This is great! Exactly what I needed!

I'm trying to get the posts to order by title on the Taxonomy page and not having much luck, is there an easy way of doing this I've missed?

Thanks

Hi,

If anyone still has a problem with the link structure in WordPress, then I would like to present you a plugin that solves this problem:

https://wordpress.org/plugins/wp-better-permalinks/

This plugin allows you do what with the code above and more - and all this with a few clicks in the admin panel. By using it you can achieve a friendly link structure:

Custom Post Type> Single Term> Post
Custom Post Type> Post (if there is no selected category)
Custom Post Type> Single Term

I invite you to check my plugin and if you like it - to recommend to others. I will be very grateful!

This is exactly what I have been looking for, it works great for me but I do get the following error message 'Undefined variable: permlink in /Users/...' 'on line 89'.

Great Work, i solved a little problem adding a line here:

add_filter( 'term_link', 'add_term_parents_to_permalinks', 10, 2 );
function add_term_parents_to_permalinks( $permalink, $term ) {
$term_parents = get_term_parents( $term );
$permlink = '';
foreach ( $term_parents as $term_parent )
$permlink = str_replace( $term->slug, $term_parent->slug . ',' . $term->slug, $permalink );
return $permlink;
}

because without this i retrieve an error when i navigate custom taxonomy archive.

And i have a question:
i have a problem with wpml. When i try to change language in custom taxonomy archive it doesn't work, anyone knows how to solve that?

Note: taxonomy has to be registered before post type.

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 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
