I'm working on a WP website with many CPTs and Custom Taxonomies, but also using the regular "post" post type for the regular blog section of the site.

I want the blog posts and archive and categories to have /blog/ in their permalink, but also want to specify permalink structure for the other CPTs without the /blog/ interfering.

for example: I have an "events" CPT, which has a custom taxonomy named "ecat".

Now I got an archive page with permalink sitename.com/events working well

And the single event page has permalink like sitename.com/events/event-name as well.

But the custom taxonomy archive is in sitename.com/ecat/ategory-name. I want the custom taxonomy to have the cpt slug in its permalink like: sitename.com/events/ecat/category-name

Note: I don't want the single event to have the taxonomy term in its permalink.

My CPT registration Code:

    $labels = array(
    'name'                  => _x( 'Events', 'Post Type General Name', 'textdomain' ),
    'singular_name'         => _x( 'Event', 'Post Type Singular Name', 'textdomain' ),
    'menu_name'             => __( 'Events', 'textdomain' ),

$args = array(

    'description'           => __( 'Events custom post type', 'textdomain' ),
    'labels'                => $labels,
    'supports'              => array( 'title' ),

    'rewrite' => array( 'slug' => 'events','with_front' => false ),
);
register_post_type( 'events', $args );

My Custom Taxonomy register code:

//Event Categories
$labels = array(
    'name'                       => _x( 'Events Categories', 'textdomain' ),
    'singular_name'              => _x( 'Events Category', 'textdomain' ),

Welcome to WP StackExchange! You may want to try something like this, which uses the same rewrite setting as your register CPT:

$args = array(
    'rewrite'      => array('slug' => 'events/ecat', 'with_front' => false)
);
register_taxonomy( 'ecat', array( 'events' ), $args );

https://codex.wordpress.org/Function_Reference/register_taxonomy#Arguments

  • When I add this line to my taxonomy registration code - the taxonomy archive gives 404 for the sitename.com/events/ecat/category-name (Tried to resave the permalinks settings) – glng Jul 8 at 12:39

Prefix for post type post

Here you will find how to add prefix only for post type "post".

In the same way, you can add a prefix for the category. Suitable filter hooks are: category_rewrite_rules, pre_term_link.

add_filter( 'pre_term_link', 'se342399_pre_term_link', 20, 2 );
add_filter( 'category_rewrite_rules', 'se342399_category_rewrite_rules', 20 );

function se342399_pre_term_link( $termlink, $term ) 
{
    // add prefix only to links for terms of taxonomy "category"
    if ( $term instanceof \WP_Term && $term->taxonomy == 'category' ) {
        $termlink = '/blog' . $termlink;
    }
    return $termlink;
}

function se342399_category_rewrite_rules( $category_rewrite ) 
{
    if ( is_array($category_rewrite) ) 
    {
        $new_rules = [];
        foreach( $category_rewrite as $k => $v) {
            $new_rules[ 'blog/' . $k ] = $v;
        }
        $category_rewrite = $new_rules;
    }
    return $category_rewrite;
}

CPT slug before taxonomy ecat

To add slug of custom post type as prefix in term links of ecat taxonomy you can use one of the following methods:

  • add rewrite to $args parameter of register_taxonomy() (as @Tom suggested)

    "rewrite" => array( 'slug' => 'events/ecat', 'with_front' => false, )
    
  • or follow as in the case of categories, using hooks ecat_rewrite_rules ({$permastructname}_rewrite_rules) and pre_term_link
