On my WP blog my goal is to rewrite urls like:

domain/blog/**name_of_a_city**/title-of-the-article

Until now I have all my links written like this:

domain/blog/title-of-the-article/

Since I don't want to rewrite these existing articles url and change completely all the existing works, I decided to create a new custom post type named "Articles". I've been reading and trying many ways to do so, but I'm having some difficulties.

I thought the best way was to create taxonomies, since I will be adding many "taxonomy" (cities) as I write my blog. For example, if I write an article about Barcelona I would like to be able to add a city as a taxonomy and to see it withing my url.

domain/barcelona/this-article-title

Here is my codes:

I've been through the first stages:

-> Creation of a custom post type "Articles"

function cptui_register_my_cpts_article() {

/**

 */

$labels = array(
    "name" => __( "Articles", "rowling" ),
    "singular_name" => __( "Article", "rowling" ),
);

$args = array(
    "label" => __( "Articles", "rowling" ),
    "labels" => $labels,
    "description" => "",

Regarding the code base rewrites, you should be using %city% instead of city, as custom taxonomy used in slug param for rewrites should be enclosed in %TAXONOMY%

WordPress should still be able to redirect your old posts from the old URLs to the new ones. Did you add the filter on the post_type_link?

If you're doing this for a custom post type, you can use this plugin to customize the permalink in the core WordPress permalink configuration area: https://wordpress/plugins/custom-post-type-permalinks/

There's also this plugin: https://wordpress/plugins/permalinks-customizer/

Which allows you to use custom taxonomies in your permalink structure tags.
