxonomy like WordPress tags to your code.
For example:

register_taxonomy ( 'taggs', array ('recipes'), array (
        'hierarchical' => false,
        'label' => 'Taggs'
    )
);

As a result, the link structure will be as follows:

http://example.com/taggs/tag-1,tag-2,tag-3

How else to add “recipes” to this taxonomy so that:

http://example.com/recipes/taggs/tag-1,tag-2,tag-3

Tried like this:

function add_clinic_permastructure () {
    global $ wp_rewrite;
    add_permastruct ('occasion', 'recipes/%occasion%', false);
    add_permastruct ('recipes', 'recipes/%occasion%/%recipes%', false);

    add_permastruct ('taggs', 'recipes/%taggs%', false);
    add_permastruct ('recipes', 'recipes/%taggs%/%recipes%', false);
}

In this case, the structure http://example.com/recipes/dinner,breakfast,brunch does not work (error 404).

How to tie these 2 taxonomies together?

Thank.

Looks like there is a typo in the code... Just change the implode( ',', $post_terms ) with implode( '/', $post_terms ). It'll replace the , with /.

Please let me know your results

amazing, thanks man!

Is there a simple way to use / instead of the , for mulitple categories?
It would be nice to have the hierarchical structure in the url.

The biggest problem with hierachical that I see is the add_permastruct function.
Therefore I have to register it like:

add_permastruct( 'recipes', 'recipes/%occasion%/%recipes%', false );
add_permastruct( 'recipes', 'recipes/%occasion%/%occasion%/%recipes%', false );
add_permastruct( 'recipes', 'recipes/%occasion%/%occasion%/%occasion%/%recipes%', false );

But if I do that, only the last one is active.

Any ideas? Thanks
